New Public TV Documentary on Fukushima: Meltdown: Cooling Water Crisis

Nukewatch Quarterly Summer 2020

A March report by Greenpeace Japan, “Radioactivity on the Move 2020,” is a stark reminder of the daunting and endless radiation hazards caused by the triple reactor meltdown of 2011 at the Fukushima-Daiichi complex.

In Fukushima Prefecture, spring snow melt and heavy rains remobilize stocks of radio-cesium in forests, hill slopes, and floodplains that were heavily contaminated by the radiation disaster, and that then contaminate areas downstream—frustratingly, even areas that were already decontaminated. “… as a result of the contamination in 2011, these uphill forests serve as a long-term source of radioactivity for the areas below. The principle radioactive source, cesium-137, has a half-life of 30 years, and therefore will remain a hazard for around ten half-lives, or 300 years.

Conducted soon after the October 2019 Typhoon Hagibis, which was one of the most powerful typhoons in 100 years, the group’s survey “observed concentrated radiation levels throughout Fukushima Prefecture, including significant radiation hotspots….” Building on its 2016 report “Radiation Reloaded,” Greenpeace’s extensive radiation survey raises alarms about the re-contamination caused by Hagibis, “which released radioactive cesium [downhill] from the forested mountains of Fukushima prefecture which make up 70% of the region, and which cannot feasibly be decontaminated.”

The report paints an accusatory picture of Japan’s government, “Which continues to push its propaganda of normalization in Fukushima,” in order to convince the public in general and evacuees in particular that it is safe to return to their houses. The report notes that “the Japanese government remains committed to policies which aim to pressure tens of thousands of Japanese Internally Displaced Persons  to return to their former homes.”

The government’s resettlement push is also motivated by the huge economic investment in hosting the postponed summer Olympics. The games have been put off until July 23, 2012, not because of the radioactive dangers documented and presented to the government by Greenpeace Japan, but because of the coronavirus pandemic.

One example of the government’s recklessness, is its arbitrary setting of radiation exposure allowances. Global standards for radiation exposure are set by the International Commission on Radiation Protection, and the maximum exposure for the general public in Japan was one (1) milliSievert per year (mSv/y) until 2012.

But in April 2012, the government increased the maximum annual exposure twenty-fold, to 20 milliSieverts per year (20 mSv/y). This eye-popping increase of allowable exposure applies across-the-board to infants and children, while girls and women are all known to be more vulnerable to the harmful effects of radiation than adult men. Greenpeace says this was done “as part of its strategy to lift evacuations orders.”

The typhoon’s recontamination and resulting levels of potential radiation exposure have caused a “… radiological situation in Fukushima prefecture, specifically in both the open and exclusion zones of Namie, Iitate, and Okuma, [that] leads Greenpeace Japan to conclude that levels remain too high for the safe return of thousands of evacuees to these areas,” the report says. “Namie, Iitate, Okuma and Futaba remain highly contaminated.”

In its consideration of areas where evacuation orders have already been lifted, the report is highly critical. “Japanese government maintains that exposure to 20 mSv/y is acceptable in these lifted evacuation order areas. This is despite clear scientific evidence of the cancer risks from low dose radiation exposure in the 1-5 mSv/y range, which the Japanese government continues to disregard.”

Decontamination efforts have been a large part of the government’s strategy of returning people to areas hit with radioactive fallout. Yet decontamination has been less effective around houses located close to hillside forests, “where decontamination is not possible.”  Unfortunately, the report notes, “radioactivity from the non-decontaminated forest might re-contaminate the already decontaminated area below and closer to houses.”

In addition, radioactive particles and organic matter carried down from forests and fields with heavy rains and typhoons “will create continuing, subsequent influxes of radio-cesium in lakes and coastal ecosystems for years and decades to come,” the report notes. “In particular, typhoons cause significant increases in cesium discharges into the Pacific Ocean.”

The survey also discovered high levels of radiation and multiple radiation “hotspots” in Fukushima City, the J-Village sports complex and along the route of the Olympic Torch run. These findings directly challenge the government’s “propaganda narrative” leading up to the Olympic Games, and endanger athletes and everyone else involved with the games.

Nukewatch Quarterly Summer 2020

Here’s a good one. In 2011, at the time of the tsunami and the Fukushima triple reactor meltdowns and explosions, the nuclear-powered aircraft carrier USS Ronald Reagan was about 60 miles off the coast of Japan. The ship was directed to lend assistance in what was called Operation Tomodachi (friendship)—to provide assistance. What no one on board was told was that the reactors had exploded and a plume of highly radioactive material was blowing east from the site into the path of the vessel. Of course, when it was doused, all the radiation monitors on the carrier started screaming, and returning planes and helicopters that had flown support sorties were contaminated.

In 2014, I was engaged by some California attorneys to advise them in a law suit brought against Japan’s Tokyo Electric Power Co. and the US against reactor builder General Electric on behalf of sailors who served on the carrier. A significant number of the Ronald Reagan crew was reporting a wide range of weird illnesses including cancers, all of which they attributed to their service-related radiation exposure. Between 2014 and now, the court arguments were all about procedure, and about whether the case should be heard in Japan or in the vessel’s home port of San Diego, California. There was a lot of publicity[1]. Recently, a California judge decided that the case had to be heard in Japan. This is grossly unjust since Japanese and US law differs, and the sailors cannot afford to go to Japan or to hire Japanese lawyers, but not the focus of this report.

In 2014, following all the publicity about the cancers, a number of US Senators and others asked pertinent questions, and the Navy had to do something to answer the accusations that Fukushima radiation was killing those who sailed on Operation Tomodachi. It panicked. A big report was prepared by the US Defense Threat Reduction Agency (DTRA), entitled: “Final Report to the Congressional Defense Committees in Response to the Joint Explanatory Statement Accompanying the Department of Defense Appropriations Act,” 2014, page 90, “Radiation Exposure”[2]. Never use one word when ten will do.

This report rambled on about how low the Fukushima doses were, how everyone acted wonderfully, and how all the radioactivity was rapidly cleaned up. The “dose reconstruction” showed that no one got more than a fraction of the “natural background” dose, and so forth. (The methodology for the dose reconstruction has since disappeared from the link given in the report.) But to prove that there were no excess cancers on the Ronald Reagan, the Navy took a step too far. It reported the results of its own epidemiological study which it carried out on the Ronald Reagan sailors. This study compared the illness yield (including cancers) of the 4,843 Ronald Reagan sailors with a matched control group of 65,269 sailors on US Navy nuclear-powered ships that were not anywhere near Fukushima. The period of analysis was from 2011 to 2013, about 3 years. This showed that there were more cancers in the control group over that period. The idea clearly was to knock on the head any suggestion that the radiation from Fukushima was the cause of the excess cancers and other illnesses that formed the basis of the court case. And this it apparently did.

The Navy’s move was to compare the matched “unexposed” control group with the Ronald Reagan group. There were 30% more cancers in the control group after adjusting for age. But what I did was compare the nuclear navy-wide control group with the national population, using data on cancer rates by age group from the SEER database[3]. The results show an astonishing 9.2-fold excess of cancer incidence in the sailors on nuclear-powered vessels. There were 121 cancers predicted on the basis of the national rates, and 1,119 reported by the DTRA study. For sailors aboard the Reagan, the excess cancer rate was about 6-fold, with 46 reported and 7.76 expected. Now this result is astonishing. I wrote my study for Cancer Investigation, a good scientific peer-reviewed journal, and it was published Feb. 25, 2020. You can find it on academia.edu[4].

What I discuss in the paper to explain the study’s results is that radiation protection legislation is wildly incorrect when dealing with internal contamination from radionuclides. The legal limits in the US and the West are based on the comparison of cancers in those exposed to acute external gamma ray doses to the Japanese A-Bomb survivors and cannot apply to internal exposures to substances which target DNA (uranium, strontium-90) or which provide huge local doses of ionization to some living cells but nothing at all to others (uranium particles, reactor discharge particles).

This study’s results are a big deal. Nine times the expected rates? What are they going to do? It’s the Navy’s own data that it stupidly released, and it shows that their own sailors on their vaunted nuclear-powered Navy ships are dying from cancer. You can bet the telephone lines are hot, and that we won’t see any coverage of this in the papers or on the tele. But the sailors themselves and the veterans? What will they think when they find this online but not reported?

Studies of nuclear workers have been the new battleground for this chess game since it became apparent in the last few years that the Japanese A-Bomb studies were dishonestly manipulated and ignored internal exposures to fallout and rainout [5]. We have seen a number of attempts to kill the argument about low-dose radiation and health using nuclear worker studies. There was the Lancet publication in 2015 [6]. There was the disgraceful Royal Society publication last year. The late Alexei Yablokov and I wrote to the Lancet [7] asking to point out in the journal that the Lancet’s articles reassuring everyone that the science of radiation risk was secure were written by nuclear industry scientists and were unreliable. The Lancet refused. I wrote to the Royal Society. It also refused to publish anything.

Nuclear workers work outside at a nuclear site where the discharges get dispersed. Nuclear Navy sailors work in a tin can that also houses the reactors. Nuclear worker studies are based on data that is provided by the nuclear industry to show there are no cancers. The Navy’s DTRA study had to show higher overall cancer rates in order to swamp the numbers of cancers among sailors on board the Ronald Reagan. But to do this, and to extend the chess analogy, the Navy brought out its Queen—its cancer statistics—and it was taken.

Thankfully, this story shows that regarding internal radiation exposure, there are two “last frontiers”: the scientific peer-review literature, and the courts. I am also helping represent the widow of a UK nuclear Navy submariner who was a reactor-servicing technician and who died from cancer. Let’s see what the Scottish courts makes of my paper. Read it yourself and have a laugh. If you are a Navy sailor on a nuclear-powered ship, be very frightened. Write to your Senator. Kick up a fuss.

Nukewatch Winter Quarterly 2019-2020

By Cindy Folkers

Hundreds of thousands of people—athletes, officials, media, and spectators—will flood into Japan for the 2020 Olympics. But radiation exposure dangers from the Fukushima nuclear catastrophe have not ended since the meltdowns and explosions spread radioactive contamination over large areas reaching down to Tokyo and beyond. Soon after the start of the meltdowns in 2011, experts began warning of exposure to radioactive micro-particles or “hot particles”—a type of particle that poses a danger unaccounted for by regulatory agencies. In order to understand the special danger posed by these particles at the Olympics and beyond, we must first understand the current state of radiation exposure standards.

Hot Particles Don’t Fit Current Exposure Models

For decades, protection from radiation exposure has been based on understanding how doses are delivered to the human body. Are the doses high or low? Inside or outside the body? If a dose is internal, which organ is it impacting? Is the dose given all at one time, or over a longer time? Additional consideration should be given to who is receiving the exposure: men, women, children, fetuses—although protection based on age, gender and pregnancy falls short.

The difficulty with hot particles, which can travel great distances, is that they don’t deliver doses in the way experts expect. Current exposure assumptions hold that radionuclides settling in the body, i.e. through inhalation or ingestion, deliver a low dose to surrounding cells where they lodge. But these models are not truly reflecting the damage that is occurring. For instance, precise distribution of many radionuclides within the body eludes experts. And radiation doses delivered inside cells, which may seem low to an entire body, are large doses when just single cells or groupings of cells receive them. Hot particles deliver a much larger dose than what is considered “low.” And once they are inhaled or ingested, they deliver it specifically to the (often unpredictable) area of the body where they lodge.

Hot Particles Make Already Unpredictable Damage Worse

Not only can hot particle doses be unpredictable—so can the damage. Called “stochastic,” damage from radiation exposure may occur at all doses [no matter how small]. The higher the dose is, the greater the chance is that damage will happen. However, the severity of the damage is independent of the dose; that is even low doses of radiation can result in severe consequences. Sometimes these consequences take decades to manifest, but for times of life when fast growth is occurring—such as pregnancy or childhood—the damage may show up in a much shorter time frame.

Since all parts of the human body develop from single cells during pregnancy, the severity of a “radiation hit” during this development can be devastating for mother and child, yet governments and the nuclear industry never consider these exposures as having an official radiation impact. Therefore, NO safe dose CAN exist. Stochastic risk, coupled with the additional unpredictable and unaccounted-for risk from radioactive micro-particles, can lead to impacts that are more dangerous and difficult to quantify with currently used methods.

Olympics 2020 and Beyond

Clearly, as Japan prepares to host the 2020 Olympics, the danger posed by exposure to radioactive micro-particles should be considered, in addition to known and better understood radio-cesium contamination. While most of the radioactive particle dust has settled, it can be easily re-suspended by activities such as digging or running, and by rain, wind, snow, and flooding. Health officials in Japan continually fail to act and stop ongoing radioactive exposures. This lack of governmental action puts all residents of Japan at risk, and also any athletes, spectators and visitors that participate in the Olympics.

Currently, the torch relay is scheduled to begin with a special display of the “Flame of Recovery,” as the torch passes through still-contaminated areas of Fukushima Prefecture. Then, the “Grand Start,” the Japanese leg of the Tokyo 2020 Olympic Torch Relay, will occur at “J. Village,” the former disaster response headquarters used during the initial nuclear meltdowns in 2011. It is 12.4 miles from Fukushima-1 wreckage site, and resides close to acres of radioactive topsoil and other material stored in bags. The bags and the cranes moving them are visible on satellite maps dated 2019. After starting in Fukushima, the torch will travel to all remaining prefectures of Japan. Further, there is indication that J. Village (now called National Training Center) is being retrofitted as a practice area for baseball, softball, and soccer. Games hosted in Fukushima Prefecture aren’t the only exposure concern, as radioisotopes have traveled far from the ruined cores of Fukushima’s reactors. Radionuclides from the meltdowns were found in Tokyo’s metropolitan area as late as 2016 and would increase and decrease, researchers observed, based on rainfall and run-off. One “high activity radioactively-hot dust particle” traveled from Fukushima’s ruined core, to a house in Nagoya, Japan—270 miles away.

In our normal lives, each one of us breathes in a modest amount of dust daily. People are also exposed through contaminated food, ingestion of dusts and soil, or through skin contact. Endurance athletes are at a higher risk, since they often eat much more—and take in more breaths per minute—than an average athlete or a person at rest. And, biologically, due to developing cells, children and pregnant women are at a much higher risk from radiation exposure than men. Many Olympic and Paralympic athletes are of childbearing age or adolescents.

Contamination in Japan has not gone away and neither should our awareness. While most of the athletes, coaches and spectators will leave Japan, the contamination remains, impacting generations of people who will have to contend with this danger for much longer than the eight-plus years they have already been through.

Japan’s government policy of dismissing radiation’s dangers, and normalizing exposure to radioactivity, is part of an attempt to resettle people in areas that would allow an external dose of 2 rem per year. Prior to the Fukushima meltdowns, this level was considered high-risk to the general population. This is not an acceptable level of exposure. The radioactive micro-particles found in areas with even lower background levels indicate a significant risk that Japan and governments around the world who support nuclear technologies are covering up. Merely understanding and quantifying these hot particles is not enough. Governments must protect people from exposure everywhere in the world, not just in Japan. The danger of radioactive micro-particles should be added to a long list of reasons why nuclear technology is not safe and should no longer be used.

Nukewatch Quarterly Fall 2019

Japan’s environment minister Yoshiaki Harada said Sept. 10 that the operator of the ruined Fukushima Daiichi nuclear reactors will have to dump huge quantities of radiation-laden waste water directly into the Pacific Ocean—a threat that has enraged local fishermen and nearby countries that share Pacific Ocean-front territory.

Over 1 million cubic meters (or tons) of contaminated water has accumulated at the site since it was struck in March 2011 by the strongest earthquake in Japan’s history and the subsequent tsunami that triggered three reactor meltdowns and forced 164,865 residents to flee their homes.

“The only option will be to drain it into the sea and dilute it,” Harada told a Sept. 9 news briefing in Tokyo, the Guardian reported. “There are no other options,” he said. This claim is false, as there are at least four alternatives to ocean dumping including long-term storage.

Reactor owner Tokyo Electric Power Co. (Tepco) has repeatedly claimed that its filter system removes all the radioactivity from the waste water except tritium. But last year Tepco admitted that its enormous filter system had failed, and that water in the tanks still contains highly radioactive contaminants including radioactive cesium, cobalt, antimony, iodine, strontium, and tritium. The level of contamination in the stored water far exceeds legal limits allowing release into the ocean, and Tepco has promised to refilter the water, a process that will take 5-to-6 years.

Moreover, Greenpeace reports* that the water processing failure was known by Tepco from the beginning of its operation. The company kept the information secret for the five years between 2013 and 2018 because public disclosure would have ruined Tepco’s plans “to solve the enormous water crisis by discharge to the Pacific Ocean.”

Held in 1,000 huge tanks at the site, each with 1,000-1,200 tons of radioactive liquid, Tepco has said that it will run out of on-site space for more tanks by the summer of 2022. The amount of processed water increases between 2,000 and 4,000 tons each week. Dr. Gordon Edwards notes that, “In the next 4-5 years, another 750,000 tons will be added to the inventory.”

According to critics, Japan’s government and Tepco repeatedly suggest the idea of dumping the waste water into the Pacific in order to weaken resistance to the plan and to foster its acceptance among skeptics.

Japan’s Neighbors Complain

The governments of South Korea and Taiwan have formally objected to any ocean dumping of Fukushima waste water, warning that currents will bring the contamination to their own shores.

In addition, South Korea’s Olympic committee has raised concerns about the risk to Olympic athletes who will attend the 2020 summer games in Tokyo. With baseball and softball games set to be played in Fukushima City, South Korea’s committee asked in August whether food served in the Athletes’ Village could be contaminated with radioactive fallout that was widely dispersed by the wrecked reactors. Japan’s Olympic Committee replied by down playing the concerns.

South Korea should restrict imports of processed foods from Japan’s Fukushima region as radiation has been found in shipments, an opposition lawmaker said Aug. 19, Korea Times reports. Citing data from the Ministry of Food and Drug Safety, South Korean Rep. Kim Kwang-soo of the Party for Democracy and Peace has reported that radiation was discovered in almost 17 tons of processed foods imported from the eight prefectures, or 35 shipments, over the past five years. South Korea banned seafood imports from states or prefectures near Fukushima in 2013 over reports of radioactive contamination. But no import restrictions have been put on processed foods from the areas. —JL
