Fukushima’s Radiation Will Poison Food “for Decades,” Study Finds

Screen-Shot-2017-06-22-at-7.31.40-AM

Three of the six reactors at Japan’s Fukushima-Daiichi complex were wrecked in March 2011 by an earthquake and tsunami. The destruction of emergency electric generators caused a “station blackout” which halted cooling water intake and circulation. Super-heated, out-of-control uranium fuel in reactors 1, 2, and 3 then boiled off cooling water, and some 300 tons of fuel “melted” and burned through the reactors’ core vessels, gouging so deep into underground sections of the structure that to this day operators aren’t sure where it is. Several explosions in reactor buildings and uncovered fuel rods caused the spewing of huge quantities of radioactive materials to the atmosphere, and the worst radioactive contamination of the Pacific Ocean ever recorded. Fukushima amounts to Whole-Earth poisoning.

Now, researchers say, radioactive isotopes that were spread across Japan (and beyond) by the meltdowns will continue to contaminate the food supply for a very long time.

According to a new study that focused on “radiocaesium” — as the British call cesium-134 and cesium-137 — “food in japan will be contaminated by low-level radioactivity for decades.” The official university announcement of this study neglected to specify that Fukushima’s cesium will persist in the food chain for thirty decades. It takes 10 radioactive half-lives for cesium-137 to decay to barium, and its half-life is about 30 years, so C-137 stays in the environment for roughly 300 years.

The study’s authors, Professor Jim Smith, of the University of Portsmouth, southwest of London, and Dr. Keiko Tagami, from the Japanese National Institute of Radiological Sciences, report that cesium-caused “radiation doses in the average diet in the Fukushima region are very low and do not present a significant health risk now or in the future.”

This phraseology deliberately conveys a sense of security — but a false one. Asserting that low doses of radiation pose no “significant” health risk sounds reassuring, but an equally factual framing of precisely the same finding is that small amounts of cesium in food pose a slightly increased risk of causing cancer.

This fact was acknowledged by Prof. Smith in the June 14 University of Portsmouth media advisory that announced his food contamination study, which was published in Science of the Total Environment. Because of above-ground atom bomb testing, Prof. Smith said, “Radioactive elements such as caesium-137, strontium-90 and carbon-14 contaminated the global environment, potentially causing hundreds of thousands of unseen cancer deaths.”

No less an authority than the late John Gofman, MD, Ph.D., a co-discoverer of plutonium and Professor Emeritus of molecular and cell biology at the University of California, spent 50 years warning about the threat posed by low doses of radiation. In May 1999, Gofman wrote, “By any reasonable standard of biomedical proof, there is no safe dose, which means that just one decaying radioactive atom can produce permanent mutation in a cell’s genetic molecules. My own work showed this in 1990 for X rays, gamma rays, and beta particles.”

The Fukushima-borne cesium in Japan’s food supply, and in the food-web of the entire Pacific Ocean, emits both beta and gamma radiation. Unfortunately, it will bio-accumulate and bio-concentrate for 300 years, potentially causing, as Dr. Gofman if not Dr. Smith might say, hundreds of thousands of unseen cancer deaths.

Plutonium in Workers’ Urine


The Asahi Shimbun is reporting that, contrary to the reassurances made a few days ago by the Japan Atomic Energy Agency (see here), workers at JAEA’s Oarai Research and Development Center, WERE internally contaminated by Plutonium:

Plutonium found in urine of 5 workers in Ibaraki accident. THE ASAHI SHIMBUN, June 20, 2017 http://www.asahi.com/ajw/articles/AJ201706200039.html

Minute amounts of plutonium have been detected in the urine samples of all five workers who were accidentally exposed to radioactive plutonium at Japan Atomic Energy Agency (JAEA)’s Oarai Research and Development Center in Oarai, Ibaraki Prefecture, on June 6…. While maintaining the level of exposure the five workers experienced “would not have immediate effect on their health for a few months,” Akashi said their internal exposure levels are “relatively high for cases occurring in Japan as far as I know.”… 

…In urine testing, NIRS said it can detect smaller amounts of plutonium as the measurement time is much longer, while the smallest radiation doses the dosimeter for lungs can detect is between 5,000 and 10,000 bequerels.

I shouldn’t be too critical of these oscillating reports given the US won’t even admit when its workers are contaminated with Plutonium, as the recent tunnel collapse at Hanford reminds us:

Tia Ghose. May 10, 2017. Hanford Disaster: What Happens to Someone Who’s Exposed to Plutonium? Live Science, https://www.livescience.com/59042-how-does-plutonium-damage-the-body.html

Workers at a nuclear-waste site in Washington state were recently told to hunker down in place after a tunnel in the nuclear finishing plant collapsed, news sources reported yesterday (May 9)…

The tunnel was part of the plutonium and uranium extraction facility (PUREX) said to be holding a lot of radioactive waste, including railway cars used to carry spent nuclear fuel rods, news agency AFP reported. At least some of the radioactive waste at the Hanford facility contains radioactive plutonium and uranium, according to the DOE, although at least some of it is also radioactive “sludge” composed of a mixture of radioactive substances. Right now, authorities have not revealed whether radioactive substances have been released or whether people have been exposed any of these contaminants

Governments don’t want to talk too much to the public about plutonium. Every dimension of knowledge about this element seems to be weaponized. Despite the desire for secrecy, plutonium always seems to be out of bounds, contaminating some people or environment, or perhaps all people, especially men’s testes (see here).

Plutonium’s astonishing level of chemical toxicity and atomic instability are fetishized by the atomic priesthood, but the priesthood cannot control their Frankensteinan creation, as these stories and ongoing atmospheric emissions at Fukushima Daiichi demonstrate:

Plutonium in workers’ urine at Oarai Research and Development Center

Traces of plutonium in workers’ urine

Doctors say extremely small quantities of radioactive substances have been detected in the urine of 5 workers who were accidentally exposed to the materials early this month at a research facility north of Tokyo.

The incident took place on June 6th at a facility of the Japan Atomic Energy Agency in Oarai Town, Ibaraki Prefecture. The workers were inspecting a nuclear fuel container when a bag inside suddenly burst, expelling radioactive powder.

The agency initially said as much as 22,000 becquerels of plutonium-239 were detected in the lungs of one of the workers. But they were discharged from hospital by Tuesday of last week after repeated examinations at the National Institute of Radiological Sciences detected no plutonium in their lungs.

On Monday, the institute said checks of the 5 workers’ urine later revealed extremely small amounts of plutonium and other radioactive materials.

It says the workers have so far suffered no damage to their health, but that they have reentered hospital to take medicines that will purge the plutonium from their bodies. They will take the drug for 5 days, after which doctors will decide if further medication is necessary.

An official related to the institute says the radioactive materials in the workers’ bodies are at levels that will not immediately affect their health.

Meanwhile, the Japan Atomic Energy Agency, which employs the 5 workers, on Monday submitted to the country’s nuclear regulator an interim report on how the accident unfolded.

The agency’s president, Toshio Kodama, told reporters that he apologizes to the public for the incident. Kodama added that his organization may have problems sensing and foreseeing risks.

Kodama said the agency has to work on organizational issues, including worker awareness.

The agency says it plans to conduct a detailed investigation into the cause of the accident. It says it will consider measures to prevent recurrences and report to the regulator.

Tokyo, June 19 (Jiji Press)–Trace amounts of plutonium have been detected in the urine of all five workers exposed to radioactive materials at a nuclear research facility in eastern Japan earlier this month, a radiological research center treating them said Monday.
The radioactive substances detected in the urine were plutonium-239, plutonium-238 and americium-241, the National Institute of Radiological Sciences, or NIRS, said.
The results showed that the workers at the Japan Atomic Energy Agency’s Oarai Research and Development Center in Ibaraki Prefecture, northeast of Tokyo, suffered internal radiation exposure, the NIRS said.
The NIRS plans to continue examining the five workers for about a month to estimate levels of exposure.
The exposure is unlikely to reach levels that cause symptoms, said Makoto Akashi, a senior official at the National Institutes for Quantum and Radiological Science and Technology, which oversees the NIRS.

Plutonium found in urine of 5 workers in Ibaraki accident

Minute amounts of plutonium have been detected in the urine samples of all five workers who were accidentally exposed to radioactive plutonium at Japan Atomic Energy Agency (JAEA)’s Oarai Research and Development Center in Oarai, Ibaraki Prefecture, on June 6.

The test results were announced June 19 at a news conference by the National Institute of Radiological Sciences (NIRS) within National Institutes for Quantum and Radiological Science and Technology (QST).

The revelation marks the latest twist in the changing assessment of severity of the health risks in the accident. Initially JAEA announced on June 7 that one of the five workers had suffered an internal exposure of 22,000 bequerels during an inspection at the nuclear energy research center. On June 9, JAEA said no plutonium was detected in any of the five workers’ lungs in further testing by NIRS.

Makoto Akashi, an executive of QST, said at the news conference the latest finding confirmed that the workers did “suffer an internal exposure.”

While maintaining the level of exposure the five workers experienced “would not have immediate effect on their health for a few months,” Akashi said their internal exposure levels are “relatively high for cases occurring in Japan as far as I know.”

He also added that long-term observation may be necessary depending on the level of internal exposure.

JAEA’s initial “internal exposure of 22,000 bequerels” assessment was hastily done on the night of the accident on June 6. The five workers were examined using a dosimeter that can detect small traces of X-rays emitted by plutonium particles inhaled into the lungs.

However, the next day, NIRS staff discovered that four of the workers did not have all the plutonium on their bodies completely removed. After thorough decontamination efforts, they were retested for plutonium in the lungs, which was “not detected.”

It is believed the initial assessment came back with a high reading, as the dosimeter also picked up the radiation from the plutonium residue on their bodies.

In urine testing, NIRS said it can detect smaller amounts of plutonium as the measurement time is much longer, while the smallest radiation doses the dosimeter for lungs can detect is between 5,000 and 10,000 bequerels.

The latest test result suggests the possibility that some plutonium particles inhaled into the workers’ lungs have been absorbed into the bloodstream, then discharged into the urine.

The five workers had been discharged and are in stable condition, but were readmitted to the institution for further treatment on June 18. They started receiving medication via intravenous drip injections to speed the excretion of radioactive substances in their bodies from June 19, according to NIRS.

It is the second time they have received this medication. NIRS confirmed the treatment’s effectiveness as the amount of plutonium in their urine increased after the first round of injections compared to the amount found prior to receiving the drug.

New South Korean president vows to end use of nuclear power

Moon Jae-in said he would lead country towards a ‘nuclear-free era’ following fears of a Fukushima-style meltdown

4967.jpgMoon Jae-in speaks at an event to mark the closure of South Korea’s oldest nuclear plant, Kori-1.

 

South Korea’s new president, Moon Jae-in, has vowed to phase out the country’s dependence on nuclear power, warning of “unimaginable consequences” from a Fukushima-style meltdown.

Moon, a left-leaning liberal who won last month’s presidential election by a landslide following the impeachment and arrest of Park Geun-hye, said he would increase the role of renewable energy and lead South Korea towards a “nuclear-free era”.

Speaking at an event to mark the closure of the country’s oldest nuclear plant, Kori-1, he said: “So far, South Korea’s energy policy pursued cheap prices and efficiency. “Cheap production prices were considered the priority while the public’s life and safety took a back seat. But it’s time for a change.

We will abolish our nuclear-centred energy policy and move towards a nuclear-free era. We will completely scrap construction plans for new nuclear reactors that are currently under way.”

Moon added that he would not extend the operation of ageing reactors, many of which will come to the end of their lifespans between 2020 and 2030.

Weaning South Korea off nuclear power, however, could take decades, and there is expected to be opposition from construction companies, which have increased technology exports under Moon’s nuclear-friendly predecessors.

The country was the fifth-largest producer of nuclear energy last year, according to the World Nuclear Association, with its 25 reactors generating about a third of its electricity.

The former president Lee Myung-bak saw nuclear as an important source of clean energy, while Park wanted to increase the number of reactors to 36 by 2029.

Moon recognised the role of nuclear power in South Korea’s rapid economic development, but added that Japan’s Fukushima disaster – which prompted the evacuation of tens of thousands of people – had convinced him that his country must look to new sources of energy.

The country’s economic status has changed, our awareness on the importance of the environment has changed. The notion that the safety and lives of people are more important than anything else has become a firm social consensus,” he said.

Anti-nuclear campaigners have long warned of the potentially disastrous consequences of a meltdown at a nuclear plant in South Korea, where many reactors are close to densely populated areas.

The public’s support for nuclear power has weakened since the 2011 Fukushima meltdown and a 2013 corruption scandal over fake safety certificates for reactor parts.

The Fukushima nuclear accident has clearly proved that nuclear reactors are neither safe, economical nor environmentally friendly,” Yonhap news agency quoted Moon as saying.

South Korea is not safe from the risk of earthquakes, and a nuclear accident caused by a quake can have such a devastating impact.”

He also plans to close at least 10 ageing coal-fired power plants before his term ends in 2022 and to boost renewables’ share of the energy mix to 20% by 2030.

Denuclearization Started by the Newly Elected South Korea’s Administration

South Korea’s administration has learned well from Japan’s Fukushima Daiichi nuclear disaster, whereas Japan’s administration is still living in denial orchestrating cover-up and lies.

 

southkoreacu.jpgSouth Korea currently operates 25 nuclear reactors, which generate about 30 percent of the country’s power supply

 

S. Korea to scrap all plans to build new nuclear reactors


South Korea’s new President Moon Jae-In vowed on Monday to scrap all plans to build new nuclear reactors as he seeks to steer Asia’s fourth-largest economy clear of atomic power.

Moon, who swept to power with a landslide election win last month, campaigned on promises to phase out atomic energy and embrace what he says are safer and more environmentally-friendly power sources including solar and wind power.

The Fukushima nuclear meltdown in Japan sparked by a powerful earthquake in March 2011 sparked widespread public concern in neighbouring South Korea over its own aged atomic plants.

“We will dump our atomic-centric power supply and open the door to the post-nuclear era,” Moon said in a speech marking the decommissioning of the country’s first nuclear reactor, the Kori-1.

“I will scrap all preparations to build new reactors currently underway and will not extend lifespan of current reactors,” he said.

Many reactors are located dangerously close to residential areas in the densely-populated nation, Moon said, warning of “unimaginable consequences” in case of a nuclear meltdown.

“South Korea is not safe from the risk of earthquake, and a nuclear accident caused by a quake can have such a devastating impact,” he said.

South Korea currently operates 25 nuclear reactors, which generate about 30 percent of the country’s power supply.

Many of them will see their lifespans expire between 2020 to 2030, with decisions on whether to extend some of their operations set to be made during Moon’s 2017-2022 term.

Moon, during his presidential campaign, vowed to try to eventually shut down all nuclear power plants across the country, although doing so will likely take decades.

Major corruption scandals involving state nuclear power agencies in recent years and a series of earthquakes last year further fanned public distrust and concerns over the safety of the plants.

Moon on Monday also vowed to decommission “as soon as possible” another aged atomic plant in the southeast, whose original 30-year lifespan had been extended by another decade to 2022.

He also vowed to introduce “post-coal” policy in line with his campaign promise to abandon coal power to ease air pollution in the country, which has the highest level of small air pollutant particles among OECD member nations.

But experts say shutdown of coal power plants could dramatically hike utility cost in the country where coal power generates about 40 percent of entire power needs.

Korea’s oldest nuclear reactor ceases operation

Kori No. 1, South Korea’s oldest nuclear reactor located in Busan, ceased operation Sunday at midnight after four decades.

Its operator Korea Hydro and Nuclear Power Co. said that it cut the power supply Saturday and began the cooling-down process of the reactor.

20170618000189_0.jpgKori No.1, South Korea’s first and the oldest nuclear reactor is seen in southern city of Busan.

 

It was officially decommissioned, with the temperature of the reactor gradually dropping to 90 degrees Celsius, from its normal operation at 300 degree Celsius, the KHNP said. Officials will then relocate the spent nuclear fuel stored inside the rector to a liquid sodium-cooled reactor for reprocessing.

The actual dismantling of the facilities is expected to start no later than 2022. The KHNP expects that at least 634 billion won ($559 million) is required for the dismantling. They also need to submit a dismantlement plan within five years for the NCCS’ approval.

The state-run Nuclear Safety and Security Commission, which approved earlier this month the permanent shutdown of Kori No. 1, said it will continue to check the safety management of the suspended reactor on a regular basis until the dismantlement.

Following the government’s approval in 2007, Kori No. 1’s operation was extended by 10 years after a 30-year run.

Some experts oppose the planned reprocessing of nuclear waste, saying the technology, though effective in reducing the volume of waste, could complicate waste disposal by creating different types of radioactive waste.

Under President Moon Jae-in, the South Korean government aims to close all nuclear power plants by shutting down aged facilities and eventually phasing out the rest over the next 40 years.

Korea’s first nuclear plant suspended after 40 years of operation

Built as Korea’s first nuclear power plant at Gijang County, Busan, Gori-1 came to a halt after completing its four decades of service, providing electricity since 1978. Gori-1 ended its chapter in the history of Korean nuclear power generation, being the first-ever nuclear powerhouse and the first of its kind to be out of service for good.

The Nuclear Safety and Security Commission (NSSC) opened its 70th meeting on Friday and announced that it has approved the permanent suspension of Gori-1, requested by the Korea Hydro and Nuclear Power (KHNP) last June. Under the recent approval, KHNP will stop operating the aged plant, and will cool nuclear fuels as of midnight on June 19. KHNP plans to dissemble the plant in earnest starting in 2022.

Gori-1 opened an era of commercial nuclear power generation in Korea on April 29, 1978. Meeting the rapidly increasing power demands amid economic growth, it has layed grounds for the nation to develop into an industrial state. While it reached its design life (30 years) in June 2007, the plant was resuscitated and was operated for an additional 10 years after undergoing full repair and consensus with residents.

Some view the first permanent suspension of a Korean nuclear plant as the first step towards denuclearization by the new administration. During his campaign, President Moon Jae-in pledged to immediately close down outdated nuclear plants and reduce nuclear power generation. Under the recent decision made by NSSC, experts view that the extension policy for the lifecycle of a nuclear plant will be set as “once for 10 years.” KHNP will hold a ceremony to celebrate the permanent halt of Gori-1 on June 19.

Plutonium found in urine of 5 workers exposed to radiation

94 Plutonium-300x300.jpg

TOKYO (Kyodo) — A small amount of plutonium was found in the urine of five workers exposed to radiation in an accident earlier this month at a nuclear research facility in Ibaraki Prefecture, a hospital operator said Monday.

The result shows that the five workers have suffered internal radiation exposure following the June 6 accident at the Japan Atomic Energy Agency’s Oarai Research & Development Center in the coastal town of Oarai.

They had been receiving medication to facilitate the discharge of radioactive materials from their bodies since the accident and will continue to do so, said the National Institutes for Quantum and Radiological Science and Technology, the operator of the hospital.

The five, although showing no signs of deterioration or notable change in their health, were hospitalized again from Sunday for the treatment.

In the accident, radioactive materials were released into the air in the room where the five were working when one opened a metal container holding plutonium and uranium powder samples and a plastic bag containing the samples inside suddenly ruptured.

Initially, the agency said up to 22,000 becquerels of plutonium-239 were found in the lungs of one of the five workers, while up to 5,600 to 14,000 becquerels of the radioactive substance were found in the lungs of three other workers. It said at the time that the four had suffered internal radiation exposure.

But the facility operator has since said a subsequent check by the National Institute of Radiological Sciences has found no plutonium in the lungs of any of the five workers. It has not ruled out the possibility that what was actually detected was radioactive substance left on the workers’ bodies after decontamination.

Also on Monday, JAEA President Toshio Kodama again apologized over the accident, saying at a press conference, “The agency as a whole had problems in the prediction of risks.”

He said he has no intention of resigning for now but will take “appropriate” responsibility depending on the cause of the accident.

The agency submitted a report compiling the causes of the accident and measures to be taken to prevent a recurrence to the Nuclear Regulation Authority, the state’s nuclear safety watchdog.

For Fukushima returnees, security a growing concern in deserted towns

n-fukushimafile-a-20170619-870x577.jpgThe deserted streets of the town of Namie, Fukushima Prefecture, are seen at night after its evacuation order was lifted in this undated photo.

 

Via Fukushima Minpo –  It’s like a dream to once again be able to live in my “home, sweet home.”

That’s what Hidezo Sato, 72, says he feels every day since returning to his fallout-hit hometown of Namie, Fukushima Prefecture.

The government partially lifted its nuclear evacuation order on March 31, six years after radiation from the triple meltdown at the Fukushima No. 1 nuclear power plant forced them to evacuate.

Now, friends come by to chat at his home in the Gongendo district, which is much more comfortable than where he spent the past six years living as a Fukushima evacuee.

But one thing still bugs him — he doesn’t feel safe at night.

According to town officials, only about 300 residents have come back so far.

Many of the houses in Sato’s neighborhood remain uninhabited. So when he spots a car parked in the dark, it frightens him.

If safety and security aren’t ensured, there won’t be more people coming back,” Sato said.

Sparked by returnees’ concerns about security, many recovering municipalities have set up neighborhood watch groups, installed security cameras and taken other measures to increase safety.

In December, two men were arrested on theft charges after spotted by security cameras.

In Minamisoma, City Hall is installing home security systems for returnees in the Odaka district that allow them to alert a security company simply by pushing a button. As of April 27, about 240 households, or 30 percent of the roughly 770 households that have returned, had the system installed by the city.

The number of police officers brought in from outside Fukushima to help patrol the no-go zone has been reduced to 192, or about 150 fewer than five years ago. The police presence is expected to decline further as decontamination progresses, raising concerns on how to ensure security there in the future.

Many municipalities have been funding security costs with central government subsidies, but it is unclear whether that will continue after fiscal 2020, when the state-designated reconstruction and revitalization period is scheduled to end. The Reconstruction Agency is also slated to be dissolved by then.

A top Reconstruction Agency official would only say it will “consider the issue in the future.”

For its part, the town of Namie is expected to spend about ¥700 million in fiscal 2017 to fund the neighborhood watch teams and surveillance systems. But town officials are worried whether they’ll be able to afford the systems once the subsidies dry up.

Reconstruction minister Masayoshi Yoshino, a Lower House politician representing the Fukushima No. 5 district, said in April that he will consider creating a new government entity to take over the work of the Reconstruction Agency.

I want the government to tell us that it will continue to fund” such projects, said Namie Deputy Mayor Katsumi Miyaguchi.
