How Fukushima affected America and what you’re not being told Sally Painter Top Secret Writers 27 Sept 14 http://www.topsecretwriters.com/2014/09/fukushima-affected-america-youre-told/
Have the American people been told the truth about the radiation plumes from the damaged Fukushima plant and ocean contamination? The general public is suspicious and distrustful of the official line concerning the threat of radiation from the Daiichi plant disaster. This is especially worrisome since the Daiichi nuclear plant event has been rated the same Level 7 as the 1986 Soviet Union Chernobyl nuclear plant disaster. Continue reading
“Groundbreaking” study reveals Fukushima nuclear waste is poisoning wildlife: Up to 99% of offspring died after eating ‘low-level’ contaminated food — “Very high” abnormality rates including “severe and rare” deformities (PHOTOS) http://enenews.com/groundbreaking-study-fukushima-radiation-poisoning-wildlife-99-offspring-died-after-eating-food-low-level-contamination-severe-rare-abnormalities-photos?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
PhysOrg, Sep 23, 2014 (emphasis added): In a previous study, the group [of university researchers] suggested that eating leaves with high levels of radiation seriously affected the pale grass blue butterfly. Their new study investigated the effect of eating leaves with much lower levels of radiation… Joji Otaki, University of Rukyus, says… “Our study demonstrated that eating contaminated foods could cause serious negative effects on organisms. Suchnegative effects may be passed down the generations… eating non-contaminated food improves the negative effects”…
AAAS, Sep 22, 2014: Fukushima radiation still poisoning insects — Eating food contaminated with radioactive particles
may bemore perilous than thought… The findings from Otaki’s group are “groundbreaking,” says Timothy Mousseau, a biologist at the University of South Carolina… there have been “almost no studies” on how ingestion of radiation-tainted foods affect wildlife.
Study by University of the Ryukyus and Nagasaki University researchers, published Sep 23, 2014: [We] examined the effects of low-level-contaminated diets… The mortality rate increased linearly in accordance with an increase of the caesium… Remarkably, the mortality rate of the Koriyama group [.04 Bq per larva] was 53% [in the first generation]… We discovered various morphological abnormalities in the surviving adults… severe and rare abnormalities shown in Figure 5might imply the effects of a contaminated diet. Only three [that ate] Okinawa leaves [1760 km from Fukushima Daiichi] showed very minor morphological abnormalities… As observed in the F1 [first] generation, various morphological abnormalities were detected in the surviving F2 [second generation] adults… very high mortality and abnormality rates [were] recorded…low-dose effects were clearly detected… results suggest that low-dose ingestion of approximately 100 Bq/kg may be seriously toxic to certain organisms… The biological effects of ingesting the contaminated diets were more severe in the F2 generation…
- Koriyama [60 km from Fukushima Daiichi] F1 group and the Koriyama F2 group obtained from the Koriyama F1 adults were 53.0% and 79%, respectively
- Motomiya [also 60 km] F1 group and the Motomiya F2 group obtained from the Motomiya F1 adults were 31.2% and 99%, respectively… “very small number of surviving adults”
Prof. Otaki: Many theoreticians and politicians have claimed [that Fukushima has caused] no harmful biological effects… Even worse, some biologists have claimed that there are no biological impacts… to our surprise, leaves contaminated at relatively low levels… resulted in a mortality rate of more than 50%… Moreover, the sensitivity of the offspring generation increased, resulting in very high mortality rates… it is widely believed among modern biologists that insights obtained from one biological system are largely applicable to other systems…
Even Low Radiation Levels In The Fukushima Disaster Area Are Harming Animals http://www.businessinsider.com.au/even-low-radiation-levels-in-the-fukushima-disaster-area-are-harming-animals-2014-9 CHRIS PASH Butterflies eating food collected from around the Fukushima nuclear meltdown site showed higher rates of death and disease, according to a Japanese study.
Researchers fed groups of pale blue grass butterflies (Zizeeria maha) leaves from six different areas at varying distance from the disaster site and then investigated the effects on the next generation.
Feeding offspring the same contaminated leaves as their parents magnified the effects of the radiation.
But offspring fed uncontaminated leaves were mostly like normal butterflies and the authors say this shows that decontaminating the food source can save the next generation.
The 2011 meltdown at the Fukushima Dai-ichi nuclear power plant released substantial amounts of radiation into the surrounding area.
Humans were evacuated and no significant health effects have been reported but the scientists from the University of the Rukyus, Okinawa, are studying the impact on the area’s wildlife.
In a previous study, the group suggested that eating leaves with high levels of radiation seriously affected the pale grass blue butterfly.
Their new study investigated the effect of eating leaves with much lower levels of radiation, which had been collected in 2012, a year after the disaster, from six areas that were between 59kms and 1,760kms from the site.
Their study, published in the journal BMC Evolutionary Biology, showed that even in these comparatively low levels of radiation, there was an observable difference in the butterflies’ lifespan, depending on the dose of caesium radiation in their food. Butterflies fed leaves with higher caesium radiation doses were also smaller and some had morphological abnormalities such as unusually shaped wings.
Professor Joji Otaki, of University of Rukyus, says wildlife has probably been damaged even at relatively low doses of radiation.
He says the study demonstrates that eating contaminated foods can cause serious negative effects on organisms.
“Such negative effects may be passed down the generations,” he says.
“On the bright side, eating non-contaminated food improves the negative effects, even in the next generation.”
Japan Times: Fukushima plant plagued by problems as radioactive material bleeds into Pacific — Radiation level in groundwater now 25,000 times higher than when year began http://enenews.com/japan-times-fukushima-plant-plagued-problems-radioactive-material-bleeds-pacific-record-radiation-level-groundwater-25000-times-higher-when-year-began?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Japan Times, Sept 19, 2014: Tainted water problems still plague Fukushima, despite some positive signs — More than three years since [3/11] the Fukushima No. 1 power plant is still bleeding tons of toxic radioactive water into the Pacific Ocean… [It’s] developed into a wider problem that is stoking public concern… [Tepco] is still trying to find a way to deal with the plant’s utility trenches, which are filled with highly contaminated water. The trenches, which run beneath the plant, were built to house cables and pipes… installed to bring in seawater for cooling purposes… Leaving the tainted water in the trenches is risky. For instance, if another major quake hits and damages the trenches, the toxic water will escape and contaminate the groundwater. Tepco said the trenches… can’t be drained until the leaks from the buildings are plugged…
Asahi Shimbun, Sept 19, 2014: Local fishermen are crying foul over [TEPCO’s] latest plan to discharge processed contaminated water… into the ocean. TEPCO and the central government held the first explanatory briefing… Their explanation was apparently unconvincing. “I can’t believe anything TEPCO says,” one of the attendees said after the meeting… many members of local fisheries associations opposed the plan on the opening day of the briefing sessions… [Others] expressed concern over the plan’s safety. “If a critical problem should occur, (local fisheries) would be severely damaged,” [fisherman Yoshinori Sato] said. “They wouldn’t be able to recover.” Another member criticized the utility for burdening local fishermen with such proposals, asking, “How many times will we have to make a similar painful decision?”
While Japan’s media outlets are focused on the meetings between government/Tepco and the fishermen over the whether to allow ‘processed’ contaminated water releases, new Tepco data published September 18 reveals strontium-90 concentrations are at record levels in groundwater just 100 feet from the ocean. Gross beta has risen to 720 million becquerels per cubic meter (Bq/m³) — and according to Tepco’s most recent strontium-90 tests released September 10 (4 months after the samples were taken), strontium-90 comprises over 95% of the total gross beta at this location — resulting in a Sr-90 concentration of 695 million Bq/m³. At the start of 2014, 28,000 Bq/m³ of gross beta was detected in groundwater from the same well — now 8 months later, the levels are over 25,000 times greater.
Nuclear plant is polluting our drinking water The Mercury, DR. LEWIS CUTHBERT http://www.pottsmerc.com/opinion/20140917/op-ed-nuclear-plant-is-polluting-our-drinking-water 09/16/14, Clean safe water is not a luxury. It’s essential for survival, including personal hygiene, food preparation and cooking. Allowing the intentional destruction of a vital water resource supplying almost 2 million people, for the profit of a multi-billion dollar corporation, is a moral, ethical disgrace. Why should one business, Limerick Nuclear Plant, be permitted to run the Schuylkill River dry and poison it to such a degree that it can become unusable for other businesses and residents?
It is infuriating and unacceptable that our politicians, agency officials, other leaders, and water companies would allow such injustice to continue. Deafening silence continues, while almost two million people from Pottstown to Philadelphia, face a water and public health crisis.
NRC and DEP might as well be working for Exelon.
• Instead of stopping Limerick’s unprecedented threats and harms to the Schuylkill River, NRC plans to relicense Limerick.
• DEP plans to issue an NPDES water pollution permit with dangerous exemptions and loopholes for Limerick’s radiation and cooling tower toxic discharges, and overheating the river.
PA DEP is allowing Limerick to violate federal protective water law and standards. DEP has the power to deny Limerick an NPDES pollution permit renewal. Instead, DEP plans to approve a permit with shocking exemptions. Instead of exemptions from compliance, Exelon, Limerick’s owner, should be required to filter Limerick’s dangerous discharges to meet Safe Drinking Water standards. Exelon is profiting and should be accountable to minimize damage.
Clean water is the law of the land since 1972. Why would PA DEP ignore protective federal clean water laws? Because it saves Exelon the cost of filtration. Governor Corbett appointed Michael Krancer, a former Exelon attorney, to head DEP. Krancer stayed long enough to assure Limerick’s exemption from federal water laws. DEP’s unethical negligence has health and financial consequences.
• Suffering and health care costs will increase. DEP plans to allow unlimited amounts of Limerick’s broad range of radionuclides and toxic cooling tower chemicals to be discharged into the river every day with up to 14.2 million gallons of wastewater.
• It’s cost prohibitive for water companies to monitor or filter Schuylkill River water intake for all Limerick’s cancer causing radionuclides and other toxics.
• Increasing costs to water companies for Limerick’s massive Total Dissolved Solids discharges will ultimately be passed on to their customers. Example: Norristown shut down water distribution for four days recently, resulting in costly plant upgrades. Limerick uses two chemicals that can cause brown water (NPDES Permit).
• Rather than requiring Exelon to slow operations when Limerick discharges overheat the river, DEP plans to eliminate river temperature restrictions that protect aquatic life, public health, and safety.
How can NRC relicense Limerick? There isn’t enough water in the Schuylkill River to sustain daily operations, much less for meltdowns.
• Limerick withdraws over two and a half times more water than the combined withdrawal for Pottstown and Norristown water customers, returning just one quarter to the river. The rest goes into the air as steam from the cooling towers.
• Limerick’s cooling towers depleted the river since the late 1980s. By 1999, DEP reported that it reached record low flows. It’s getting worse. Where you once needed a boat to cross, you can now walk across. Tributaries are even drying up.
If your water is coming from the Schuylkill River through PA American Water, Aqua PA, or your municipality, know your risks. Visitwww.acereport.org. Section #6 “Schuylkill River – Limerick’s Operations Threaten A Drinking Water Disaster” and Video Blogs Updates.
Safe drinking water must be the legacy we leave our children. To save the Schuylkill River and restore an ample, safe water supply for almost two million people and other businesses, Limerick must close. Otherwise, unprecedented threats and harms will increase, expediting a drinking water disaster.
Groups appeal decision in Utah nuclear power plant case By Amy Joi O’Donoghue, Deseret News 17 Sept 14 A consortium of environmental groups are challenging a district court judge’s ruling upholding Utah’s decision to allow more than 53,000 acre-feet of water to be diverted for use in a planned nuclear power plant. SALT LAKE CITY — Environmental groups led by anti-nuclear activists HEAL Utah are challenging a judicial ruling that upheld Utah’s decision to allow Green River water to be used in a proposed nuclear power plant.
The groups contend Utah 7th District Judge George Harmond erred last fall when he upheld a decision by Utah State Engineer Kent Jones granting more than 50,000-acre feet of water for the Blue Castle Holdings plant.
Jones approved the transfer of 50,300 acre-feet of water from the Kane and San Juan County conservancy districts — water that will be ultimately diverted from the Green River in a withdrawal the groups say is not sustainable.
“The Colorado River basin is already over-allocated,” said John Weisheit, conservation director of Living Rivers, one of the groups involved in the lawsuit. “Shortages will likely begin next year for lower basin states and there is a strong chance that hydropower stops at Glen Canyon Dam before this decade is even over.”…..
Opponents to the plant — which is still undergoing the federal licensing process through the U.S. Nuclear Regulatory Commission — also challenged the decision on economic grounds.
“They’ve raised less than 0.1 percent of the total cost of these projects,” said Park City attorney John Flitton of Flitton Babalis, representing the groups.
“What they’re trying to do is get a permit to sell to someone else, and while they wait, they’re tying up water which is increasingly important.”……
Blue Castle Holdings’ president and CEO is Aaron Tilton, a former Utah lawmaker from Utah County who has said his project will withstand judicial scrutiny, meet stringent licensing and safety requirements imposed by federal regulators and provide an alternative, clean source of power for Utah consumers.
The appeal, filed before the Utah State Court of Appeals Wednesday, seeks to unravel those arguments.
“It’s past time for Tilton to admit what we all know — his nuclear scheme is all smoke and no fire,” says Christopher Thomas, HEAL Utah’s executive director. “This project costs too much, uses too much water, and produces expensive power the state doesn’t even want to buy. We hope the Court of Appeals will see that under Utah law, it should not proceed.”
assive Radiation Plume from Fukushima Heading Toward American West Coast According to a Scientific Report By David Gutierrez Global Research, September 11, 2014 According to scientific modeling systems used by the European Union, the radioactive ocean plume released by the 2011 Fukushima nuclear disaster is likely to remain a massive clump of radioactivity until it slams into the West Coast of the United States in late 2017. On March 11, 2011, a massive earthquake and tsunami struck Japan, knocking out power and cooling capability to the Fukushima Daiichi nuclear plant. Within three days, multiple meltdowns and reactor explosions had taken place. By March 25, massive amounts of radioactive material were observed leaking directly into the Pacific Ocean.
In 2013, the Nansen Environmental and Remote Sensing Center in Norway used computer models to project the movement and dispersion of this radioactive plume. Although the results of this study have been cited in official Chinese government documents, they have not been widely publicized.
Levels to remain high through at least 2026
The researchers used two separate scenarios to model leakage of radioactivity from the Fukushima plant into the Pacific. The first scenario assumed continuous and constant leakage for 20 days, while the second assumed continuous and constant leakage for one year.
Although delivering differing estimates of total radiation, both models concluded that the pollution would remain in a relatively unified mass and take the same path across the ocean until crashing up against western North America. Both models show the plume colliding with the U.S. West Coast and beginning to spread out starting around late 2017, with a maximum concentration of radiation hitting the coast toward the end of 2018……..http://www.globalresearch.ca/massive-radiation-plume-from-fukushima-heading-toward-american-west-coast-according-to-a-scientific-report/5401006
One mistake the alternative media analysts are making is that they are confusing the huge amount of radiation presently on site at Fukushima versus the amount that was released from the accident and has since leaked out.
There is no question that the amount of nuclear inventory at Fukushima, a site placed on a weak soil foundation and prone to earthquakes and tsunami, is terrifyingly huge:
The total spent reactor fuel inventory at the Fukushima-Daichi site contains nearly half of the total amount of Cs-137 estimated by the NCRP to have been released by all atmospheric nuclear weapons testing, Chernobyl, and world-wide reprocessing plants (14).
But that material has not yet dispersed, therefore the ocean die-offs now cannot be blamed on harm that could potentially occur in the future. ……….
Great changes in the Earth’s history are marked in geological Ages, with great changes caused by events such as volcanoes, meteorite impacts, climate change and the movement of the Earth’s tectonic plates, and occurring over millions of years. Now geologists are seeing changes in the Earth that are occurring over merely one hundred years.
These changes are caused by the activities of one species – human beings. They usher in a new Age – the Anthropocene (or human-caused ) Epoch.
The changes in the Anthropocene Age are already profound:
- Landscape – Deforestation, desertification, mountains carved by mining, rivers dammed and rerouted, islands sinking under sea level rise.
- Ecology – massive extinctions of species – loss of habitat, loss of biodiversity
- Climate change – rise in greenhouse gases in atmosphere, heating of air and oceans, acidification of oceans, glaciers melting, sea level rise
- Water - shortage of clean drinking water, pollution of groundwater and surface waters.
Those are just a few “headlines” for the changes that we have already wrought on the only liveable planet.
THE NUCLEAR CONTRIBUTION to the Anthropocene Epoch has already been great – with the landscape scarring effect of thousands of atmospheric and underground atomic bomb tests.
Radioactive pollution – from atomic bomb making, and testing, and from several parts of the nuclear power chain has affected soil, groundwater and air.
The nuclear lobby loves to talk about “background radiation” as if it’s all naturally caused and benign. However it includes radionuclides that never before existed on Earth – plutonium, strontium, cesium, carbon-14, and radioactive iodine from atomic bomb testing and other nuclear activities.
Plastic Bags, Nuclear Waste and a Toxic Planet, Energy Collective, Steven Cohen, September 3, 2014 Last week we saw California move a step closer to banning one-time-use plastic bags and the Federal Nuclear Regulatory Commission legalize above-ground storage of nuclear waste. What’s the connection? Every once in a while I think it is useful to turn aside from the deeply rooted, but relatively straightforward problem of climate change, to the growing use of uncontrolled toxic substances in our daily economic life. The toxicity of our environment may well be more difficult to address than the problem of climate change.
The use of toxics in the goods we consume is so widespread that when firefighters enter a modern home that is burning, they must wear breathing devices for protection from the toxicity of the fumes that emanate from our burning floors, appliances, and walls. Household toxics are dangerous, but nothing compared to nuclear waste. Nuclear waste is one of the most toxic substances we have ever fabricated, always bringing to mind the late Barry Commoner’s common sense statement that nuclear power was a “hell of a complicated way to boil water.”………
These bags are an integral component of our throwaway lifestyle, and create major waste management and litter problems throughout the nation. Lightweight plastic bags can be found in the ocean, in trees, and just about everywhere. They are filling up landfills at a rapid rate. We managed to live without them before they were introduced in the 1970s and we’ll probably survive after they are gone; assuming California Governor Jerry Brown signs the bill and California begins yet another national environmental trend.
While we see progress on the coast, we remain mired in toxic waste back in the nation’s capital. The problem is that our broken political process is incapable of dealing with the nuclear waste that is accumulating at the nation’s civilian nuclear power plants. …….
In order to allow plants to be licensed again, the Nuclear Regulatory Commission decided that nuclear waste could now be stored indefinitely in well-guarded and well-maintained above ground storage facilities. Scientists estimate that some nuclear waste will remain toxic for hundreds of thousands of years. In fact, one of the reasons for below ground storage was the likelihood that the repository would last longer than our current civilization.
Many of my climate change-oriented colleagues argue that nuclear power is a realistic and desirable replacement for fossil fuels. But any close look at the technical and political problems of nuclear waste should provide ample reason to look elsewhere for a solution to our energy needs. ………..
Our economy is filled with a range of substances and products that have been engineered without much thought given to long term environmental impacts. Our houses and fences were once made of wood, a fairly traditional and very biodegradable material that literally grows on trees. Today vinyl and other plastics that last longer and are easier to maintain have replaced wood in homes all over America. Many of our consumer products are far from biodegradable; some include toxics and many are designed for planned obsolescence. These ordinary, mundane products are entering our waste stream and finding their way into fragile, interconnected ecosystems all over the planet. Sometimes the impact is minor, sometimes it is significant, but generally it is unexamined, careless and casual.
From ordinary plastic bags to extraordinary pools of nuclear waste, we have unleashed a staggering array of poisons into the same ecosystems that feed us and provide us with other biological necessities such as air and water. In some cases, such as nuclear waste, we have heard decades of discussion and debate about risks, costs and benefits. However in most cases, we are either ignorant or barely aware of the impacts and potential risks…….
Radioactive Boars From Chernobyl Are Still Wandering Around Germany, Sarah Zhang, http://www.gizmodo.com.au/2014/09/radioactive-boars-from-chernobyl-are-still-wandering-around-germany/4 Sept 14 Nearly 30 years later, radiation from Chernobyl still scars the landscape. Perhaps most remarkably, some of that radiation travelled hundreds of kilometres downwind, settled into the soil, and moved up through the food chain. So now we have radioactive wild boars, still roaming around Germany causing trouble.
Since 2012, according to the Telegraph, the state government of Saxony has required that boars hunted for food be tested for radiation. One in three regularly exceeds the safety limit. How did wild boars born decades after the Chernobyl disaster become radioactive? The Telegraph explains:
Even though Saxony lies some 700 miles from Chernobyl, wind and rain carried the radioactivity across western Europe, and soil contamination was found even further away, in France.
Wild boar are thought to be particularly affected because they root through the soil for food, and feed on mushrooms and underground truffles that store radiation. Many mushrooms from the affected areas are also believed to be unfit for human consumption.
Wild radioactive boars may be dangerous to eat, but wild boars in general are a menace across Germany. They’re digging up gardens, shutting down the Autobahn, and even attacking the occasional poor soul. Read more about the boars at the Telegraph.
Fukushima forecast used by gov’t shows nuclear waste crossing ocean in single massive cluster — “Maximum concentration propagates eastward in Pacific toward U.S.” — Highest levels worldwide remain along coast of N.

Nansen Environmental and Remote Sensing Center (Norway), 2013 (emphasis added): The massive nuclear leakage into ocean from Fukushima Nuclear Power Plant was observed on March 25th,2011. The transport of leaked radioactive pollutant from the Fukushima Nuclear Power Plant was simulated… assuming constant and continuous leakage for 20 days (scenario 1) and for one year(scenario 2) starting from March 25th, 2011 and was integrated for 20 years… There is no remarkable difference of transport pathways… for the nuclear waste… The results of the ensembles indicate that the nuclear pollutant for both scenarios transports eastward to eastern Pacific… It takes about 10 to 15 years to reach the coast of East Asia… a realistic sourcefunction is required and atmospheric fallout and role of ocean ecology should also be taken into account, in order to get a more reliable assessment of possible impact of the radioactive leakage on the ocean environment.
Nansen Environmental and Remote Sensing Center, Prof. Ola Johannessen, University of Bergen Geophysical Institute: Ocean spreading of radioactivity from the Fukushima nuclear plant in Japan [...] The results show that the maximum concentration propagates eastward in the Pacific toward the United States during a 7-year period while the total concentration drops to 1-2% of the source concentration (100%) after 5 years.

Radiological Disaster Survey in Tokyo Suburbs: 13μSv/h in Kashiwa, Chiba http://fukushimaemergencywhatcanwedo.blogspot.com.au/2014/08/radiological-disaster-survey-in-tokyo_26.html 2014-08-24 osted by dunrenard According to Ministry of Education, Culture, Sports, Science and Technology, the radiation level (gamma ray) in Tokyo was 0.036 μSv/h before 311. And now with the Japan fukushima nuclear contamination Tokyo 13μSv/h.
13μSv/h is 388 times more than what the Tokyo government measures at Shinjuku, 176 times more than their measurement in Edogawa-ku.
Here is what the Tokyo government finds at their (concrete and metal) monitoring posts (some of which are conveniently located 23 meters above ground):

Studies are revealing the impact that low-dose exposure to radiation is having on plants and animals after the Fukushima disaster in 2011. Biologists commenced research just a few months after the nuclear accident, now three years later the studies have been published in the Journal of Heredity. The research shows the genetic mutations and population declines that are occurring in a variety of non-human organisms.
“A growing body of empirical results from studies of birds, monkeys, butterflies, and other insects suggests that some species have been significantly impacted by the radioactive releases related to the Fukushima disaster,” Timothy Mousseau from the University of South Carolina in the US, who led one of the studies, explained in a press release.
All of the studies indicate that low-dose exposure to ionising radiation (the kind caused by the Fukushima meltdown) leads to increased mutation and genetic damage to both reproductive and non-reproductive cells.
Studies on this pale grass blue butterfly (pictured above) show slowed growth, reduction in size, higher mortality and abnormalities in butterflies from the affected areas and in their offspring. The butterfly on the left is suffering from mutations that stop it from escaping from its own cacoon.
“Detailed analyses of genetic impacts to natural populations could provide the information needed to predict recovery times for wild communities at Fukushima as well as any sites of future nuclear accidents,” Mousseau said in a press release. “There is an urgent need for greater investment in basic scientific research of the wild animals and plants of Fukushima.”
New study finds radiation dose for US West Coast from Fukushima over 500% of recent gov’t estimate Fukushima Emergency What Can We Do Release from Japan disaster could exceed Chernobyl
Atmospheric transport and deposition of radionuclides released after the Fukushima Dai-chi accident and resulting effective dose, Atmospheric Environment, Sept. 2014 (emphasis added): On 11 March 2011 an earthquake off the Pacific coast of the Fukushima prefecture generated a tsunami that hit Fukushima Dai-ichi and Fukushima Da-ini Nuclear Power Plants. From 12 March a significant amount of radioactive material was released into the atmosphere and dispersed worldwide. [...] The simulation shows that the radioactive plume, consisting of about 200 PBq by adding contributions from 131I, 134Cs, and 137Cs, has been transported over the entire northern hemisphere[...] An early quantitative estimation of the amount of radioactive material discharged in the atmosphere has been provided by Chino et al. (2011) by coupling environmental monitoring data with atmospheric dispersion simulations, then updated by Katata et al. (2012) with a more detailed description of the emission from the morning of 12 March to late night of 14 March. The total amount of radioactivity has been estimated in 12.6 PBq of 134Cs and 137Cs, and 128.2 PBq of 1311. [...] The uncertainty associated with this source term has been estimated by Chino et al. (2011)to be a factor of 5 or greater.
- As the study notes “uncertainty associated with this source term has been estimated… to be a factor of 5or greater.” Using only a factor of 5, the result is 63 PBq of 137Cs (5 x 12.6) and 63 PBq of 134Cs (5 x 12.6) released at Fukushima — 126 PBq total.
- According to an estimate by the National Academy published in 1995, “35 PBq of Cs-134 and 70 PBq of Cs-137 were released” at Chernobyl — 105 PBq total…………http://fukushimaemergencywhatcanwedo.blogspot.com.au/2014/08/new-study-finds-radiation-dose-for-us.html
