The mass media have barely noticed the tenth anniversary of the meltdown of the Fukushima reactors, apart from a handful of tepid ‘reports’ that avoid any mention of the far-reaching and ongoing disaster. This article is a refreshing, and important, exception.
Fukushima at Ten: Aftershocks, Lies and Failed Decontamination
by John LaForge
It’s now 10 years since the catastrophic triple meltdowns of reactors at Fukushima in Japan. As Joseph Mangano of the Radiation and Public Health project put it three years ago, “Enormous amounts of radioactive chemicals, including caesium, strontium, plutonium, and iodine were emitted into the air, and releases of the same toxins into the Pacific have never stopped, as workers struggle to contain over 100 cancer-causing chemicals.”
There is news of the shortage of Fukushima health studies, big earthquakes (aftershocks) and typhoons rattling nerves, reactors and waste systems, novel radioactive particles dispersed, and corporate and government dishonesty about decontamination.
Very few health studies
“So far only one single disease entity has been systematically examined in humans in Fukushima: thyroid cancer,” says Dr Alex Rosen, the German chair of International Physicians for the Prevention of Nuclear War. Other diseases, such as leukemia or malformations, which are associated with increased radiation exposure, have not been investigated, Rosen told the German medical journal Deutsches Ärzteblatt March 2. (Five studies have focused not on disease, but on birth abnormalities in the areas most affected: three on infant mortality rates, one on underweight newborns, and one on declining birth rates 9 months after March 2011. * )
The one disease study of the population was a screening for thyroid cancer in 380,000 local children under the age 18. In January 2018, the journal Thyroid reported 187 cases after five years. A typical population of 380,000 children would produce 12 cases in five years, reported Joseph Mangano, director of the Radiation and Public Health Project. The increase among children is “exactly what would be expected if Fukushima were a factor, as radiation is most damaging to the fetus, infant and child,” Mangano said.
New Earthquakes Rattle Wreckage and Nerves
Another large earthquake, magnitude 7.3, struck Feb 13, again off the coast of the Fukushima reactor complex, and the reported 30 seconds of terror was followed by14 aftershocks up to magnitude 5.
The quake was severe enough that its Tokyo Electric Power Co. (Tepco) operators and federal regulators suspect it caused additional damage to reactors 1 and 3 where cooling water levels fell sharply, the Associated Press reported. The Feb 13 quake was felt in Tokyo 150 miles away. Japan's meteorological agency said it was believed to be an aftershock of the record 2011 quake.
At a Feb 15 meeting, government regulators said the quake had probably worsened existing earthquake damage in reactors 1 and 3 or broken open new cracks causing the cooling water level drop, the AP said.
“Because (the 2011 quake) was an enormous one with a magnitude of 9.0, it’s not surprising to have an aftershock of this scale 10 years later,” said Kenji Satake, a professor at the University of Tokyo’s Earthquake Research Institute.
There have been six major aftershocks in the Fukushima area since March 2011: April 7, 2011 (magnitude 7.1); April 11, 2011 (6.6); July 10, 2011 (7.0); Oct 26, 2013 (7.1); Nov 26, 2016 (6.9); and Feb 13, 2021 (7.3). All six of these earthquakes were named Fukushima in one language or another.
Earthquake shocks are not the only recurring nightmare to haunt the survivors of the record quake that killed 19,630. Typhoon Hagibis slammed into Tamura City in October 2019, and swept away an unknown number of bags of radioactive debris that had been stacked near a river.
Since March 2011, over 22 million cubic meters of contaminated soil, brush and other matter from areas hard hit by fallout has been collected in large black plastic bags and piled in temporary storage mounds in thousands of places. (“Fukushima residents fight state plan to build roads with radiation-tainted soil,” Koydo, Japan Times, Apr. 29, 2018) Yet the volume is the tip of the iceberg: According to R. Ramachandran, in The Hindu, January 31, 2020, “no decontamination activities are planned for the majority of forested areas which cover about 75 per cent of the main contaminated area of 9,000 square km.”
Cover-ups and disinformation
Reporting Feb 14 about the latest quake, the AP noted that Tepco “has repeatedly been criticised for cover-ups and delayed disclosures of problems.” On June 22 2016, Tepco's President Naomi Hirose publicly admitted that the company's lengthy refusal to speak of the “meltdowns” it knew of at its three reactors was tantamount to a cover-up and apologised for it.
The Washington Post reported March 6 2021 that “For years, Tepco claimed that the treated water stored at the plant contained only tritium, but data deep on its website showed that the treatment process had failed.” The tanks now hold almost 1.25 million tons of highly contaminated waste water. “In 2018, [Tepco] was forced to acknowledge that 70 percent of the water is still contaminated with dangerous radioactive elements — including strontium-90, a bone-seeking radionuclide that can cause cancer — and will have to be treated again before release,” the Post reported.
Harvey Wasserman reported for The Free Press on a July 2007 earthquake that shook Japan and forced dangerous emergency shutdowns at four reactors at Kashiwazaki. “For three consecutive days [Tepco] was forced to issue public apologies for erroneous statements about the severity of the damage done to the reactors, the size and lethality of radioactive spills into the air and water, the on-going danger to the public and much more. Once again, the only thing reactor owners can be trusted to do is to lie.”
Radioactive Particles Newly identified
Work just published in the journal Science of the Total Environment documents new, highly radioactive particles that were released from the destroyed Fukushima reactors. The study was led by Dr Satoshi Utsunomiya and Kazuya Morooka of Kyushu University. “Two of these particles have the highest caesium radioactivity ever measured for particles from Fukushima,” the research found. The study analyzed particles that were taken from surface soils collected 3.9 kilometers from the reactor site.
Speaking with Science Daily Feb 17, Dr Utsunomiya said, “Owing to their large size, the health effects of the new particles are likely limited to external radiation hazards during static contact with skin.” The particles were reportedly spewed by the hydrogen explosions that rocked the reactor buildings and fell within a narrow zone that stretches ~8 kilometers north-northwest of meltdowns.
But Dr Utsunomiya also said the long-lived radioactivity of cesium in “the newly found highly radioactive particles has not yet decayed significantly. As such, they will remain in the environment for many decades to come, and this type of particle could occasionally still be found in radiation hot spots.”
Smaller radioactive particles of uranium, thorium, radium, caesium, strontium, polonium, tellurium and americium were found afloat throughout Northern Japan, according to a report by Arnie Gundersen and Marco Kaltofen published July 27, 2017 in Science of the Total Environment.The radioactively hot particles were found in dusts and soils from Northern Japan. About 180 particulate matter samples were taken from automobile or home air filters, outdoor surface dust, and vacuum cleaner bags. Some 142 of the samples (about 80 percent) contained caesium-134 and cesium-137 which emit intense beta radiation and is very dangerous if ingested or inhaled. “A majority of these samples were collected from locations in decontaminated zones cleared for habitation by the National Government of Japan,” the authors revealed.
Greenpeace Reports Cleanup Failures and Deception
Greenpeace Japan released two major reports March 4 that also contradict the country’s positive decontamination and human rights claims after 2011.
“Successive governments during the last 10 years … have attempted to perpetrate a myth about the nuclear disaster. They have sought to deceive the Japanese people by misrepresenting the effectiveness of the decontamination program and ignoring radiological risks,” said Shaun Burnie, Senior Nuclear Specialist at Greenpeace East Asia and co-author of the first report.
Key findings of the radiation report Fukushima 2011-2020 are:
- Most of the 840 square kilometer Special Decontamination Area (SDA), where the government is responsible for decontamination, remains contaminated with radioactive cesium … an overall average of only 15% has been decontaminated.
- No long-term decontamination target level will be achieved in many areas. Citizens will be subjected for decades to radiation exposures in excess of the … recommended maximum.
- In the areas where evacuation orders were lifted in 2017, specifically Namie and Iitate, radiation levels remain above safe limits, potentially exposing the population to increased cancer risk.
Key findings of The Fukushima Daiichi Nuclear Power Station decommissioning report are:
- The current decommissioning plan in the timeframe of 30-40 years is impossible to achieve and is illusory.
- Radioactive waste created at the site should not be moved. Fukushima Daiichi is already and should remain a nuclear waste storage site for the long term.
