” My recent post on the spread of radiation stemming from the Fukushima nuclear accident drew quite a few questioning comments. Specifically the article suggested that radiation from the accident was drifting across the Pacific at levels high enough to cause alarm. It turns out such cause for alarm was exaggerated, though there is still reason to be concerned. I appreciate the feedback. I acknowledge that I relied on sources with which I was unfamiliar and posted some information that has been shown to be incorrect. I apologize.
To all who publish online, beware. Bad news travels fast. It gives credence to the old saying, “A lie can travel halfway around the world while the truth is still putting its pants on.” This is especially true on the Internet. I truly hope no one was harmed by this information. Now begins the task of earning back your trust which, though hard-earned, can be quickly lost.
I think the best way to start is to post a revised story on what is actually happening in the waters around Fukushima, Japan, as well as those farther afield.
For starters the initial source, PeakOil, used a bogus NOAA graphic to sensationalize the story, having carefully scrubbed out the legend showing that the colors actually represented wave heights at the peak of the tsunami, not radiation levels as the site would have you believe. I checked this image out, noticed this and chose not to use it in my post. Still, I continued to take the central thrust of the story as true.
Several people went to the generally reliable Snopes site to question the story and found confirmation of their suspicions. The blatant misuse of the NOAA chart is clearly called and tossed into the trash where it belongs. An interesting thing about the Snopes post, however, is that while the site prominently displays a text clipping stating that, “each day 300 tons of radioactive waste seeps into the ocean,” it never specifically addresses that claim.
I dug further and found that number actually comes from a quote by Yushi Yoneyama, an official with the Japanese Ministry of Economy, Trade and Industry, which oversees energy policy as quoted in Reuters (generally considered unassailable) and elsewhere. In 2013, Yoneyama said, “We think that the volume of water [leaking into the Pacific] is about 300 tonnes a day.” Of course, anyone could be wrong, but who am I to question Reuters or a Japanese government official? I don’t.
That’s not to say Japanese government officials, or officers of TEPCO, can always be counted on to tell the truth, but their interest has generally been to minimize the extent of the damage, not to embellish it.
As for that amount of leakage, that’s equivalent to about 90,000 gallons of radioactive water. That sounds like quite a bit. But compared to the volume of the Pacific Ocean, it’s not a lot at all. Still, when that much leaks out each day, over the course of a year, it adds up to 33 million gallons. And it’s been five years now.
Even today, TEPCO only acknowledges that radioactive water threatens to flood out of the plant and into the ocean. The company denied, until recently, that any water leaked from the plant at all, even when fish contaminated with high levels of radiation were found near the plant by independent researchers from the University of Tokyo, raising major concerns for local fishermen.
The story regarding radiation reaching the Canadian West Coast, which claimed levels of iodine-131 were 300 times background levels, was recently updated with an editor’s statement that the original figures were incorrect.
Reports of a wildlife biologist (Alexandra Morton) pulling hundreds of herring out of the waters off British Columbia with blood coming out of their eyes and gills have not been discredited. However, there is no evidence linking this observation directly to radiation from Fukushima or anywhere else.
The claim that radiation levels found in tuna off the Oregon coast had tripled also appears to be legitimate. However, those levels are still substantially below what would be considered a health threat.
Having sorted through that, I would summarize as follows: Contaminated water continues to enter to ocean from the Fukushima site in significant volume. Traces of radiation have been found in various locations around the Pacific. It also appears that the levels detected at this time do not indicate any immediate threat to humans outside of Japan. That being said, our knowledge of the long-term impacts of these types of radiation on the oceans, and on ourselves, is far from complete.
Upon review, most of the statements in the original piece were in fact true, but I acknowledge the overall sense was that of an exaggerated cause for concern. What this shows is how easily a group of facts taken out of context can become a convincing story — a lesson for all of us. Putting it on the Internet is like putting a match to a dry grassland.
What is far less clear is what the actual levels are and where they can be found. What makes writing about this issue so difficult, and even dangerous, is the combination of two things: It’s a frightening subject, and there is very little solid information being made available.
In my efforts to bring in some more solid facts, I reached out to Greenpeace, which is monitoring the situation carefully. The group sent me some additional information in a press release with links to reports published outside the U.S.
Greenpeace’s famed ship, the Rainbow Warrior, went out to sample the waters around Fukushima in February of this year with former Japanese Prime Minister Mr. Naoto Kan onboard. What they found was that radiation in the seabed off Fukushima “is hundreds of times above pre-2011 levels.” They also found levels in nearby rivers that were “up to 200 times higher than ocean sediment.”
Expressing concern, Ai Kashiwagi, energy campaigner for Greenpeace Japan, said: “These river samples were taken in areas where the Abe government is stating it is safe for people to live. But the results show there is no return to normal after this nuclear catastrophe.”
The areas sampled include the Niida River in Minami Soma, where readings measured as high as 29,800 becquerels per kilogram (Bq/kg) for radio-cesium. (For those new to the subject, a becquerel is a derived unit that measures radioactivity.) More samples taken at the estuary of the Abukuma River in Miyagi prefecture, more than 90 kilometers north of the Fukushima Daiichi plant, found levels in sediment as high as 6,500 Bq/kg. To put that in perspective, recorded levels in the seabed near the plant before the disaster were 0.65 Bq/kg.
Kendra Ulrich, senior global energy campaigner for Greenpeace Japan, explained: “The sheer size of the Pacific Ocean combined with powerful complex currents means the largest single release of radioactivity into the marine environment has led to the widespread dispersal of contamination.”
Greenpeace expressed concern that the order scheduled to allow people to return to these areas next March “cannot be permitted to stand.” The group claims that “these ecosystems cannot simply be decontaminated.”
Greenpeace’s report, which came out in July of this year, concludes by saying the impact of the accident will persist for “decades to centuries.”
So, while we have not yet seen the global-scale consequences some predicted, the situation is indeed bad and getting worse. TEPCO continues to build steel tanks at the rate of three per week, to house a great deal of contaminated groundwater while awaiting decontamination. But according to this PBS documentary, the company will run out of room for more tanks sometime next year. The gravity-fed water filtration system has been effective in removing most contaminants, except for tritium. Tritium is a relatively weak radionuclide with a half-life of 12.5 years, which means it will take about 100 years to fully break down.
The molten nuclear cores in reactors still remain in three reactors. And the site will not be fully stabilized until those are removed. But the radioactivity level in those reactors is far too high for people to enter. TEPCO plans to develop robots to go in and retrieve the molten fuel. The company says that retrieval is estimated to begin in 2020.
In closing, while the level of concern suggested in the prior piece was overstated, I maintain that the situation at Fukushima is far from resolved and that it remains a serious concern, particularly in Japan. I further maintain that any plans to continue expanding nuclear power must include an in-depth review of what has happened in Fukushima, with the understanding that this story is far from over. ”
” Nuclear power may never recover its cachet as a clean energy source, irrespective of safety concerns, because of the ongoing saga of meltdown 3/11/11 at Fukushima Daiichi Nuclear Power Plant. Over time, the story only grows more horrific, painful, deceitful. It’s a story that will continue for generations to come.
Here’s why it holds pertinence: As a result of total 100% meltdown, TEPCO (Tokyo Electric Power Company) cannot locate or remove the radioactive molten core or corium from the reactors. Nobody knows where it is. It is missing. If it is missing from within the reactor structures, has it burrowed into the ground? There are no ready answers.
And, the destroyed nuclear plants are way too radioactive for humans to get close enough for inspection. And, robotic cameras get zapped! Corium is highly radioactive material, begging the question: If it has burrowed through the containment vessel, does it spread underground, contaminating farmland and water resources and if so, how far away? Nobody knows?
According to TEPCO, removing the melted cores from reactors 1,2 and 3 will take upwards of 20 years, or more, again who knows.
But still, Japan will hold Olympic events in Fukushima in 2020 whilst out-of-control radioactive masses of goo are nowhere to be found. TEPCO expects decades before the cleanup is complete, if ever. Fortunately, for Tokyo 2020 (the Olympic designation) radiation’s impact has a latency effect, i.e., it takes a few years to show up as cancer in the human body.
A week ago on September 7th, Former PM Junichiro Koizumi, one of Japan’s most revered former prime ministers, lambasted the current Abe administration, as well as recovery efforts by TEPCO. At a news conference he said PM Shinzō Abe lied to the Olympic committee in 2013 in order to host the 2020 Summer Olympics in Japan.
“That was a lie,” Mr Koizumi told reporters when asked about Mr Abe’s remark that Fukushima was “under control,” Abe Lied to IOC About Nuke Plant, ex-PM Says, The Straits Times, Sep 8, 2016. The former PM also went on to explain TEPCO, after 5 years of struggling, still has not been able to effectively control contaminated water at the plant.
According to The Straits Times article: “Speaking to the IOC in September 2013, before the Olympic vote, PM Abe acknowledged concerns but stressed there was no need to worry: “Let me assure you, the situation is under control.”
PM Abe’s irresponsible statement before the world community essentially puts a dagger into the heart of nuclear advocacy and former PM Koizumi deepens the insertion. After all, who can be truthfully trusted? Mr Koizumi was a supporter of nuclear power while in office from 2001-2006, but he has since turned into a vocal opponent.
Speaking at the Foreign Correspondents Club of Japan in Tokyo, Mr Koizumi said: “The nuclear power industry says safety is their top priority, but profit is in fact what comes first… Japan can grow if the country relies on more renewable energy,” (Ayako Mie, staff writer, Despite Dwindling Momentum, Koizumi Pursues Anti-Nuclear Goals, The Japan Times, Sept. 7, 2016).
Mr Koizumi makes a good point. There have been no blackouts in Japan sans nuclear power. The country functioned well without nuclear.
Further to the point of nuclear versus nonnuclear, Katsunobu Sakurai, mayor of Minamisoma, a city of 70,000 located 25 km north of Fukushima No. 1 nuclear plant, at a news conference in Tokyo, said: “As a citizen and as a resident of an area affected by the nuclear power plant disaster, I must express great anger at this act… it is necessary for all of Japan to change its way of thinking, and its way of life too – to move to become a society like Germany, which is no longer reliant on nuclear power,” (Sarai Flores, Minamisoma Mayor Sees Future for Fukushima ‘Nonnuclear’ City in Energy Independence, The Japan Times, March 9, 2016).
In March of 2015, Minamisoma declared as a Nonnuclear City, turning to solar and wind power in tandem with energy-saving measures.
Meanwhile, at the insistence of the Abe administration, seven nuclear reactors could restart by the end of FY2016 followed by a total of 19 units over the next 12 months (Source: Japanese Institute Sees 19 Reactor Restarts by March 2018, World Nuclear News, July 28, 2016).
Greenpeace/Japan Discovers Widespread Radioactivity
One of the issues surrounding the Fukushima incident and the upcoming Olympics is whom to trust. Already TEPCO has admitted to misleading the public about reports on the status of the nuclear meltdown, and PM Abe has been caught with his hand in the proverbial cookie jar, but even much worse, lying to a major international sports tribunal. His credibility is down the drain.
As such, maybe third party sources can be trusted to tell the truth. In that regard, Greenpeace/Japan, which does not have a vested interest in nuclear power, may be one of the only reliable sources, especially since it has boots on the ground, testing for radiation. Since 2011, Greenpeace has conducted over 25 extensive surveys for radiation throughout Fukushima Prefecture.
In which case, the Japanese people should take heed because PM Abe is pushing hard to reopen nuclear plants and pushing hard to repopulate Fukushima, of course, well ahead of the 2020 Tokyo Olympics since there will be events held in Fukushima Prefecture. After all, how can one expect Olympians to populate Fukushima if Japan’s own citizens do not? But, as of now to a certain extent citizens are pushing back. Maybe they instinctively do not trust their own government’s assurances.
But, more chilling yet, after extensive boots-on-the-ground analyses, Greenpeace issued the following statement in March 2016: “Unfortunately, the crux of the nuclear contamination issue – from Kyshtym to Chernobyl to Fukushima- is this: When a major radiological disaster happens and impacts vast tracts of land, it cannot be ‘cleaned up’ or ‘fixed’.” (Source: Hanis Maketab, Environmental Impacts of Fukushima Nuclear Disaster Will Last ‘decades to centuries’ – Greenpeace, Asia Correspondent, March 4, 2016).
That is a blunt way of saying sayonara to habitation on radioactive contaminated land. That’s why Chernobyl is a permanently closed restricted zone for the past 30 years.
As far as “returning home” goes, if Greenpeace/Japan ran the show rather than PM Abe, it appears they would say ‘no’. Greenpeace does not believe it is safe. Greenpeace International issued a press release a little over one month ago with the headline: Radiation Along Fukushima Rivers up to 200 Times Higher Than Pacific Ocean Seabed – Greenpeace Press Release, July 21, 2016.
Here’s what they discovered: “The extremely high levels of radioactivity we found along the river systems highlights the enormity and longevity of both the environmental contamination and the public health risks resulting from the Fukushima disaster,” says Ai Kashiwagi, Energy Campaigner at Greenpeace Japan.
“These river samples were taken in areas where the Abe government is stating it is safe for people to live. But the results show there is no return to normal after this nuclear catastrophe,” claims Kashiwagi.
“Riverbank sediment samples taken along the Niida River in Minami Soma, measured as high as 29,800 Bq/kg for radiocaesium (Cs-134 and 137). The Niida samples were taken where there are no restrictions on people living, as were other river samples. At the estuary of the Abukuma River in Miyagi prefecture, which lies more than 90km north of the Fukushima Daiichi plant, levels measured in sediment samples were as high as 6,500 Bq/kg” (Greenpeace).
The prescribed safe limit of radioactive cesium for drinking water is 200 Bq/kg. A Becquerel (“Bq”) is a gauge of strength of radioactivity in materials such as Iodine-131 and Cesium-137 (Source: Safe Limits for Consuming Radiation-Contaminated Food, Bloomberg, March 20, 2011).
“The lifting of evacuation orders in March 2017 for areas that remain highly contaminated is a looming human rights crisis and cannot be permitted to stand. The vast expanses of contaminated forests and freshwater systems will remain a perennial source of radioactivity for the foreseeable future, as these ecosystems cannot simply be decontaminated” (Greenpeace).
Still, the Abe administration is to be commended for its herculean effort to try to clean up radioactivity throughout Fukushima Prefecture, but at the end of the day, it may be for naught. A massive cleanup effort is impossible in the hills, in the mountains, in the valleys, in the vast forests, along riverbeds and lakes, across extensive meadows in the wild where radiation levels remain deadly dangerous. Over time, it leaches back into decontaminated areas.
And as significantly, if not more so, what happens to the out-of-control radioactive blobs of corium? Nobody knows where those are, or what to do about it. It’s kinda like the mystery surrounding black holes in outer space, but nobody dares go there.
Fukushima is a story for the ages because radiation doesn’t quit. Still, the Olympics must go on, but where? ”

” CHIBA – The government on Friday informed the city of Chiba that the radioactive designation for 7.7 tons of Fukushima-tainted waste stored in the city will be lifted on Saturday, allowing it to be treated as general garbage.
State Minister of the Environment Shinji Inoue conveyed the decision to Chiba Mayor Toshihito Kumagai during a meeting at City Hall in Chiba Prefecture’s capital.
The decision came after it was found that the radioactive activity of cesium in the waste had fallen below the state-set limit of 8,000 becquerels per kilogram.
It will be the first time for such a designation to be lifted for such waste.
The waste was part of the aftermath of the massive earthquake and subsequent tsunami of March 2011, which triggered a triple core meltdown at the Fukushima No. 1 power plant. The defunct plant is owned by Tokyo Electric Power Holdings Inc.
Some 3,700 tons of designated radioactive waste created by the man-made meltdowns, including incineration ash, is stored in Chiba. The 7.7 tons in question is sitting in a garbage disposal facility in Mihama Ward in Chiba.
The lifting of the designation will allow the city to dispose of the waste in the same way as general waste. But Kumagai has expressed his intention to keep it in storage for the time being.
As of the end of March, 172,899 tons of such designated waste was being stored in Chiba, Tokyo and 10 other prefectures in eastern Japan. ”
” New research shows that most of the radioactive fallout which landed on downtown Tokyo a few days after the Fukushima accident was concentrated and deposited in non-soluble glass microparticles, as a type of ‘glassy soot’. This meant that most of the radioactive material was not dissolved in rain and running water, and probably stayed in the environment until removed by direct washing or physical removal. The particles also concentrated the radioactive caesium (Cs), meaning that in some cases dose effects of the fallout are still unclear. These results are announced at the Goldschmidt geochemistry conference in Yokohama, Japan.
The flooding of the Fukushima Daiichi Nuclear Power Plant (FDNPP) after the disastrous earthquake on March 11 2011 caused the release of significant amounts of radioactive material, including caesium (Cs) isotopes 134Cs (half-life, 2 years) and 137Cs (half-life, 30 years).
Japanese geochemists, headed by Dr Satoshi Utsunomiya (Kyushu University, Japan), analysed samples collected from within an area up to 230 km from the FDNPP. As caesium is water-soluble, it had been anticipated that most of the radioactive fallout would have been flushed from the environment by rainwater. However, analysis with state-of-the-art electron microscopy in conjunction with autoradiography techniques showed that most of the radioactive caesium in fact fell to the ground enclosed in glassy microparticles, formed at the time of the reactor meltdown.
The analysis shows that these particles mainly consist of Fe-Zn-oxides nanoparticles, which, along with the caesium were embedded in Si oxide glass that formed during the molten core-concrete interaction inside the primary containment vessel in the Fukushima reactor units 1 and/or 3. Because of the high Cs content in the microparticles, the radioactivity per unit mass was as high as ~4.4×1011 Bq/g, which is between 107 and 108 times higher than the background Cs radioactivity per unit mass of the typical soils in Fukushima.
Closer microparticle structural and geochemical analysis also revealed what happened during the accident at FDNPP. Radioactive Cs was released and formed airborne Cs nanoparticles. Nuclear fuel, at temperatures of above 2200 K (about as hot as a blowtorch), melted the reactor pressure vessel resulting in failure of the vessel. The airborne Cs nanoparticles were condensed along with the Fe-Zn nanoparticles and the gas from the molten concrete, to form the SiO2 glass nanoparticles, which were then dispersed.
Analysis from several air filters collected in Tokyo on 15 March 2011 showed that 89% of the total radioactivity was present as a result of these caesium-rich microparticles, rather than the soluble Cs, as had originally been supposed.
According to Dr Satoshi Utsunomiya;
“This work changes some of our assumptions about the Fukushima fallout. It looks like the clean-up procedure, which consisted of washing and removal of top soils, was the correct thing to do. However, the concentration of radioactive caesium in microparticles means that, at an extremely localized and focused level, the radioactive fallout may have been more (or less) concentrated than anticipated. This may mean that our ideas of the health implications should be modified”.
Commenting, Prof. Bernd Grambow, Director of SUBATECH laboratory, Nantes, France and leader of the research group on interfacial reaction field chemistry of the ASRC/JAEA, Tokai, Japan, said:
“The leading edge observations by nano-science facilities presented here are extremely important. They may change our understanding of the mechanism of long range atmospheric mass transfer of radioactive caesium from the reactor accident at Fukushima to Tokyo, but they may also change the way we assess inhalation doses from the caesium microparticles inhaled by humans. Indeed, biological half- lives of insoluble caesium particles might be much larger than that of soluble caesium”. ”

Read a similar article by SimplyInfo that sheds more light on the radioactive fallout from Fukushima Daiichi.
” FUKUSHIMA–Highly radioactive soil that should by law be removed by the central government has been left dumped in the corner of a schoolyard here because the construction of a local storage site for waste has been stalled.
Students at the school were not given an official warning that the radioactive soil was potentially hazardous to their health.
When a teacher scooped up soil samples at the site and had their radiation levels measured by two nonprofit monitoring entities–one in Fukushima and another in Tokyo–the results showed 27,000-33,000 becquerels of radioactive cesium per kilogram.
The law stipulates that the central government is responsible for disposing of waste measuring more than 8,000 becquerels per kilogram.
But as a central government project to build an interim storage site for highly radioactive waste near the nuclear power plant has been stalled, the school appears to have no alternative to indefinitely keeping it in the schoolyard.
Principal Seiichi Takano at Fukushima North High School said the school does not plan to take extra safety measures with regard to the storage of the polluted dirt, saying the waste is not believed to be outright dangerous.
“The prefectural board of education has not set any criteria for us to conclude at what levels of radiation are hazardous to people,” he said.
The fallout is a result of the nuclear disaster at the Fukushima No. 1 power plant, which unfolded following the Great East Japan Earthquake and ensuing tsunami on March 11, 2011.
Before the cleanup operation at the school in the city’s Iizaka district on May 24-25, the teacher who took the samples called on school officials to take precautionary measures and issue an alert for students.
“Since it is highly radioactive, we should remind students and staff of the potential danger while taking a step to prevent the spread of polluted dust during cleanup,” said the teacher.
Highly radioactive dirt, which was mixed with tree branches and plants, amounted to 20 cubic meters, according to cleanup workers. It had been left for several years in an area near the parking lot for bicycles used by students.
School officials say they plan to bury the bags by digging deep holes on the school premises to temporarily store them, but they have no idea when they will finally be removed.
The polluted dirt in the latest cleanup first came to the attention of school officials in March when a preliminary survey detected 1.6 microsieverts per hour of radiation at a point 1 meter from the surface of the ground near the bicycle parking lot. The survey is routine before any cleanup gets under way in earnest.
A cleanup operation is conducted with the aim of lowering radiation exposure to below 0.23 microsieverts per hour, a long-term goal the central government has set to limit residents’ annual additional exposure to a maximum of 1 millisievert.
In the previous decontamination operation, the school’s playground was cleaned in August 2011 before classes were resumed for that academic year after a break after the nuclear accident.
A large amount of contaminated soil–far more radioactive than in the current incident–is still buried in the schoolyard for temporary storage.
Cleanup resumed only this spring for the rest of the school premises and its neighborhood in line with a general cleanup plan in Fukushima.
An official with the prefectural board of education said it is not considering additional safety measures concerning the storage of polluted soil kept at the school.
“We are going to ensure safety by taking an approach similar to the existing one before the polluted soil is transported to the interim storage facility,” said a board official. ”
