Three Ways Radiation Has Changed The Monkeys Of Fukushima

Jeff McMahon

This year the evacuated residents of Japan’s Fukushima Prefecture began returning home, and as they resume their lives, the monkeys who have lived there all along have some cautions for them—in the form of medical records.

The Japanese macaques show effects associated with radiation exposure—especially youngsters born since the March 2011 meltdowns at the Fukushima-Daiichi Nuclear Power Plant, according to a wildlife veterinarian who has studied the population since 2008.

Dr. Shin-ichi Hayama detailed his findings Saturday in Chicago as part of the University of Chicago’s commemoration of the 75th Anniversary of the first man-made controlled nuclear reaction, which took place under the university’s football stadium in 1942 and birthed the technologies of nuclear power and nuclear weapons.

Hayama appeared alongside documentary filmmaker Masanori Iwasaki, who has featured Hayama’s work in a series of annual documentaries exploring the impact of fallout from the reactor meltdowns on wildlife. The fallout led the Japanese government to evacuate residents from a highly contaminated area surrounding the plant and extending to the northwest. The plume crossed the Pacific Ocean and left much diluted quantities of fallout across the United States, an event closely monitored on this page.

Since 2008, Hayama has studied the bodies of monkeys killed in Fukushima City’s effort to control the monkey population and protect agricultural crops (about 20,000 monkeys are “culled” annually in Japan). Because he was already studying the monkeys, he was ideally positioned to notice changes affected by radiation exposure.

“I’m not a radiation specialist,” Hayama said Saturday in Chicago, “but because I’ve been gathering data since 2008—remember, the disaster took place in 2011—it seems obvious to me that this is very important research. I’ve asked radiation specialists to take on this research, but they have never been willing to take this on because they say we don’t have any resources or time to spare because humans are much more important.

“So I had to conclude that there was no choice but for me to take this on, even though I’m not a specialist in radiation,” Hayama said, his remarks translated by University of Chicago Professor Norma Field. “If we don’t keep records, there will be no evidence and it will be as if nothing happened. That’s why I’m hoping to continue this research and create a record.”

Fukushima City is 50 miles northeast of the Fukushima-Daiichi Power Plant, so the radiation levels have been lower there than in the restricted areas, now reopening, that are closer to the plant. Hayama was unable to test monkeys in the most-contaminated areas, but even 50 miles from the plant, he has documented effects in monkeys that are associated with radiation. He compared his findings to monkeys in the same area before 2011 and to a control population of monkeys in Shimokita Peninsula, 500 miles to the north.

Hayama’s findings have been published in the peer-reviewed journal Scientific Reports, published by Nature. Among his findings:

Smaller Bodies — Japanese monkeys born in the path of fallout from the Fukushima meltdown weigh less for their height than monkeys born in the same area before the March, 2011 disaster, Hayama said.

“We can see that the monkeys born from mothers who were exposed are showing low body weight in relation to their height, so they are smaller,” he said.

Smaller Heads And Brains — The exposed monkeys have smaller bodies overall, and their heads and brains are smaller still.

“We know from the example of Hiroshima and Nagasaki that embryos and fetuses exposed in utero resulted in low birth weight and also in microcephaly, where the brain failed to develop adequately and head size was small, so we are trying to confirm whether this also is happening with the monkeys in Fukushima,” Hayama said.

And it appears that it is.

Anemia — The monkeys show a reduction in all blood components: red blood cells, white blood cells, hemoglobin, and the cells in bone marrow that produce blood components.

“There’s clearly a depression of blood components in the Fukushima monkeys,” said Hayama. “We can see that in these monkeys, that there is a correlation between white blood cell counts and the radio-cesium concentrations in their muscles. This actually is comparable to what’s been reported with children of Chernobyl.”

“We have taken these tests from 2012 through 2017, and the levels have not recovered. So we have to say this is not an acute phenomenon. It has become chronic, and we would have to consider radiation exposure as a possible cause,” Hayama said.

Hayama has appeared in several documentaries by Masanori Isawaki, who was 70 years old in 2011 and ready to retire from a thirty-year career making wildlife documentaries—he is best known for his portrait of “Mozu: The Snow Monkey”—when the Fukushima reactors melted down.

“Having turned 70 I thought, I’ve done enough, I can sit back. And then the nuclear disaster struck,” he said, his remarks also translated by Field. “I watched TV shows and read the newspaper for a year and kept asking myself, is there something left in me that I can do? A year later in 2012, with a cameraman and a sound engineer, the three of us just decided: In any case let’s just go to Fukushima, see what’s there.”

Since then he has made five films, one each year, documenting radiation impacts on wildlife, grouping them under the title “Fukushima: A Record of Living Things”. Two episodes were screened Saturday in Chicago, their first screenings in the United States.

At first Iwasaki documented white spots and deformed tails on the reduced number of barn swallows who survived after the disaster.

“It’s something we haven’t seen anywhere else but Chernobyl and Fukushima,” says the narrator of Iwasaki’s 2013 film, “so it’s clearly related to radiation. It probably doesn’t hurt the bird to have some white feathers, but it’s a marker of exposure to radiation.

“The barn swallows in Fukushima are responding in the same way as what we’ve seen in Chernobyl. The young birds are not surviving. They are not fledging very well.”

The white spots also turned up on black cows. Some types of marine snails vanished, then gradually returned. Fir trees stemmed differently, and the flower stalks of some dandelions grew thick and deformed. Dandelion stalks are a favorite food of Japanese monkeys, but the monkeys showed no obvious deformities, so Isawaki turned to Hayama to find out how radiation was affecting them.

Iwasaki’s 2017 film, just completed, is his first to investigate effects in the monkeys’ primate cousins, the humans: an unusually large number of children with thyroid cancer. ”

Radioactive material from the Fukushima Dai-ichi nuclear power plant disaster is accumulating in the sands and brackish groundwater beneath beaches up to 60 miles away from the nuclear power plant itself, according to a new study published in the Proceedings of the National Academy of Sciences on October 2. The study is the first to identify accumulations of radioactive cesium in this previously unsuspected place: here.

Chernobyl disaster radioactivity in Swedish wild boars


This video from the USA says about itself:

14 March 2017

In the aftermath of the Fukushima disaster, boars populations have skyrocketed. Cenk Uygur, John Iadarola, and Jordan Chariton, the hosts of The Young Turks, give you updates on the Fukushima disaster.

“Six years after an earthquake and tsunami led to three nuclear reactors melting down, Japan is still generating and struggling with staggering amounts of radioactive waste.

In November, the Japanese government said cleanup and compensation costs for the March 2011 Fukushima Dai-ichi disaster would be an unprecedented 20 trillion yen ($180 billion) — double the previous estimate. Nuclear safety may not come cheap for an industry that is increasingly noncompetitive nationally and globally, but lack of safety is very costly indeed.

Soaring costs and accumulating waste aren’t Fukushima’s only problems. While the government wants to start lifting evacuation orders on some towns within the 12-mile exclusion zone, potential returnees have to deal with hundreds of radioactive wild boars roaming the streets. Reuters reports that some boars have “levels of radioactive material 130 times above Japan’s safety standards.”

“After people left, their ecosystem changed,” explained one local hunter hired to deal with the boars. “They began coming down from the mountains and now they aren’t going back. They found plenty of food, and no one will come after them. This is their new home now.” More than 13,000 boars have been hunted so far.”

30 years after the Chernobyl disaster, radioactive wild boar suddenly turn up in Sweden

Swine eat truffles containing radiation from the Chernobyl disaster in 1986

More than thirty years after the nuclear disaster in Chernobyl, radioactive wild boar suddenly show up in Sweden. This is because the Swedish boar now comes to places in nature where they did not dare until recently.

By Eric Van Den Outenaar October 9, 2017, 19:06

Nature areas in the middle and north of Sweden received a big radioactive cloud during the spring of 1986 from Ukraine. As a result, no berries and mushrooms were allowed to be picked for a long time. Most plants and animals have recovered.

For the wild boars, however, things go from bad to worse. …

The highest measured radioactivity in a wild boar so far is 16 thousand becquerel per 1,000 grams of pork, reported the Swedish public broadcaster SVT. At 10 thousand becquerel per 1,000 grams, the Swedish Food and Food Authority considers the eating of wild pork irresponsible.

BBC News: Toxic radioactive isotope found in Fukushima groundwater

19 June 2013

High levels of a toxic radioactive isotope have been found in groundwater at Japan’s Fukushima nuclear plant, its operator says.

Radioactive material from Fukushima disaster turns up in a surprising place

Some of highest levels of cesium-137 contamination are in groundwater under nearby sandy beaches

Six years after the Fukushima nuclear reactor disaster in Japan, radioactive material is leaching into the Pacific Ocean from an unexpected place. Some of the highest levels of radioactive cesium-137, a major by-product of nuclear power generation, are now found in the somewhat salty groundwater beneath sand beaches tens of kilometers away, a new study shows.

Scientists tested for radioactivity at eight different beaches within 100 kilometers of the plant, which experienced three reactor meltdowns when an earthquake and tsunami on March 11, 2011, knocked out its power. Oceans, rivers and fresh groundwater sources are typically monitored for radioactivity following a nuclear accident, but several years following the disaster, those weren’t the most contaminated water sources. Instead, brackish groundwater underneath the beaches has accumulated the second highest levels of the radioactive element (surpassed only by the groundwater directly beneath the reactor), researchers report October 2 in the Proceedings of the National Academy of Sciences.

In the wake of the 2011 accident, seawater tainted with high levels of cesium-137 probably traveled along the coast and lapped against these beaches, proposes study coauthor Virginie Sanial, who did the work while at Woods Hole Oceanographic Institution in Massachusetts. Some cesium stuck to the sand and, over time, percolated down to the brackish groundwater beneath. Now, the radioactive material is steadily making its way back into the ocean. The groundwater is releasing the cesium into the coastal ocean at a rate that’s on par with the leakage of cesium into the ocean from the reactor site itself, Sanial’s team estimates.

Since this water isn’t a source of drinking water and is underground, the contamination isn’t an immediate public health threat, says Sanial, now a geochemist at the University of Southern Mississippi in Hattiesburg. But with about half of the world’s nuclear power plants located on coastlines, such areas are potentially important contamination reservoirs and release sites to monitor after future accidents.

Radioactive Salmon Discovered in Canada Linked to Fukushima Nuclear Contamination

22 December 2016

A team of research scientists from the University of Victoria in Canada discovered radioactive salmon due to Fukushima nuclear contamination.

Researchers at the Fukushima InFORM project in Canada, led by University of Victoria chemical oceanographer Jay Cullen, said they sampled a sockeye salmon from Okanagan Lake in British Columbia that tested positive for cesium 134.

This finding comes after seaborne cesium 123, which is thought to be an indicator of nuclear contamination from Fukushima, was detected on the West Coast of the United States this month.

It’s the first time Canadian experts confirmed the news that radioactive plume has made its way across the Pacific to America’s West Coast from the demolished Fukushima Daiichi nuclear power plant in eastern Japan.

Cullen with his research team as well as 600 volunteers started their research on the Fukushima nuclear contamination in 2014 and have collected fish and seawater samples.

Cesium 134 is called the “footprint of Fukushima” because of its fast rate of decay. With a half life of only 2.06 years, there are few other places the dangerous and carcinogenic isotope could have originated.

“In 2015, we collected an individual fish that we could detect artificial radioactivity in the fish itself. This contrasts with almost all the other fish we’ve collected on the order of about 400 fish over those three years where we were unable to actually detect any artificial radionuclides in the individuals. In this particular one, we can detect cesium-137 which is artificial, a man made radio nuclide, and so we decided to have a more careful look to see if some of that contamination was related to Fukushima. The way that we do that is to look for cesium-134 and that isotope has a relatively short half life of two years, and if we see cesium-134 in a fish today, we know that it has been affected by Fukushima. When we count for longer, we can see smaller and smaller amounts of radioactivity,” said Jay Cullen, professor of the School of Earth and Ocean Sciences with the University of Victoria.

It is important to note that airborne radioactive fallout from the initial explosion and meltdowns at Fukushima in 2011 reached the USA and Canada within days, and circled the globe falling out wherever the currents and precipitation carried it – mostly to places unknown to this day.

Fukushima’s tritiated water to be dumped into sea, Tepco chief says

July 14, 2017

Despite the objections of local fishermen, the tritium-tainted water stored at the Fukushima No. 1 nuclear plant will be dumped into the sea, a top official at Tokyo Electric says.

“The decision has already been made,” Takashi Kawamura, chairman of Tokyo Electric Power Company Holdings Inc., said in a recent interview with the media. …

As of July 6, about 777,000 tons were stored in about 580 tanks at the Fukushima plant, which is quickly running out of space.

Tepco’s decision has local fishermen worried that their livelihood is at risk because the radioactive material will further mar public perceptions about the safety of their catches.

Kawamura’s remarks are the first by the utility’s management on the sensitive matter. Since the March 2011 meltdowns were brought under control, the Fukushima No. 1 plant has been generating tons of toxic water that has been filling up hundreds of tanks at the tsunami-hit plant.

Kawamura’s comments came at a time when a government panel is still debating how to deal with the tritium issue, including whether to dump it all into sea.

Saying its next move is contingent on the panel’s decision, Kawamura hinted in the interview that Tepco will wait for the government’s decision before actually releasing the tainted water into the sea.

“We cannot keep going if we do not have the support of the state” as well as Fukushima Prefecture and other stakeholders, he said. …

But fishermen who make their livelihoods from sea life near the plant are opposed to the releases because of how the potential ramifications will affect their lives. …

Tachiya, of the cooperative that includes fishermen from the towns of Futaba and Okuma, which host the plant, took a swipe at Tepco’s decision, saying there has been “no explanation whatsoever from Tepco to local residents.”

On March 11, 2011, a tsunami inundated the six-reactor plant, situated 10 meters above sea level, and flooded the power supply, causing a station blackout. The cooling systems of reactors 1, 2 and 3 were thus crippled, leading to core meltdowns that became the world’s worst nuclear disaster since Chernobyl in 1986.

Water is being constantly injected into the leaking reactors to keep the molten fuel cool, creating tons of extremely toxic water 24/7. Although it is filtered through a complex processing system, extracting the tritium is virtually impossible.

Fishermen express fury as Fukushima plant set to release radioactive material into ocean — The Telegraph: here.

” It’ll be a tough journey – previous robots sent in to the ruined nuclear reactor didn’t make it back. … ” View BBC News’ photo essay on Toshiba’s newest swimming robot, a “little sunfish” that is hoped to withstand off-the-charts radiation levels in Fukushima Daiichi’s wrecked containment vessel: here.

Japan’s Homeless Recruited to Clean Up Fukushima Radioactive Hotspots

30 December 2013

It is five o’clock in the morning and close to freezing point in Sendai, 360 kilometres (200 miles) north of Tokyo.

For those living rough, this station is one of the warmest places to sleep, however, their refuge is also a recruiting ground for labour brokers. The men in Sendai Station are potential labourers who can be dispatched to contractors in Japan’s nuclear disaster zone for a bounty of $100 a head.

Shizuya Nishiyama, who is 57, has been homeless for a year and sleeps on a cardboard box, next to a shop window in Sendai station.

Twice Nishiyama says he has been recruited to scrub down radioactive hotpots in Fukushima, 80 kilometres (50 miles) to the south.

“We’re an easy target for recruiters. We turn up here with all our bags, wheeling them around and around the station and we’re easy to spot,” Nishiyama said as the first passengers of the day hurried to their trains.

Nishiyama’s first employer in Sendai offered him $90 a day for his first job clearing tsunami debris unrelated to the Fukushima site. However, he was made to pay as much as $50 a day for food and lodging. He also was not paid on the days he was unable to work. On those days, though, he would still be charged for room and board. He decided he was better off living on the street than going into debt.

“They say to us: ‘Are you looking for work? Are you hungry?’ And if we haven’t eaten anything, they then offer to find us a job,” Nishiyama added.

Almost three years ago, a massive earthquake and tsunami levelled villages across Japan’s northeast coast and set off multiple meltdowns at the Fukushima nuclear plant. Today, the most ambitious radiation clean-up ever attempted is running behind schedule. The effort is being dogged by both a lack of oversight and a shortage of workers, according to a Reuters analysis of contracts and interviews with dozens of those involved.

In Sendai, the largest city on Japan’s tsunami-devastated northeast coast, homeless people like Nishiyama have flocked here in the hope of finding reconstruction work in the disaster zone.

Activists have said that those jobs are increasingly hard to find. Now more than 300 people live rough in Sendai, twice as many as before the March 11 earthquake and tsunami.

For companies operating near the Fukushima Daiichi nuclear plant, that has presented an opportunity.

“There’s this problem where workers are reaching their radiation limits in Fukushima, and are not allowed to continue working. There’s actually an overall shortage of people available to do those dangerous jobs. So it’s to make up that shortfall that homeless people are now being made to risk their lives,” said Yasuhiro Aoki, a Baptist pastor and head of a support group for Sendai’s homeless.

The shortage of those willing and available to take on dirty and dangerous jobs in Fukushima has not pushed wages higher, workers, lawyers and volunteers said.

Responsibility for monitoring the hiring, safety records and suitability of hundreds of small firms involved in Fukushima’s decontamination rests with the top contractors, including Kajima Corp, Taisei Corp and Shimizu Corp, officials said.

As a practical matter, however, many of the construction companies involved in the clean-up say it is impossible to monitor what is happening on the ground because of the multiple layers of contracts for each job that keep the top contractors removed from those doing the work.

Wage data provided by police in one investigated case showed that after deductions for food and lodging, workers were left with an hourly rate of about $6, just below the minimum wage equal to about $6.50 per hour in Fukushima. Some of the homeless men ended up in debt after fees for food and housing were deducted, police said.

Aoki explained the homeless people’s situation further.

“Without any information about potential dangers, many homeless people are just put into dormitories – and the fees for lodging and food automatically docked from their wages. Then, at the end of the month, they’re left with no pay at all,” Aoki said.

Former wrestling promoter Seiji Sasa, 67 has recruited Sendai’s homeless for more than two decades.

He said he earns about 100 dollars for every introduction, and many of his recent hires are likely to end up in a radioactive workplace but that he didn’t ask questions.

“I don’t ask any questions, that’s not my job. I just find people and send them to work. I send them and get money in exchange. That’s it. I don’t get involved in what happens after that,” Sasa said.

“As a broker, it’s thanks to homeless people that I’ve been able to eat. I introduce them to work, receive money in return, and make my living. If what I did killed homeless people, then I’d be out of a job,” he added.

For Nishiyama, radiation is the last thing on his mind. He just wants to make it through the winter and prepare his cardboard box against the cold of the nights to come.

This Reuters report forgets to mention that recruiting these homeless people as nuclear radiation cannon fodder is done by Yakuza gangsters. This other Reuters report does mention that.

Radiation levels exceeding state-set limit found on grounds of five Chiba schools

Jun 13, 2017

Radiation levels exceeding the government-set safety limit of 0.23 microsieverts per hour have been detected on the grounds of five schools in the city of Kashiwa, Chiba Prefecture, the prefectural board of education said Monday.

Between late April and mid-May, the board officials detected radiation levels of up to 0.72 microsieverts per hour in certain areas of the schools, including Kashiwa High School and Kashiwa Chuo High School. The areas — including soil near a school swimming pool and drainage gutters — are not frequented by students, but the board closed them off and will work to quickly decontaminate them, the officials said.

Kashiwa has been one of the areas with high radiation readings since the 2011 nuclear disaster at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 power plant.

According to NHK, the board of education had been checking the soil on the school premises in Kashiwa after radiation levels beyond the state limit were detected in shrubbery near the city’s public gymnasium. The board will announce the results of radiation tests at other schools in the prefecture around the end of July, NHK reported.

Fukushima, Japan nuclear disaster news


This video from Japan says about itself:

3 February 2017

Radiation inside the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear plant measures as high as a deadly 530 sieverts per hour, the highest since the 2011 disaster, plant operator Tokyo Electric Power Co. (TEPCO) announced on Feb. 2.

TEPCO calculated the radiation dose from video noise on footage it took inside the containment vessel in late January, when a camera was inserted to examine conditions inside and scout a route for a scorpion-like observation robot scheduled to go into the vessel later this month.

Deployment of the robot is also being reconsidered after two gaping holes were found along the robot’s planned path over a 5-meter-wide circular walkway inside the containment vessel, close to where the 530-sievert radiation dose was detected.

The holes in the metal grate walkway — one of unknown size and the other measuring about 1 meter square — make both routes considered for the robot impassable.

Six years after Fukushima, much of Japan has lost faith in nuclear power … Six years have passed since the Fukushima nuclear disaster on March 11, 2011, but Japan is still dealing with its impacts. Decommissioning the damaged Fukushima Daiichi nuclear plant poses unprecedented technical challenges. More than 100,000 people were evacuated but only about 13 percent have returned home, although the government has announced that it is safe to return to some evacuation zones: here.

From the Asia Times:

Six years after Japan’s Fukushima nuclear accident three global nuclear corporations are fighting for their very survival.

The bankruptcy filing by Westinghouse Electric Co. and its parent company Toshiba Corp. preparing to post losses of ¥1 trillion (US$9 billion), is a defining moment in the global decline of the nuclear power industry.

However, whereas the final financial meltdown of Westinghouse and Toshiba will likely be measured in a few tens of billions of dollars, those losses are but a fraction of what Tokyo Electric Power Co. (Tepco) is looking at as a result of the Fukushima nuclear disaster.

Japan: Fukushima cancer kid missing from official files

Saturday 1st April 2015

A CHILD who was diagnosed with thyroid cancer after a meltdown at Japan’s Fukushima Dai-ichi nuclear plant is missing from government check-up data, medical workers warned yesterday.

The 3.11 Fund for Children With Thyroid Cancer, named after the date of the March 11 2011 disaster, said that the four-year-old is missing from a list of 184 cases of thyroid cancer in Fukushima.

Government officials claim that no-one younger than five got the cancer after the nuclear meltdown.

Dr Hisako Sakiyama, a fund representative, said that the missing record was alarming.

The boy, now 10, is receiving treatment at Fukushima Medical University, so she said it was inconceivable the university — which compiled the list — was unaware of the case.
