With a half-life of 14 billion years, Thorium-232 is one of the safest, least radioactive elements in the world. Thorium-232 emits harmless alpha particles that cannot even penetrate skin, but when it becomes Th-233 in a Molten Salt Reactor, it becomes a potent source of power. Sunlight, living at high altitude and the emissions from your granite counter-top or a coal-burning plant are more hazardous than thorium-232.
LFTRs are even more fuel-efficient than uranium- fuelled MSRs, and they create little waste because a LFTR consumes close to 99% of the thorium-232. LWRs reactors consume just 3% of their uranium before the rods need to be changed. That’s like burning just a tiny part of a log while polluting the rest with chemicals you must store for years.
Just one pound of thorium can generate as much electricity as 1700 tons coal, so replacing coal-burning plants with LFTRs would eliminate one of the largest causes of climate change. That same pound (just a golf ball-size lump), can yield all the energy an individual will ever need, and just one cubic yard of thorium can power a small city for at least a year. In fact, if we were to replace ALL of our carbon-fuelled, electrical power production with LFTRs, we would eliminate 30 to 35% of all man-made greenhouse gas production.
From 1977 to 1982, the Light Water Reactor at Shippingport, Pennsylvania was powered with thorium, and when it was eventually shuttered, the reactor core was found to contain about 1% more fissile material (U233/235) than when it was loaded. (Thorium has also fuelled the Indian Point 1 facility and a German reactor.)
India, which has an abundance of thorium, is planning to build Thorium-powered reactors, as is China while we struggle to overcome our unwarranted fear of nuclear power. And in April, 2015, a European commission announced a project with 11 partners from science and industry to prove the innovative safety concepts of the Thorium-fuelled MSR and deliver a breakthrough in waste management.

Thorium is four times as plentiful as uranium ore, which contains only 1% U-235. Besides being almost entirely usable, it is 400 times more abundant than uranium’s fissile U-235. Even at current use rates, uranium fuels can last for centuries, but thorium could power our world for thousands of years.
Just 1 ton of thorium is equivalent to 460 billion cubic meters of natural gas. We already have about 400,000 tons of thorium ore in “storage”, and we don’t need to mine thorium because our Rare-Earth Elements plant receives enough thorium to power the U. S. every year. Australia and India tie for the largest at about 500,000 tons, and China is well supplied.
A 1 GW LWR requires about 1.2 tons of uranium each year, but a 1 GW LFTR only needs a one-time “kick start” of 500 pounds of U-235 plus 1 ton of thorium each year.
Waste and Storage
Due to their high efficiency, LFTRs create only 1% of the waste that conventional reactors produce, and because only a small part of that waste needs storing for 400 years – not the thousands of years that LWR waste requires – repositories much smaller than Yucca mountain would easily suffice.
Furthermore, LFTRs can run almost forever because they produce enough neutrons to make their own fuel, and the toxicity from LFTR waste is 1/1000 that of LWR waste. So, the best way to eliminate most nuclear waste is to stop creating it with LWRs and replace them with reactors like MSRs or LFTRs that can utilize stored “waste” as fuel.
With no need for huge containment buildings, MSRs can be smaller in size and power than current reactors, so ships, factories, and cities could have their own power source, thus creating a more reliable, efficient power grid by cutting long transmission line losses that can run from 8 to 15%. Unfortunately, few elected officials will challenge the carbon industries that provide millions of jobs and wield great political power. As a consequence, thorium projects have received little to no help from our government, even though China and Canada are moving toward thorium, and India already has a reactor that runs on 20% thorium oxide.
After our DOE signed an agreement with China, we gave them our MSR data. To supply its needs while MSRs are being built, China is relying on 27 conventional nuclear reactors plus 29 Generation III+ (solid fuel) nuclear plants that are under construction. China also intends to build an additional fifty-seven nuclear power plants, which is estimated to add at least 150 GigaWatts (GW) by 2030.
In 2016, the Chinese Academy of Sciences allocated $1 billion to begin buildingLFTRs by 2020. As for Japan, which began to restart its reactors in 2015, a FUJI design for a 100 to 200 MW LFTR is being developed by a consortium from Japan, the U. S. and Russia at an estimated energy cost of just three cents/kWh. Furthermore, it appears that five years for construction and about $3 billion per reactor will be routine in China.
Molten Salt Reactors are superior in many ways to conventional reactors.
In a Molten Salt Reactor, the uranium (probably Thorium in the future), is dissolved in a liquid fluoride salt. (Although fluorine gas is corrosive, fluoride salts are not.) Fluoride salts also don’t break down under high temperatures or high radiation, and they lock up radioactive material, which prevents it from being released to the environment.
As noted earlier, Dr. Alvin Weinberg’s Oak Ridge MSR ran successfully for 22,000 hours during the sixties. However, the program was shelved, partly for political reasons and partly because we [USA] favoured Admiral Rickover’s water-cooled reactors.
When uranium or thorium is combined with a liquid fluoride salt, there are no pellets, no zirconium tubes and no water, the source of the hydrogen that exploded at Chernobyl and Fukushima. The fluid that contains the uranium is also the heat-transfer agent, so no water is required for cooling. MSRs are also more efficient than LWR plants because the temperature of the molten salt is about 1300 F [700 C], whereas the temperature of the water in a conventional reactor is about 600 F [315 C], and higher heat creates more high-pressure steam to spin the turbines.
This extra heat can also be used to generate more electricity, desalinate seawater, split water for hydrogen fuel cells, make ammonia for fertilizer and even extract CO2 from the air and our oceans to make gasoline and diesel fuel. In addition, MSRs can be fueled with 96% of our stored uranium “waste” – spent fuel – and the fissile material in our thousands of nuclear bombs.
Because some MSR designs do not need to be water-cooled, those versions don’t risk a steam explosion that could propel radioactive isotopes into the environment. And because MSRs operate at atmospheric pressure, no huge, concrete containment dome is needed.
When the temperature of the liquid salt fuel rises as the chain reaction increases, the fuel expands, which decreases its density and slows the rate of fission, which prevents a “runaway” reaction. As a consequence, an MSR is inherently self-governing, and because the fuel is liquid, it can easily drain by gravity into a large containment reservoir. As a consequence, the results of a fuel “spill” from an MSR would be measured in square yards, not miles.
In the event of a power outage, a refrigerated salt plug at the bottom of the reactor automatically melts, allowing the fuel to drain into a tank, where it spreads out solidifies, stopping the reaction. In effect, MSRs are walk-away- safe.
Even if you abandon an MSR, the fuel will automatically drain and solidify without any assistance.
If the Fukushima reactor had been an MSR, there would have been no meltdown, and because radioactive by-products like caesium, iodine and strontium bind tightly to stable salts, they would not have been released into the environment. (In 2018 Jordan agreed to purchase two, 110 MW, South Korean molten salt reactors,)
USEFUL MSR BYPRODUCTS
Besides producing CO2-free electricity, fissioning U-233 in an MSR creates essential industrial elements that include xenon, which is used in lasers, neodymium for super-strength magnets, rhodium, strontium, medical molybdenum-99, zirconium, ruthenium, palladium, iodine-131 for the treatment of thyroid cancers and bismuth-213, which is used for targeted cancer treatments.
The trail of destruction continues from Episode 15.
Later in 2010, an Enbridge pipeline ruptured in Michigan, eventually “spilling” more than a million gallons of tar sands crude into the Kalamazoo River. When monitors at the Alberta office reported that the line pressure had fallen to zero, control room staff dismissed the warning as a false alarm and cranked up the pressure twice, which worsened the disaster. In 2018, Enbridge’s “cleanup” was still incomplete.
In 2013, a spectacular train wreck dumped 2 million gallons of North Dakota crude oil into Lac Megantic, Quebec, killing 47 residents and incinerating the centre of the town – but that’s just another page in the endless petroleum tale that includes Exxon’s disastrous, 2016 “spill” in Mayflower, Arkansas, that received scant notice from the press.
And in November 2013, a train loaded with 2.7 million gallons of crude oil went incendiary in Alabama, followed in December by a North Dakota conflagration.
2014 began with a fiery derailment in New Brunswick, Canada, and in October 2014, 625,000 liters of oil and toxic mine-water were “spilled” in Alberta.
July, August and September brought Alberta’s autumn, 2014 total to 90 pipeline “spills.” 2015 brought four, fiery oil train wrecks just by March, and 2016 delivered two Alabama pipeline explosions – one close to Birmingham.
In late 2015, California’s horrific, Aliso Canyon methane “leak” (think “geyser”) erupted, spewing forth 100,000 tons of natural gas, the equivalent of approximately 3 billion gallons of gasoline or adding 500,000 cars to our roads for a year.
The Southern California Gas Company finally managed to throttle the geyser in February, 2016. Incidentally, Aliso’s 100,000 tons of “leakage” is just 25% of California’s allowed leakage, which is an indication of the political power of the natural gas industry. (Five months later, a new headline appeared: “Massive Fracking Explosion in New Mexico”)
The Aliso “leak” caused the loss of 70 billion cubic feet (BCF) of gas that California utilities count on to create electricity for the hot summer months. As a consequence, the California Independent Service Operator, which manages California’s grid, estimated that due to Aliso, 21 million customers should expect to be without power for 14 days during the summer.
According to Reuters, (June 2016), “SoCalGas uses Aliso Canyon to provide gas to power generators that cannot be met with pipeline flows alone on about 10 days per month during the summer, according to state agencies.”
However, during the summer, SoCalGas also strives to fill Aliso Canyon to prepare for the winter heating season. State regulators, however, subsequently ordered the company to reduce the amount of gas in Aliso to just 15 BCF and use that fuel to reduce the risk of power interruptions in the hot summer months of 2016. Fortunately, State regulators have also said that they won’t allow SoCalGas to inject fuel into the facility until the company has inspected all of its 114 storage facilities.
The Aliso disaster wiped out all of the state’s Green House Gas (GHG) reductions from its wind and solar systems – and led to a USD 1.8 billion judgement against SoCalGas in September, 2021. In 2016, California officials also reported leakage at a San Joachim County storage facility that was “similar to, or slightly above, background levels at other natural gas storage facilities.”
“Combustion sources [unlike nuclear power], aren’t burdened with their true costs. Natural gas, for example, is not cheaper than nuclear or anything else. In 2016, our allowed leakage wipes wind/solar out by 4 times. In other words, ‘renewables’ in a gas state like California wipe out their benefits every 3 months because they depend on gas for most of their nameplate ratings. The Aliso storage was largely used to compensate for ‘renewables’ inevitable shortfall.
“The most important combustion cost is the unlimited downside risk of its emissions for the entire planet, but in February 2016, our CEC approved 600MW of added gas burning in the San Diego region simply because the San Onofre nuclear plant wasn’t running, due to possibly corrupt actions by SoCla Gas, SCE, Sempra Energy and Edison Intl.
“Such practices were prevented for 75 years by the 1935 PUHCA, but the Bush administration repealed it in 2005 after decades of carbon combustion-interest lobbying. Some states – not California – passed legislation to correct for the 2005 PUHCA repeal.”
There’s more: In August, 2016, the PennsylvaniaEPA admitted that oil and gas production in the state emitted as much methane as Aliso Canyon. The Aliso “leak” was deemed a disaster, but the hundreds of equally damaging Pennsylvania “leaks” were considered business as usual.
Finally, also in August, 2016, a thirty-inch pipeline exploded in southeast New Mexico, killing five adults and five children while leaving two other adults in critical condition in a Lubbock, Texas hospital.
All of this could have been avoided if, instead of pursuing intermittent, short-lived, carbon-dependent windmills and solar panels (Chapters 9 and 10), we had expanded safe, CO2-free Nuclear Power.
Dr. Wade Allison, in Nuclear is For Life, wrote: “Critics of civilian nuclear power use what they fear might happen due to a nuclear failure – but never has – but ignore other accidents that have been far worse: – The 1975 dam failure in China that killed 170,000; – The 1984 chemical plant disaster in Bhopal, India where 3,899 died and 558,000 were injured; – The 1889, Johnstown. PA flood that drowned 2,200; – The 1917 explosion of a cargo ship in Halifax, N. S. where 2,000 died and 9,000 were injured; – Turkey’s 2014 coal mine accident that took 300 lives; – The 2015 warehouse explosion in China that cost 173 lives. “
The list seems endless, but no one advocates destroying dams or closing chemical plants.
The way the world has reacted to the Fukushima accident has been the real disaster with huge consequences to the environment, but the accident itself was not.”
“In California, defective, Japanese-built steam generators at the San Onofre plant could have been replaced for about USD 600 million, but the plant is being decommissioned at a cost of USD 4.5 billion because of Fukushima and anti-nuclear zealotry. The plant could be replaced with two, CO2-free AP-1000 reactors for USD 14 Billion.” Mike Conley
In this foolish way, California lost the CO2-free electricity generated by San Onofre – 9% of California’s needs – which was replaced by carbon burning power plants and/or carbon-reliant wind and solar.
Nuclear plants are required to set aside part of their profits to pay the cost of decommissioning, but no such requirement is made of wind and solar farms. Neither are carbon companies required to pre-fund the removal of miles of pipelines, the cleanup of refinery sites, or the sealing of their abandoned wells.
I repeat, NO ONE has died from radiation created by commercial nuclear power production in Western Europe, Asia or the Southern and Western hemispheres, but up to 5,000,000 people die prematurely every year from the burning of coal, gas, wood and oil.
The original version of this chart, which rated nuclear power at 0.04 deaths per Terawatt hour, included thousands of LNT-predicted Chernobyl deaths that never happened.
As a consequence, this image, which reflects reality instead of LNT [Linear No Threshold] errors, reveals that nuclear power is far safer than initially thought, and that nuclear is actually 115 times safer than wind – not 4,340 times safer than solar – not 10, 3,000 times safer than natural gas, 27,000 times safer than oil – and coal is out of sight.
While we are at it, let’s explore resources necessary to build equivalent power facilities and the fuel required.

How Much Does it Take to Move that Much Materials?
Coming up next week, Episode 17 – All At Sea – The Best Technology. Not Used. Why?
What’s the Fossil Fuel Record? Millions of Air Pollution Deaths each year
Because the carbon industries are heavily subsidised, one might expect them to have exemplary safety and social records, but one would be wrong!
According to the Guardian, 6 Oct 2021 “The IMF found the production and burning of coal, oil and gas was subsidised by USD 5.9tn in 2020″ Or USD 11 million a minute every day. This is according to a startling new estimate by the International Monetary Fund. The IMF has noted before that existing fossil fuel subsidies overwhelmingly go to the rich, with the wealthiest 20% of people getting six times as much as the poorest 20% in low and middle-income countries.
The ash derived from burning coal averages 80,000 pounds per American lifetime. Compare that to two pounds of nuclear “waste” for the same amount of electricity. The world’s 1,200 largest coal-fired plants cause 30,000 premature U.S. deaths every year plus hundreds of thousands of cases of lung and heart diseases.
Generating the 20% of U.S. electricity with nuclear power saves our atmosphere from being polluted with 177 million tons of greenhouse gases every year, but despite the increasing consequences of Climate Change and Ocean Acidification, the burning of carbon to make electricity is still rising.
Scientific American, 13 Dec 2007: “Coal-fired plants expel mercury, arsenic, uranium, radon, cyanide and harmful particulates while exposing us to 100 times more radiation than nuclear plants that create no CO2. In fact, coal ash is more radioactive than any emission from any operating nuclear plant.”
In one year, a CO2-free, 1,000 MW nuclear plant creates about 500 cu ft of spent fuel that can be recycled to retrieve useful U-238, reducing its bulk by about 90%. (An average U. S. bathroom is about that size.) In that same year, a 1,000 MW coal plant creates 65,000 tons of CO2 plus enough toxic ash to cover an entire football field to a height of at least 200 feet.
Every year, we store 140 million tons of coal ash in unlined or poorly lined landfills and tailing ponds. In 2008, five million tons of toxic ash burst through a Tennessee berm (see below), destroying homes and fouling lakes and rivers.
Coal-fired power plants leak more toxic pollution into America’s waters than any other industry. (A June, 2013 test found that arsenic levels leaking from unlined coal ash ponds were 300 times the safety level for drinking water.)
And in 2014, North Carolina’s Duke Energy’s plant (now bankrupt) “spilled” 9,000 tons of toxic coal ash sludge into the Dan River. Why do they always say “spilled” – never “gushed?”
Coal companies like to promote their supposedly “clean coal,” which really means “not quite so filthy,” but despite making an attempt at carbon capture and storage (CCS) at a new power plant in Saskatchewan, the plant has been a failure. (Burning fossil fuels causes 4.5 million early deaths per year.)
CO2 removal devices use natural gas or electricity, which is usually generated by burning carbon. The moral hazard of removing CO2 from the air is that it justifies burning fossil fuels.
An electrical plant in Saskatchewan was the great hope for industries that burn coal.
In the first large-scale project of its kind, the plant was equipped with a technology that promised to pluck carbon out of the utility’s exhaust and bury it, transforming coal into a cleaner power source. In the months after opening, the utility and the government declared the project an unqualified success, but the USD 1.1 billion project is now looking like a dream.
Known as SaskPower’s Boundary Dam 3, the project has been plagued by shutdowns, has fallen way short of its emissions targets, and faces an unresolved problem with its core technology. The costs, too, have soared, requiring tens of millions of dollars in new equipment and repairs.
“At the outset, its economics were dubious,” said Cathy Sproule, a member of the legislature who released confidential internal documents about the project. “Now they’re a disaster….”
New York Times by Ian Austen, 29 March 2016, Ottawa
Even modern, 75% efficient coal-burners with thirty-year lifespans can’t compete with nuclear plants that have lifespans of 60 years and provide CO2-free power at 90% efficiency, and the new plants are even safer. In addition, our coal reserves will last 100 years at best. And as we “decarbonize”, we will require increasing amounts of electricity, and the only source of economical CO2-free, 24/7 power must be our new, super-safe, highly efficient nuclear reactors that cannot melt down.
Note: The word “efficiency,” AKA “capacity factor,” in this book means the amount of electricity created over an extended period by wind, solar, etc. compared to their maximum power rating. Unfortunately, the maximum power rating is often used to sell the project. For nuclear reactors, this figure is at least 90%, but it is 33% for windmills and just 19 -22% for pv solar – and solar panel efficiency degrades by 1% per year during their short, 20 year lifespan. (Thermal efficiency is a separate matter.)
When a gas pipeline exploded in 2010 at San Bruno, California, 8 people died, 35 homes were levelled and dozens more were damaged. In 2016, a federal government report stated that natural gas explosions cause heavy property damage, often with deaths, about 180 times per year– that’s every other day.
In 2010, British Petroleum’s Deepwater Horizon disaster in the Gulf of Mexico “spilled” 200 million gallons of oil and killed 11 workers and 800,000 birds. Prior to that, an explosion at a Texas BP refinery killed fifteen workers. And BP, which was also involved in the Exxon Valdez “spill” in Alaska’s Prince William Sound, is just one of the many oil companies that we subsidise with USD 2.4 billion every year.
“‘Evolution is driven by the tendency of all organisms to expand their habitat and exploit the available resources… Just as bacteria in a Petri dish grow until they have consumed all of the nutrients, and then die in a toxic soup of their own waste.”
Japan responded [to the 2011 Tōhoku earthquake] by closing its nuclear plants – a foolish move that has required the country to spend USD 40 billion per year on liquefied natural gas plus billions more for coal, which has created huge amounts of greenhouse gases. Another USD 11 billion per year has been spent to maintain their perfectly functional-but-idle reactors.
Nuclear power has been tarred by the Fukushima Daichi disaster, but the failure was NOT the fault of nuclear power. It was caused by repeated corporate lying, record falsifying and penny-pinching, by the lack of government enforcement of seawall height, by building too low to the ocean, and by installing backup generators in easily flooded basements.
Blaming nuclear power for Fukushima is like blaming the train when an engineer derails it by taking a turn at 70 mph that is posted for 30. (The Japanese Diet has stated that the Fukushima accident was not the fault of “nuclear power.”)
A few days later, Goodman’s article was read by Captain Reid Tanaka, a United States Navy professional with considerable expertise in nuclear matters who had been intimately involved during the meltdown – and Captain Tanaka presented a very different view:
“I was in Japan, in the Navy, when the tsunami struck and because of my nuclear training, I was called to assist in the reactor accident response and served as a key adviser to the US military forces commander and the US Ambassador to Japan. I spent a year in Tokyo with the US NRC-led team to assist TEPCO and the Japanese Government in battling through the casualty.
“My command (CTF 70) was the direct reporting command for the REAGAN (where we had control over REAGAN’S assignments and missions) and were in direct decision-making with REAGAN’S Commanding Officer and team. I don’t qualify to be called an “expert” in reactor accidents…, but I am well informed enough to know where my limits are and to see through much of the distortions on this issue….
“A Google search will tend to drive people to alarmist websites and non-technical news reports, but you could also find the dull, technical (yet truthful) places such as the IAEA or DOE…
“Numerous bodies of experts have weighed in and provided assessments and reports. A couple are quite critical of TEPCO and the Japanese nuclear industry and regulators.
“… the biggest problem the public has is … being able to distinguish the science-based, objective reports from the alarmist and emotionally charged positions that get the attention of the press, some of whom are self- proclaimed experts in some fields but NOT nuclear power: Dr. David Suzuki and Dr. Michio Kaku. Neither understand spent fuel, nor the condition of spent fuel pools….
“Dr. Suzuki is an award-winning scientist and a champion for the environment, but he is lacking any real understanding of spent fuel or radioactivity. “Bye-bye Japan?’ A headline grabbing sound-bite, but the math just doesn’t work…
“[Sometimes] the true experts cannot give a simple answer because there isn’t one, while those who have no science to back their claims have no compunction in saying the sky is falling and everyone else is lying.
“For the Navy, the contamination caused by Fukushima created a huge amount of extra work and costs for decontaminating the ships and our aircraft to ‘zero’, but [there was] no risk to the health of our people.
“REAGAN was about 100 miles from Fukushima when the radiation alarms first alerted us to the Fukushima accident. Navy nuclear ships have low-level radiation alarms to alert us of a potential problem with our onboard reactors. So, when the airborne alarms were received, we were quite surprised and concerned. The levels of contamination were small, but they caused a great deal of additional evaluation and work. REAGAN’s movements were planned and made to avoid additional fallout. Sailors who believe they were within five miles or so, were misinformed. Japanese ships were close; the REAGAN was not….
“There are former sailors who are engaged in a class-action suit against TEPCO for radiation sickness they are suffering for the exposure they received from Operation Tomodachi. The lead plaintiffs were originally sailors from REAGAN but now have expanded to a few other sailors from other ships. Looking at the claims, I have no doubt some of the SAILORS have some ailments, but without any real supporting information (I haven’t seen ANY credible information to that end), I do not believe any of their ailments can be attributable to radiation—fear and stress related, perhaps, but not radiation directly. Radiation sickness occurs within a ‘minutes/hours’ time frame of exposure and cancer occurs in a ‘years’ time frame. These sailors were not sick in either of these windows. I believe that many of them believe it, but I also believe most are being misled.”
The closure of Japan’s nuclear plants and its increased use of imported liquefied natural gas put an end to Japan’s long-standing trade surplus. But in 2015, bowing to financial realities and because of diminishing fear, Japan restarted the second of its reactors. As of May, 2018, seven reactors had been restarted, with many scheduled to follow.
Shortly thereafter, the U. S. media and many of the “Green” organizations began to report that a Fukushima worker had been “awarded compensation and official acknowledgment that his cancer [leukemia] was caused by working in the reactor disaster zone.” That’s wrong, and competent journalists who do adequate research should know it. Here are the facts:
The worker received a workman’s comp benefit package because he satisfied the statutory criteria stipulated in the 1976 Industrial Accident Compensation Insurance Act, which says that workers who are injured or become ill while working or while commuting to and from work, can receive financial aid and medical coverage. The worker spent 14 months at F. Daiichi. (October, 2012 to December 2013.)
In late December 2013, the worker felt too ill to work, so he went to a doctor, and was diagnosed with acute leukaemia in January, 2014. No link was made between his occupational exposure and his cancer. In addition, because the latency period between radiation exposure and the onset of leukaemia is 5 to 7 years, the worker did not get cancer from working at Fukushima. It was, in fact, a pre-existing condition that was exploited by opponents of nuclear power who routinely repeat convenient-but-wrong stories because being honest and accurate takes time, knowledge and integrity.
In 2016, anti-nuclear zealots began to fear-monger about the effects of Cesium-134 on fish while ignoring reports from NOAA and the Japanese government that stated, “Radioactive Cesium in fish caught near Fukushima Daiichi continues to dwindle. Of the more than 70 specimens taken in October, only five showed any Caesium isotope 134, the ‘fingerprint’ for Fukushima Daiichi contamination. The highest Cs-134 concentration was [associated] with a Banded Dogfish, at 8.3 Becquerels per kilogram. Half of the sampled fish had detectable levels of Cs-137, but all were well below Japan’s limit of 100 Bq/kg….”
These amounts are tiny, and the particles emitted from the Potassium-40, which we all contain, are more potent than the Caesium-137 emissions that many greens apparently fear.
There is 500,000 times more natural radiation in the ocean than the amount added by Fukushima.
Regarding the risk from remaining reactor material that many greens agonize over, Dr. Alex Cannarasubsequently wrote,
“As of late 2013, the spent fuel at Fukushima was 30 months old. That means that the rods and the fuel pellets within them are able to be stored in air. If any rods had never been in a reactor core, they have no fission products in them and are perfectly safe to take apart by hand.
“So, what do we have at Fukushima? We have some melted core materials (corium), which can be entombed. We have water containing a small amount of fission products like Cesium. And, we have a bunch of fuel assemblies that are very radioactive because of their internal creation of fission products when they were in their reactor cores. (No fission products are created when rods are out of cores, in pools or dry air storage.)
“Since the rods are at least 30 months out of fission-product production , one can see how quickly they’ve lost the need for cooling and the reduction in their radioactivity.
“Nuclear power has for its entire life, been the safest form of power generation. The EPA estimates that we lose more than 12,000 Americans every year to coal emissions. The Chinese lose 700,000, and the Indians, 100,000. To delay building nuclear power plants will cause diseases and deaths that could easily be avoided.”
“A nuclear power plant that melts down is less dangerous than a fossil fuel plant that is working correctly. [Because of their toxic ashes and emissions.] Fukushima illustrates that even a meltdown that penetrates containment is very little danger to the public when a few basic precautions are taken.” Andrew Daniels, author, “After Fukushima What We Now Know”.
No other technology produces energy as cheaply, safely and continuously on a large scale as nuclear power. No other energy source can match nuclear power’s low environmental impact, partly because its energy density is a million times greater than that of fossil fuels – and more so for wind or solar.
As of 2016, the world’s 400 + nuclear reactors created about 15% of our electricity. France, alarmed by the cost of petro-fuels, went to 70% nuclear in just 16 years, and Finland, now at 30%, is aiming for 60%. Sweden is adding 10.
Nuclear France emits about 40 grams of CO2/kWh, but Germany, the US, Japan and most industrialised nations emit 400 – 500 grams per kiloWatt hour – ten times more per kWh than heavily nuclear France. Compared to fossil fuel-reliant wind and solar farms, nuclear power is a gift from the energy gods.
Nuclear power, being CO2-free, is by far the most effective displacer of greenhouse gases, so how can my fellow “greens,” oppose nuclear power when the environmental costs of burning carbon-based fuels are so high?
Dr. James Lovelock, a patriarch of the environmental movement, has begged people to support nuclear energy: “Civilization is in imminent danger and has to use nuclear power, the one safe, available, energy source now or suffer the pain soon to be inflicted by an outraged planet.”
“In the core of just one reactor, the power density is about 338 million watts per square meter. To equal that with wind energy, which has a power density of 1 watt per square meter, you’d need about 772 square miles of wind turbines….
“Some opponents still claim that nuclear energy is too dangerous. Debunking that argument requires only a close look at the facts about Fukushima….
“Here’s the reality: The tsunami caused two deaths – two workers who drowned at the plant.
“It was feared that radiation from the plant would contaminate large areas of Japan and even reach the U.S. That didn’t happen. In 2013, the World Health Organization concluded: ‘Outside of the geographical areas most affected by radiation, even within Fukushima prefecture, the predicted risks remain low and no observable increases in cancer above natural variation in baseline rates are anticipated.
“High on my list of well intentioned dupes are those who praise science and are eager to confront Climate Change but refuse to accept nuclear power as an essential part of carbon-reduction strategies. They dismiss new reactor designs that they don’t understand, and then talk about how wind and solar power can ‘supply our needs.’
“They are wrong, but nuclear can supply our needs when people conquer their fears, educate themselves on the safety of nuclear power – and constructively join the fray. Until they do, they must accept their culpability in creating an overheated planet with millions of climate refugees.”
Only at the “illegal” plant at Chernobyl, which was designed to also make plutonium for bombs, with electricity being a by-product, has anyone died from radiation from nuclear power, but we’ve had tens of millions of coal, gas and petroleum-related, early deaths. Furthermore, our reactors, by generating electricity from the 20,000 Russian warheads we purchased in the Megatons to Megawatts program, have become the ultimate in weapons-reduction techniques.
What about 3-Mile Island, Chernobyl and Fukushima? We’ll examine each of them, but it is important to remember that nuclear plants have been supplying 15% of the world’s electricity, while creating no CO2, for 16,000 reactor-years of almost accident-free operation. And the reactors that have powered our nuclear Navy for more than 50 years have similar safety records. (Naval reactor fuel can be up to 90% U-235.)
Three Mile Island
In March, 1979, two weeks after the release of the popular movie, The China Syndrome, a partial meltdown of a reactor core due to a stuck coolant valve and design flaws that confused the operators, caused mildly radioactive gases to accumulate inside one of the reactor buildings.
After the gases were treated with charcoal, they were vented, and a small amount of contaminated water was released into the Susquehanna River. No one died or was harmed.
However, when an AP reporter described a “bubble” of hydrogen inside the reactor building in a way that led people to think that the plant was a “hydrogen bomb,” many residents fled, which caused more harm than the accident.
In fact, radiation exposure from Three Mile Island was far less than the amount of radiation that pilots and airline passengers receive during a round-trip flight between New York and Los Angeles [1 mrem, or 1 microSivert – 100 times less than average yearly background exposure in the area around Three Mile Island]. Furthermore, in the following decades, more than a dozen studies have found no short or long-term ill effects for anyone, whether they were downwind or downstream from the plant or at it – and since then, operator training and safety measures have greatly improved.
Despite all of the fear and panic, nothing happened. No one died, and no one got cancer, but the media-hyped event at Three Mile Island came very close to shutting down all progress in American nuclear power. Because of the radiophobia generated by our sensation-seeking press and fervent greens, neither of whom bothered to check the facts, many proposed reactors were replaced by coal plants, and in the following decades, pollution from those plants brought premature death to at least 500,000 Americans.
In 1986, during a test ordered by Moscow that involved disabling the safety systems, a portion of the core of the reactor, which had design hazards not present in Western reactors, was inadvertently exposed. (The RKMB reactor at Chernobyl was long judged to be dangerous by scientists outside of the Soviet Union.)
As Dr. Spencer Weart wrote in The Rise of Nuclear Fear, “In short, for Soviet reactor designers, safety was less important than building ‘civilian’ reactors that could produce military plutonium if desired, and building them cheaply.”
This negligence led to a steam/hydrogen explosion that released radioactive gases into the atmosphere because the reactor had no effective containment structure. In contrast, no U.S. reactor contains flammables. Each has a reinforced concrete containment structure that can survive an airliner hit, and every plant is strictly regulated by the NRC.
There has never been a source of energy as safe or kind to the environment as nuclear power, and the reason for the safety is regulation.
Every responsible nation similarly regulates its nuclear power plants and shares information and training practices via international agencies. This cooperation, which was expanded after Three Mile Island, resulted in so many improvements that civilian nuclear power climbed from 60% up-time in the sixties to at least 90% today.
For three days, Soviet authorities hid the [Chernobyl] disaster and delayed evacuating the area, coming clean when radiation readings across Europe began to rise. (The government also failed to distribute iodine tablets, which could have protected thousands from airborne Iodine-131, which is readily absorbed by the thyroid, particularly in the young. (A body with an abundance of benign I-127 is less likely to absorb I-131.)
Chernobyl failed due to bad design, Moscow’s interference, poor training and a system that forbade operators from sharing essential information about reactor problems. It is the only “civilian” reactor accident where radiation directly killed anyone. Initially, approximately eighteen firefighters died from intense radiation. Yet, with design changes and proper procedures, several similar reactors still operate in the former Soviet Union.
Metsamor, a nuclear power plant in Armenia, (former USSR), also has no containment structure. The European Union has urged Armenia to close down the site for years, and offered $289 million to finance shutting down the plant…
(A round trip flight for the U. S. to Chernobyl will expose travellers to twice as much additional background radiation as their 2-day tour in the exclusion zone, which even includes a tour of the damaged plant).
Furthermore, the deformed and brain-damaged “Chernobyl children” that sensation-seeking TV programs occasionally feature are no different from similarly afflicted children elsewhere in Europe who received no fallout, but that information is never provided by anti-nuclear activists and the media. (Since Chernobyl, cancer rates in the Ukraine have been about 2/3 of the rate in Australia.)
Because of the erroneous, dangerous LNT theory and many dire predictions from people like Helen Caldicott (coming up in future episodes), many thousands of badly frightened European women endured needless abortions because they had become convinced that they were carrying monster babies.
However, the quake destroyed the plant’s connections to the electrical grid, which required emergency generators to power the systems that cooled the still-hot reactors.
Although three of Tepco’s six nuclear reactors were off-line when the quake struck, five were eventually doomed because: 1. In 1967, Tepco removed 25 meters from the site’s 35-meter seawall to ease bringing equipment ashore. 2. Tepco replaced the original seawall with only a six-meter seawall. 3. The Japanese government advised Tepco to raise it, but Tepco declined – and the government did nothing. 4. Tepco had inexplicably placed five of its six emergency generators in the basements. 5. The tsunami flooded all but #6. 6. Batteries powered the controls for about 8 hours, and then failed. Without coolant, meltdown was assured.
Reactors 1 – 4 are useless, and number 5 is damaged, but reactor 6 was unaffected because its back-up equipment was intelligently sited well above the tsunami’s reach. Reactor 6 is capable of producing power, but it has not been started, largely because of the anti-nuclear hysteria fanned by most of the Japanese press.
There were warnings: All along the coast, ancient “Sendai stones” have been warning residents to avoid building below 150 feet above sea level for centuries.
The Onagawa nuclear plant, which was closer to the epicenter of the quake, also survived the quake, and its 45-foot high seawall easily blocked the tsunami. The tsunami took more than 15,000 lives, but Fukushima’s seawall failure took the lives of just two workers who drowned.
Remembering Leslie Corrice’s words from Episode 11, Corrice’s dismay over the results of radiophobia are echoed by many professionals, one being Dr. Antone “Tony” Brooks, who grew up in “fallout-drenched” St. George, Utah, which led him to study radiation at Cornell University. For an excellent, short video of the conclusions he reached, please visit:
The belief that tiny amounts of radiation can be lethal created ALARA – As Low As Reasonably Achievable – an anti-nuclear bias that has permeated our regulations for decades. However, “reasonably” is vague, and “achievable” depends on technology, not health effects.
For example, the World Health Organisation has set a public exposure limit for tritium from nuclear power plants of 0.1 mSv per year. Canada’s reactors comply with this limit, but due to ALARA, the limit in the USA is 0.04 mSv per year. Why? Because it is achievable – not because it is necessary.
Tritium (also known as hydrogen-3), is often used in watches and emergency exit signs. It is also present in our food and water. Furthermore, its tiny nucleus emits a particle so slow that it cannot even penetrate skin. In comparison, the Potassium-40 in our omnipresent banana emits beta particles that are 230 times as energetic, but no one worries about those deadly bananas.
LNT and ALARA can easily lead to absurdities: For example, airline passengers are exposed to about 20 times more cosmic radiation than those at ground level, but despite the dire predictions of LNT, they experience no more cancer than those who don’t fly. Should jets be required to fly at low altitudes, where they produce more greenhouse gases, just to satisfy ALARA – and what about the flight attendants and pilots who constantly work in higher levels of cosmic radiation?
As Radiation detection technology improves, ALARA just increases fear.
Caesium-137 from Fukushima is detectable, so Counter Punch complains of Blue Fun tuna containing 0.0000077 mSv per 7 oz serving [200 grams], writing “… no radiation exposure of any kind is safe”.
It is wasteful to spend money “protecting” people from tiny amounts of radiation. Instead, let’s finance programs that help people stop smoking, which brings carcinogens like cyanide, formaldehyde, ammonia, carbon monoxide and nitrogen oxide into intimate contact with their lungs. (Smoking related diseases kill 5 million people per year).
Radiation exposure in reactor buildings is so low that it isn’t an issue, but educating the public on basic environmental radiation is a very critical issue.
For example, after Fukushima, lack of accurate radiation knowledge and the media’s eagerness to hype radiation issues caused a run on potassium iodide [KI] pills along our west coast, but no media explained that this was pointless. Pharmacies ran out, and some patients who needed KI couldn’t get it, while those who needlessly took it actually raised their chances of disease because too much KI can cause thyroid malfunction.
“Radiation safety limits have been ratcheted down from 150 mSv/year in 1948 to 5 mSv/y in 1957 to 1 mSv/y in 1991 without supporting evidence by relying on the erroneous LNT model. EPA limits are set 100 times lower than levels that could cause harm. ALARA leads people, the press, and Big Green to falsely conclude that any radiation exposure may kill you.”
James Conca, in Forbes: “There are some easy decisions to make that will save us a trillion dollars, and they could be made soon by the Environmental Protection Agency. The EPA could raise the absurdly low radiation levels considered to be a threat to the public. These limits were based upon biased and fraudulent “research” in the 1940’s through the 1960’s, when we were frightened of all things nuclear and knew almost nothing about our cells’ ability to repair damage from excess radiation.
“These possible regulatory changes have been triggered by the threat of nuclear terrorism and by the unnecessary evacuation of tens of thousands of Japanese after Fukushima Daiichi, and hundreds of thousands of Russians after Chernobyl. There, the frightened authorities were following U. S. plans that were created because of the ALARA policy (As Low As Reasonably Achievable) that has always been misinterpreted to mean that all forms of radiation are dangerous, no matter at what level. It’s led to our present absurdly low threat level of 25 millirem.
“Keep in mind that radiation workers can get 5,000 mrem/year and think nothing of it. We’ve never had problems with these levels. Emergency responders can get up to 25,000 mrem to save human lives and property. I would take 50,000 mrem just to save my cat.
“This wouldn’t be bad if it didn’t have really serious social and economic side-effects, like pathological fear, significant deaths during any forced evacuation, not receiving medical care that you should have, shutting down nuclear power plants to fire up fossil fuel plants, and a trillion-dollar price tag trying to clean up minor radiation that even Nature doesn’t care about.”
Approximately 100,000 people were evacuated from the Fukushima area after the meltdown, and by September, 2013, about 1,200 evacuees had died from suicide and the stress of the excessive evacuation.
Dr. Brian Hanley: [Fukushima] “If no evacuation had occurred, and everyone had lived outdoors with no precautions, at most 15 cancer deaths might have happened, but probably none.
“People have been going to radioactive spas in Ramsar, Iran for a long time without ill effect. In a 2-week visit, the dose would be a maximum of 10 mSv. That is 6 to 80 times more radioactive than the evacuation zone of Fukushima.”
“To enable nuclear power, the NRC must renounce the non-scientific basis for LNT and ALARA”
LNT [Linear No Threshold Theory] was pushed through the U.N. by Russia and China in the 1950’s to stop America’s above-ground weapons testing. It worked, but it also caused a worldwide fear of radiation below levels that are dangerous.. The radiation safety people liked it because it seemed so… conservative. But it has become an ideology “ruled by hysteria and fuelled by ignorance.” Dr. Kathy Reichs, Society for the Advancement of Education.
Dr. Tim Maloney: “Anyone living permanently in the green zone would only receive a dose rate equal to twice the rate in Colorado, where the cancer rate is less than the US average. The dose rate in the dark red regions is 1/3 of the safety threshold set by the International Commission on System of Radiological Protection in 1934. Even by today’s extreme standards, this level of exposure carries no known cancer risk.
“Anxious to impress, officials and reporters donned white suits and masks, which made good TV but did nothing for the child who saw the school playground being dug up by workers who were afraid of an unseen evil called radiation. Unfortunately, most people see their fears confirmed as fact when workers and officials dress this way. An open-necked shirt with rolled-up sleeves, a firm hand shake and a cup of tea would be a better way to reassure.”
Imagine the anxiety created by clueless officials who provided useless information, as when a school official warned parents that the radiation intensity was 0.14 micro Sieverts per hour, which was meaningless because the normal radiation level in some Japanese cities can be five times that high.
Fukushima Fear of Radiation Killed People
In 2012, UNSCEAR stated, “…no clinically observable effects have been reported and there is no evidence of acute radiation injury in any of the 20,115 workers who participated in Tepco’s efforts to mitigate the accident at the plant.”
A year later, UNSCEAR added: “Radiation exposure following the accident at Fukushima Daiichi did not cause any immediate health effects. It is unlikely [that there will be] any health effects among the general public and the vast majority of workers.”
And in an April, 2014 follow-up, UNSCEAR reported that, “Overall, people in Fukushima are expected on average to receive less than 10 mSv due to the accident over their whole lifetime, compared with the 170 mSv lifetime dose from natural background radiation that most people in Japan typically receive.”
Finally, in October, 2015, UNSCEAR confirmed that none of the new information accumulated after the 2013 report “materially affected the main findings in, or challenged the major assumptions of, the 2013 report.” However, despite these positive reports, as of November, 2016, most of the 150,000 people who were forced to evacuate still lived in temporary housing.
Dr. Jane Orient, who practices internal medicine agreed: “The number of radiation casualties from the meltdown of the Fukushima nuclear reactors stands at zero. In Fukushima Prefecture, the casualties from radiation terror number more than 1,600… The U.S. is vulnerable to the same radiation terror as occurred in Japan because of using the wrong dose-response model, which is based on the linear no- threshold hypothesis (LNT), for assessing radiation health risks.”
“The BABYSCAN, a whole-body counter (WBC) for small children, was developed in 2013, and units have been installed at three hospitals in Fukushima Prefecture. Between December, 2013 and March, 2015, 2702 children between the ages of 0 and 11 have been scanned, and none had a detectable level of cesium-137.” (The anti-nuclear crowd had been obsessing about exposure to cesium-137.)
Positive reports like this rarely appear in our American press, which frustrates professionals like Leslie Corrice, a former nuclear power plant operator, environmental monitoring technician, health physics design engineer, public education coordinator and emergency planner who writes the informative and highly respected blog, The Hiroshima Syndrome.
“As long as the LNT theory is maintained, our fear of radiation will continue to damage the psyche of all humanity, restrict the therapeutic and healing effects of non-lethal doses of radiation, limit the growth of green nuclear energy, and needlessly prolong the burning of fossil fuels to produce electricity.
“In 1987, when I was frustrated because it seemed like the major news outlets bent over backwards to broadcast negative nuclear reports while seemingly ignoring anything positive, a former Press manager with a major news outlet in Cleveland took me aside and gave me the facts of life.
“He first explained that the Press is a moneymaking venture. The ratings determine advertising income; the lifeblood of the business – and the surefire money-makers were war, presidential elections, natural disasters and airline crashes.
“Turning to Three Mile Island, he said the ratings sky-rocketed and stayed that way for the better part of two weeks. In the years that followed, the media found that negative reports caused an increase in ratings, and positive stuff didn’t. This trend slowly dwindled, but Chernobyl re-ignited the ratings impact of nuclear accident reporting and proved that broadcasting the negative was better for business…
“He added that the media might someday entirely ignore the positive and only report the negative in regard to nuclear energy, and he speculated that all it would take was one more accident. Unfortunately, he was right. Fukushima has pushed the world’s Press into the journalistic dark side. My Fukushima Updates blog has lashed the Japanese Press and the world’s news media outside Japan severely for primarily reporting the negative…. A recent example concerns the child care thyroid study in Fukushima Prefecture during the past four years.
“On October 5, 2015, four PhDs in Japan alleged in the Tsuda Report that the Fukushima accident had spawned a thyroid cancer epidemic among the prefecture’s children, which contradicted the Fukushima Univ. Medical School, Japanese Research Center for Cancer Prevention and Screening, and National Cancer Center, which all found that the detected child thyroid precancerous anomalies in Fukushima Prefecture cannot be realistically linked to the accident. Regardless, the Tsuda Report’s claim made major headlines in Japan, then spread to mainstream outlets outside Japan, including UPI and AP.
“Here’s the problem. In December 2013, a scientific report was published on a comparison of the rate of child thyroid, pre-cancerous anomalies in Fukushima Prefecture with the rates in three prefectures hundreds of kilometers distant: Aomori, Yamanashi and Nagasaki.
“The Fukushima University medical team studying the issue had discovered that there was no prior data on child thyroid cancer rates in Japan, so there was nothing to compare the 2012 results to.
“Because of the furor caused by the original release of their findings in 2012, the team decided to take matters into their own hands and offer free testing to volunteer families in the distant prefectures. Nearly 5,000 parents took advantage of the opportunity and had their children screened.
“What was found was completely unexpected. The abnormality rates in Aomori, Yamanashi and Nagasaki Prefectures were actually higher than that discovered in Fukushima Prefecture, which conclusively indicated that the radiation from the Fukushima accident had no negative impact on the health of the thyroid glands in Fukushima’s children. Just one Japanese Press outlet mentioned the 2013 discovery at the very end of an article about a few more children being found to have the anomalies in Fukushima….
“On the other hand, when a maverick team of four Japanese with PhDs publish a highly questionable report – full of so many holes that it should be tossed into the trash – alleging a severe cancer problem caused by the Fukushima accident, it gets major coverage inside Japan and significant coverage by the world’s mainstream press!
“It is important to emphasize that the Tsuda Report fails to acknowledge the fact that Prefectures unaffected by the Fukushima accident had the higher anomaly rates. (Which is why the Tsuda Report is worthy of the trash heap.)
“The media might not make money off sharing the good news about Fukushima, but they are committing a moral crime against humanity by not doing it.”
Dr. Zbigniew Jaworowski, MD PhD, DSc, former Chairman of the United Nationals Scientific Committee on the Effects of Atomic Radiation (UNSCEAR): “What is really surprising, however, is that data collected by UNSCEAR and the Forum show 15% to 30% fewer cancer deaths among Chernobyl emergency workers and about 5% lower solid cancer incidences among the people on the Bryansk district (the most contaminated in Russia) in comparison with the general population. In most irradiated group of these people (mean dose of 40 mSv) the deficit of cancer incidence was 17%.”
Because of their daily exposure to low levels of radiation, which seems to stimulate the DNA repair system, nuclear power plant workers get one third fewer cancers than other workers. They also lose fewer workdays to accidents than office workers.
Knowing this, it is not surprising that, when steel containing cobalt-60 was used to build Taiwan apartments, which exposed 8,000 people to an additional 400 mSv of radiation during some twenty years, cancer incidence was sharply down, not up 30% as Linear No Threshold Theory would have predicted.Instead, the residents’ adaptive response to low- level radiation seems to have provided health benefits. The following chart reveals lower cancer rates for those who receive extra low-level radiation vs. those who only get background radiation.
In 2015, a study of bacteria grown at a dose rate 1/400 of normal background radiation yielded a reduction in growth, but when the cells were returned to normal background radiation levels, growth rates recovered. The conclusion: Insufficient radiation can yield harmful results.
Therefore, it seems reasonable that radiation limits should be the same regardless of the source of the radiation. Nevertheless, nuclear plants are held to a standard 100 times higher than coal plants, which actually emit moreradiation than nuclear power plants. Per unit of electricity created, the fly ash emitted by a coal power plant exposes the environment to 100 times more radiation than a nuclear plant’s on-site-stored spent fuel – it’s so-called “waste”, 90% of which can be consumed in modern reactors. (Granite buildings irradiate their occupants more than nuclear power plants.)
“Workers employed in fifteen utilities that generate nuclear power in the U. S. have been followed for up to 18 years between 1979 and 1997.
“Their cumulative dose from whole body radiation has been determined from records maintained by the facilities and by the Nuclear Regulatory Comm. and the Energy Department.
“Mortality in the cohort … has been analyzed with respect to individual radiation doses. The cohort displays a very substantial healthy worker effect, i.e. considerably lower cancer and non-cancer mortality than the general population.”
The largest circle (red) represents a radiotherapy tumour dose;
The green circle is a recoverable dose to normal tissue near the tumour;
The dark green circle is a dose with a 100% safety record.
The tiny black dot in the smallest circle represents the limit recommended by current regulations due to LTN.
In Radiation and Health, Hendrickson and Maillie wrote “…during radiation therapy for cancer, we’ve learned that chromosome damage to lymphocytes can be reduced by up to 50% if a small dose is given to the cells a few hours before the larger ‘cancer-killing’ dose is administered.”
In the southwest Indian state of Kerala, children under five have the lowest mortality rate in the country, and life expectancy is 74 despite background radiation rates that can range as high as 30 times the global average.
For thousands of years, Keralites have lived with radiation three times the level that caused the evacuation at Fukushima, where the limit was, on July, 2016, just 20 mSv. In contrast, some sections of Kerala experience 70 mSv, with a few areas measuring 500 – and many Keralites also eat food that is five times as radioactive as food in the United States.
Despite these radiation levels, cancer incidence in Kerala is the same as the rate in greater India, which is about 1/2 that of Japan’s and less than a third of the rate in Australia. As the linked article says, “Cancer experts know a great deal about the drivers of these huge differences, and radiation isn’t on the list.”
In Kerala, scientists have been working with a genuinely low rate of radiation exposure that mirrors what would have been the case in Fukushima if the Japanese officials hadn’t panicked and needlessly evacuated so many thousands of people.
So, why did they? Partly from fear, but primarily because most radiation protection standards have been derived from LNT bias and studies of Japanese atomic bomb victims who received their dose in a very short time, and being bombed is very different from living for years with a slightly higher radiation level.
Kerala also confirms our modern knowledge of DNA repair- namely that radiation damage is not cumulative at background dose rates up to 30 times normal, and that 70 mSv over a lifetime does nothing. In fact, the concepts of an “annual dose” or a “cumulative dose” are misleading. Instead, evidence reveals that an annual exposure to 100 mSv is comparable to a dose of zero because it doesn’t exceed a person’s capacity for repair.
In the past, when experts discussed these issues they couldn’t consider delivery rates or DNA repair because the power and mechanisms of DNA repair were not known until long after Muller’s LNT theory became dogma. As a consequence, the suffering caused by this obsolete “science” has been immense. (UK radiation expert Malcolm Grimston has characterised the Fukushima evacuation as being “stark raving mad”).
When the Japanese government lifted the evacuation orders because the radiation level had dropped to 20 mSv, 80 % of the residents refused to return because of their fear of radiation despite the fact that the most highly irradiated areas near the plant received only 1/5 of the lowest dose linked to a detectable increase in cancer. (At Guarapari beach in Brazil, residents often bury themselves in sand that yields 340 mSv without ill effect.)
We should be concerned about genuinely dangerous isotopes, but we shouldn’t waste energy and money cleaning up minor radioactivity that doesn’t do anything – but that is what we are doing.
Despite our learning that our cells have amazing repair abilities, LNT advocates still create the radiophobia that caused the extreme evacuations at Fukushima and the flood of needless, fear-induced European abortions that followed Chernobyl. In my opinion, people who refuse to examine the evidence that negates this discredited illusion have abandoned their integrity.
October, 2020. New U.S. Department of Energy research indicates that at low doses, biological reactions are often unrelated to those that occur at high levels. The influential Linear-No-Threshold model, which predicted that acute exposure damage can be extrapolated linearly to low dose exposures—was flawed. In fact, small amounts can have an adaptive positive effect. In addition, it appears that cells communicate with each other and a dose to one affects the cells around it.
Near the end of the 20th century, researchers at the Massachusetts Institute of Technology (MIT) discovered that DNA strands can break and repair about 10,000 times per day per cell, (this is not a typo), and that a 100 mSv per year dose increases the number of breaks by only 12 per day.
“… MIT discovered that DNA strands can break and repair about 10,000 times per day per cell, (this is not a typo), and that a 100 mSv per year dose increases the number of breaks by only 12 per day.“
In addition, the majority of DNA breaks are caused by ionised oxygen atoms from the normal metabolism that constantly occurs within our cells. And because DNA is a double helix, the duplicate information in the other strand lets enzymes easily repair single strand breaks. In fact, our cells have been repairing DNA breaks since forever, and they have become extremely good at it.
DNA damage, due to environmental factors and normal metabolic processes inside the cell, occurs at a rate of 1,000 to 1,000,000 molecular lesions per cell per day. A special enzyme, DNA ligase (shown here in color), encircles the double helix to repair a broken strand of DNA. DNA ligase is responsible for repairing the millions of DNA breaks generated during the normal course of a cell’s life.
Adaptive Response – The vaccination effect called Hormesis
“Radiation from unstable isotopes is always decreasing. That’s what the ‘half-life’ for an isotope expresses. Going back in time is going back to much higher radiation environments – 8 times more for U-235 when photosynthesis began to make oxygen common in air, and oxidation made elements like Uranium soluble in water. Living things were, back then, even more intimately in contact with radioactive isotopes.
“So how did life survive higher radiation, and how did it survive the increasing oxygen atmosphere, which corrodes life’s hydrocarbons into CO2 and water?
“The answer is simple: Nature evolved repair mechanisms. Each cell repairs proteins or digests badly malformed cells. Each cell repairs genetic material before it’s copied for reproduction.
“A DNA or protein molecule, or one of the many repair molecules in our cells, doesn’t know if a bond has been broken by an oxidizing radical, an alpha particle, or a microbial secretion. Our cellular-repair systems have evolved to fix defects regardless of cause. Thus, Nature has, for billions of years, been able to deal with chemical and radiation threats. Today, chemical threats have increased because of industry, but radiation threats have decreased.
“Therefore, we should not be surprised by the absence of radiation deaths at Fukushima and the small death rates in and around Chernobyl.”
We have also learned that low dose irradiation of the torso is an effective treatment for malignant lymphomas. Fear of radon has been hyped by the EPA’s devotion to the LNT theory, and their efforts have greatly assisted those who sell and install radon-related equipment, whether needed or not. (Studies of every US county have revealed that those with low levels of radon actually had higher levels of lung cancer than counties with higher levels – where the incidence was lower!
But compare the two maps. The counties with less radon have more lung cancer deaths. EPA’s LNT theory is clearly wrong.
The EPA recommends remediation when radiation measures 4picoCuries per litre of air, but an average adult is naturally radioactive at about 200,000 picoCuries. If the EPA knows this, and they should, why are they concerned about such low, natural radon levels?
The south eastern states had the lowest radon levels, but high cancer rates.
