*Fukushima mothers at UN tell their story — Beyond Nuclear International

” When Kazumi Kusano stood in the CRIIRAD radiological laboratory in Valence, France listening to lab director, Bruno Chareyron, describe just how radioactive the soil sample taken from a school playground back home in Japan really was, she could not fight back the tears.

“This qualifies as radioactive waste,” Chareyron told them. “The children are playing in a school playground that is very contaminated. The lowest reading is 300,000 bequerels per square meter. That is an extremely high level.” (CRIIRAD is the Commission for Independent Research and Information about Radiation, an independent research laboratory and NGO).

Kazumi, a Japanese mother and Fukushima evacuee who prefers not to use her real name, was in France with two other mothers, Mami Kurumada and Akiko Morimatsu — all of whom also brought their children — as part of an educational speaking tour. Morimatsu was also invited to testify before the UN Commission on Human Rights in Geneva, to launch an appeal for the rights of nuclear refugees.

In Japan, seven years since the March 2011 Fukushima nuclear disaster began to unfold, the government is requiring some refugees to return to the region. Says Chareyron, whose lab has worked extensively in the Fukushima zone, “the Japanese government is doing everything to force citizens to return to lands where the radiation doses that citizens and children should be subjected to are largely over the typically acceptable norms.”

“People in Japan still don’t believe that the effects they are feeling are due to radiation,” said Kusano during one of the tour stops in France. Indeed, when they took samples in their neighborhoods to be analyzed for radioactive contamination, they were mocked not only by their neighbors but by government officials.

“We don’t take this seriously in Japan,” said Kurumada, who expressed relief to be among those who understand the true dangers, like Chareyron and the French anti-nuclear activists with whom they met. “In our country, it’s taboo to talk about radiation and contamination.”

Both Kusano and Kurumada are among those who have brought lawsuits against Tepco and the Japanese government, seeking compensation for Fukushima evacuees. Several of these have already ruled in favor of the evacuees and have assigned responsibility for the accident to Tepco and the government while providing financial awards to the plaintiffs. (Kusano’s son’s testimony helped win one of those cases — see our earlier coverage.)

The Japanese government pressured evacuees to return to areas contaminated by the Fukushima disaster by withdrawing their government financial assistance. However, many in areas that were not obligatory evacuation zones also left the region, given the high levels of radioactive contamination.

In addition to the visit to CRIIRAD, the mothers also spoke at public meetings in Lyon, Grenoble and Valence where CRIIRAD is located. The short news video below, in French, captures their visit to the lab.

At the UN in Geneva, Morimatsu’s testimony was postponed several days by a workforce strike. But eventually, Morimatsu (pictured with her son above the headline) was able to deliver her speech. She said:

“My name is Akiko Morimatsu. I am here with other evacuees and mothers, together with Greenpeace. I evacuated from the Fukushima disaster with my two children in May 2011. Shortly after the nuclear accident, radiation contamination spread. We were repeatedly and unnecessarily exposed to unannounced radiation.

“The air, water and soil became severely contaminated. I had no choice but to drink the contaminated water, to breast-feed my baby. To enjoy health, free from radiation exposure, is a fundamental principle. The Japanese Constitution states, ‘We recognize that all peoples of the world have the right to live in peace, free from fear and want.’

“However, the Japanese government has implemented almost no policies to protect its citizens. Furthermore, the government is focusing on a policy to force people to return to highly contaminated areas.

“I call on the Japanese government to immediately, fully adopt and implement the recommendations of the UN Human Rights Council. I thank UN member states for defending the rights of residents in Japan. Please help us protect people in Fukushima, and in East Japan, especially vulnerable children, from further radiation exposure.”

Earlier that month, the Japanese government had responded to its Universal Periodic Review, by stating that it “supports” 145 recommendations and “notes” 72. One of those recommendations from the UN Human Rights Council, and which Japan “accepted”, was the paragraph that states: “Respect the rights of persons living in the area of Fukushima, in particular of pregnant women and children, to the highest level of physical and mental health, notably by restoring the allowable dose of radiation to the 1 mSv/year limit, and by a continuing support to the evacuees and residents (Germany);”

According to Hajime Matsukubo of Citizens Nuclear Information Center in Tokyo, while the Upper House of the Japanese Diet has indicated its willingness to decrease annual radiation exposures from 20 mSv, the Japanese government has only said it would “follow up” on the specific UN recommendation and report back later. There is no timeframe for such a change, hardly surprising since it would presumably mean once more evacuating people the government has already pressured to return to contaminated areas. The practical implications of this happening leave it very much in doubt.

However, Matsukubo believes that even the commitment to follow up “is a strong tool for us to push the government forward.” Aileen Mioko Smith of Kyoto-based Green Action agrees. “Now we have terrific leverage,” she said. Her group, along with Greenpeace Japan will be looking to “keep the Japanese government’s feet to the fire on this.”

Fukushima residents fight state plan to build roads with radiation-tainted soil — The Japan Times

” The Environment Ministry plans to use radiation-tainted soil to build roads in Fukushima Prefecture, starting with trials in the city of Nihonmatsu next month.

But in the face of fierce protests from safety-minded residents, the ministry is struggling to advance the plan.

“Don’t scatter contaminated soil on roads,” one resident yelled during a Thursday briefing by Environment Ministry officials in Nihonmatsu.

The officials repeatedly tried to soothe them with safety assurances, but to no avail.

“Ensuring safety is different from having the public feeling at ease,” said Bunsaku Takamiya, a 62-year-old farmer who lives near a road targeted for the plan. He claims the project will produce groundless rumors that nearby farm produce is unsafe.

Seven years after the March 2011 core meltdowns at the Fukushima No. 1 nuclear plant, Takamiya has finally been able to ship his produce in Fukushima without worry. Then the ministry’s soil plan surfaced.

A woman in the neighborhood agrees.

“The nature and air here are assets for the residents. I don’t want them to take it away from us,” she said.

Under the plan, tainted soil will be buried under a 200-meter stretch of road in the city. The soil, packed in black plastic bags, has been sitting in temporary storage.

The plan is to take about 500 cu. meters of the soil, bury it under the road at a depth of 50 cm or more, cover it with clean soil to block radiation, and pave over it with asphalt. The ministry intends to take measurements for the project in May.

Fukushima is estimated to have collected about 22 million cu. meters of tainted soil at most. The ministry plans to put it in temporary storage before transporting it to a final disposal site outside the prefecture.

The idea is to reduce the amount. The ministry thus intends to use soil with cesium emitting a maximum of 8,000 becquerels per kg in public works projects nationwide.

The average radiation level for soil used for road construction is estimated at about 1,000 becquerels per kg, the ministry says.

The ministry has already conducted experiments to raise ground levels in Minamisoma with the tainted soil, saying “a certain level” of safety was confirmed.

Similar plans are on the horizon regarding landfill to be used for gardening in the village of Iitate. But it is first time it will be used in a place where evacuations weren’t issued after the March 2011 meltdowns.

Given the protests, an official linked to the ministry said, “It’s difficult to proceed as is.” ”

Fukushima’a other big problem: A Million tons of radioactive water — Wired

” The tsunami-driven seawater that engulfed Japan’s Fukushima Daiichi nuclear plant has long since receded. But plant officials are still struggling to cope with another dangerous flood: the enormous amounts of radioactive water the crippled facility generates each day. More than 1 million tons of radiation-laced water is already being kept on-site in an ever-expanding forest of hundreds of hulking steel tanks—and so far, there’s no plan to deal with them.

The earthquake and tsunami that hammered Fukushima on March 11, 2011 triggered meltdowns in three of its six reactors. That left messes of intensely radioactive fuel somewhere loose in the reactor buildings—though no one knows exactly where. What is known, however, is that every day, as much as much as 150 tons of groundwater percolates into the reactors through cracks in their foundations, becoming contaminated with radioactive isotopes in the process.

To keep that water from leaking into the ground or the Pacific, Tepco, the giant utility that owns the plant, pumps it out and runs it through a massive filtering system housed in a building the size of a small aircraft hangar. Inside are arrays of seven-foot tall stainless steel tubes, filled with sand grain-like particles that perform a process called ion exchange. The particles grab on to ions of cesium, strontium, and other dangerous isotopes in the water, making room for them by spitting out sodium. The highly toxic sludge created as a byproduct is stored elsewhere on the site in thousands of sealed canisters.

This technology has improved since the catastrophe. The first filtering systems, installed just weeks after the disaster by California-based Kurion Inc. (which has since been bought by Veolia, a French resource management company), only caught cesium, a strong gamma radiation emitter that makes it the most dangerous of the isotopes in the water. The tubes in those arrays were filled with highly modified grains of naturally occurring volcanic minerals called zeolites. By 2013, the company developed entirely artificial particles—a form of titano silicate—that also grab strontium.

The filters, however, don’t catch tritium, a radioactive isotope of hydrogen. That’s a much trickier task. Cesium and strontium atoms go into solution with the water, like sugar in tea; but tritium can bond with oxygen just like regular hydrogen, rendering the water molecules themselves radioactive. “It’s one thing to separate cesium from water, but how do you separate water from water?” asks John Raymont, Kurion’s founder and now president of Veolia’s nuclear solutions group. The company claims to have developed a system that can do the job, but Tepco has so far balked at the multi-billion dollar cost.

So for now, the tritiated water is pumped into a steadily growing collection of tanks. There are already hundreds of them, and Tepco has to start building a new one every four days.

Tepco has at least reduced the water’s inflow. As much as 400 tons per day was gushing in just a couple of years ago. In an effort to keep the groundwater from getting in, Tepco has built a network of pumps, and in 2016 installed an underground “ice wall”—a $300 million subterranean fence of 30-yard-long rods through which tons of sub-zero brine is pumped, freezing the surrounding earth. All of which helps, but hasn’t solved the problem.

Tritium is far less dangerous than cesium—it emits a weaker, lower-energy form of radiation. Still, all that tritiated water can’t just be stored indefinitely. “Some of those tanks and pipes will eventually fail. It’s inevitable,” says Dale Klein, a former head of the US Nuclear Regulatory Commission who has been consulting with Tepco since the early days following the disaster. (In fact, hundreds of tons of water leaked out of the tanks in 2013 and 2014, sparking an international outcry. Tepco has since improved their design.)

Klein, among others, believes that the concentrations of tritium are low enough that the water can safely be released into the sea. “They should dilute and dispose of it,” he says. “It would be better to have a controlled release than an accidental one.”

But the notion of dumping tons of radioactive water into the ocean is understandably a tough sell. Whatever faith the Japanese public had left in Tepco took a further beating in the first couple of years after the meltdowns, when several investigations forced the company to acknowledge they had underreported the amount of radiation released during and after the disaster. Japan’s fishing industry raises a ruckus whenever the idea of dumping the tritiated water is broached; they already have to contend with import restrictions imposed by neighboring countries worried about eating contaminated fish. Japan’s neighbors including China, Korea, and Taiwan have also objected.

For now, all Tepco can do is keep building tanks, and hope that someone comes up with a solution before they run out of room—or the next earthquake hits. “

Move over Chernobyl, Fukushima is now officially the worst nuclear power disaster in history — CounterPunch

” The radiation dispersed into the environment by the three reactor meltdowns at Fukushima-Daiichi in Japan has exceeded that of the April 26, 1986 Chernobyl catastrophe, so we may stop calling it the “second worst” nuclear power disaster in history. Total atmospheric releases from Fukushima are estimated to be between 5.6 and 8.1 times that of Chernobyl, according to the 2013 World Nuclear Industry Status Report. Professor Komei Hosokawa, who wrote the report’s Fukushima section, told London’s Channel 4 News then, “Almost every day new things happen, and there is no sign that they will control the situation in the next few months or years.”

Tokyo Electric Power Co. has estimated that about 900 peta-becquerels have spewed from Fukushima, and the updated 2016 TORCH Report estimates that Chernobyl dispersed 110 peta-becquerels. (A Becquerel is one atomic disintegration per second. The “peta-becquerel” is a quadrillion, or a thousand trillion Becquerels.)

Chernobyl’s reactor No. 4 in Ukraine suffered several explosions, blew apart and burned for 40 days, sending clouds of radioactive materials high into the atmosphere, and spreading fallout across the whole of the Northern Hemisphere — depositing cesium-137 in Minnesota’s milk.

The likelihood of similar or worse reactor disasters was estimated by James Asselstine of the Nuclear Regulatory Commission (NRC), who testified to Congress in 1986: “We can expect to see a core meltdown accident within the next 20 years, and it … could result in off-site releases of radiation … as large as or larger than the releases … at Chernobyl. Fukushima-Daiichi came 25 years later.

Contamination of soil, vegetation and water is so widespread in Japan that evacuating all the at-risk populations could collapse the economy, much as Chernobyl did to the former Soviet Union. For this reason, the Japanese government standard for decontaminating soil there is far less stringent than the standard used in Ukraine after Chernobyl.

Fukushima’s Cesium-137 Release Tops Chernobyl’s

The Korea Atomic Energy Research (KAER) Institute outside of Seoul reported in July 2014 that Fukushima-Daiichi’s three reactor meltdowns may have emitted two to four times as much cesium-137 as the reactor catastrophe at Chernobyl.

To determine its estimate of the cesium-137 that was released into the environment from Fukushima, the Cesium-137 release fraction (4% to the atmosphere, 16% to the ocean) was multiplied by the cesium-137 inventory in the uranium fuel inside the three melted reactors (760 to 820 quadrillion Becquerel, or Bq), with these results:

Ocean release of cesium-137 from Fukushima (the worst ever recorded): 121.6 to 131.2 quadrillion Becquerel (16% x 760 to 820 quadrillion Bq). Atmospheric release of Cesium-137 from Fukushima: 30.4 to 32.8 quadrillion Becquerel (4% x 760 to 820 quadrillion Bq).

Total release of Cesium-137 to the environment from Fukushima: 152 to 164 quadrillion Becquerel. Total release of Cesium-137 into the environment from Chernobyl: between 70 and 110 quadrillion Bq.

The Fukushima-Daiichi reactors’ estimated inventory of 760 to 820 quadrillion Bq (petabecquerels) of Cesium-137 used by the KAER Institute is significantly lower than the US Department of Energy’s estimate of 1,300 quadrillion Bq. It is possible the Korean institute’s estimates of radioactive releases are low.

In Chernobyl, 30 years after its explosions and fire, what the Wall St. Journal last year called “the $2.45 billion shelter implementation plan” was finally completed in November 2016. A huge metal cover was moved into place over the wreckage of the reactor and its crumbling, hastily erected cement tomb. The giant new cover is 350 feet high, and engineers say it should last 100 years — far short of the 250,000-year radiation hazard underneath.

The first cover was going to work for a century too, but by 1996 was riddled with cracks and in danger of collapsing. Designers went to work then engineering a cover-for-the-cover, and after 20 years of work, the smoking radioactive waste monstrosity of Chernobyl has a new “tin chapeau.” But with extreme weather, tornadoes, earth tremors, corrosion and radiation-induced embrittlement it could need replacing about 2,500 times. ”

Stark health findings for Fukushima monkeys — Beyond Nuclear International

” Seven years after the Fukushima, Japan nuclear disaster began, forcing evacuations of at least 160,000 people, research has uncovered significant health impacts affecting monkeys living in the area and exposed to the radiological contamination of their habitat.

Shin-ichi Hayama, a wild animal veterinarian, has been studying the Japanese macaque (Macaca fuscata), or snow monkey, since before the Fukushima nuclear disaster. Now, his research has shown that monkeys in Fukushima have significantly low white and red blood cell counts as well as a reduced growth rate for body weight and smaller head sizes.

Hayama, who began his macaque research in 2008, had access to monkeys culled by Fukushima City as a crop protection measure. He continued his work after the Fukushima nuclear explosions. As a result, he is uniquely positioned to discover how low, chronic radiation exposure can affect generations of monkeys.

The macaque is an old world monkey native to Japan, living in the coldest climates of all of the non-human primates. Like humans, macaques enjoy a good soak in the mountain hot springs in the region. It is even said that they have developed a “hot tub culture” and enjoy time at the pools to get warm during winter.

However, snow monkeys and humans share more than a love of hot springs. Human DNA differs from rhesus monkeys, a relative of the snow monkey, by just 7%. While that 7% can mean the difference between building vast cities to living unsheltered and outdoors, for basic processes like reproduction, these differences begin to fade. Consequently, what is happening to the macaques in Fukushima should send a warning about the implications for human health as well, and especially for evacuees now returning to a region that has been far from “cleaned up” to any satisfactory level.

Hayama’s research group has published two studies, each comparing data before and after the nuclear catastrophe began, and also between exposed and unexposed monkey populations. In a 2014 study, researchers compared monkeys from two regions of Japan, one group of monkeys from the Shimokita region, 400 Km north of Fukushima, and a second group of monkeys from contaminated land in Fukushima.

The monkeys in Fukushima had significantly low white and red blood cell counts. Other blood components were also reduced. The more a radioactive isotope called cesium was present in their muscles, the lower the white blood cell count, suggesting that the exposure to radioactive material contributed to the damaging blood changes. These blood levels have not recovered, even through 2017, meaning that this has become a chronic health issue.

Changes in blood are also found in people inhabiting contaminated areas around Chernobyl. Having a diminished number of white blood cells, which fight disease, can lead to a compromised immune system in monkeys as well as people, making both species unable to fight off all manner of disease.

Hayama followed up his 2014 study with another in 2017 examining the differences in monkey fetus growth before and after the disaster. The researchers measured fetuses collected between 2008 and 2016 from Fukushima City, approximately 70 km from the ruined reactors. Comparing the relative growth of 31 fetuses conceived prior to the disaster and 31 fetuses conceived after the disaster revealed that body weight growth rate and head size were significantly lower in fetuses conceived after the disaster. Yet, there was no significant difference in maternal nutrition, meaning that radiation could be responsible.

Smaller head size indicates that the fetal brain was developmentally retarded although researchers could not identify which part was affected. The mothers’ muscles still contained radioactive cesium as in the 2014 study, although the levels had decreased. These mothers had conceived after the initial disaster began, meaning that their fetuses’ health reflects a continuing exposure from environmental contamination. This study mirrors human studies around Chernobyl that show similar impacts as well as research from atomic bomb survivors. Studies of birds in Chernobyl contaminated areas show that they have smaller brains.

Although Hayama has approached radiation experts to aid with his research, he claims they have rejected it, saying they don’t have resources or time, preferring to focus on humans. But humans can remove themselves from contaminated areas, and many have chosen to stay away despite government policies encouraging return. Tragically, monkeys don’t know to leave, and relocating them is not under discussion, making study of radiation’s impact on their health vital to inform radiation research on humans, the environment, and any resettlement plans the government of Japan may have.

Hayama presented his work most recently as part of the University of Chicago’s commemoration of the 75th Anniversary of the first man-made controlled nuclear chain reaction. His work follows a long, important, and growing line of research demonstrating that radiation can not only damage in the obvious ways we have been told, but in subtle, yet destructive ways that were unexpected before. The implications for humans, other animals, and the environment, are stark. ”

Experts: Fukushima must do more to reduce radioactive water — U.S. News

Here is a good article written by Mari Yamaguchi that explains the state of contaminated water at the Fukushima Daiichi plant. Experts say that the ice wall that was built to keep groundwater from coming into the power plant and becoming contaminated with radioactivity is only half effective. A conventional drainage system also collects water from wells dug around the plant and pumps it out before it becomes contaminated. This water is stored in about 1,000 storage tanks near the facility. Read more about the construction, operation and maintenance costs that are coming out of the taxpayer’s pocket.
