Radioactive hot particles still afloat throughout Japan six years after Fukushima meltdowns — BuzzFlash

” Radioactive particles of uranium, thorium, radium, cesium, strontium, polonium, tellurium and americium are still afloat throughout Northern Japan more than six years after a tsunami slammed into the Fukushima Daiichi Power Plant causing three full-blown nuclear meltdowns. That was the conclusion reached by two of the world’s leading radiation experts after conducting an extensive five-year monitoring project.

Arnie Gundersen and Marco Kaltofen authored the peer reviewed study titled, Radioactively-hot particles detected in dusts and soils from Northern Japan by combination of gamma spectrometry, autoradiography, and SEM/EDS analysis and implications in radiation risk assessment, published July 27, 2017, in Science of the Total Environment (STOLEN).

Gundersen represents Fairewinds Associates and is a nuclear engineer, former power plant operator and industry executive, turned whistleblower, and was CNN’s play-by-play on-air expert during the 2011 meltdowns. Kaltofen, of the Worcester Polytechnic Institute (WPI), is a licensed civil engineer and is renowned as a leading experts on radioactive contamination in the environment.

415 samples of “dust and surface soil” were “analyzed sequentially by gamma spectrometry, autoradiography, and scanning electron microscopy with energy dispersive X-ray analysis” between 2011 and 2016. 180 of the samples came from Japan while another 235 were taken from the United States and Canada. The study further clarifies, “Of these 180 Japanese particulate matter samples, 57 were automobile or home air filters, 59 were surface dust samples, 29 were street dusts (accumulated surface soils and dusts) and 33 were vacuum cleaner bag or other dust samples.”

108 of the Japanese samples were taken in 2016, while the other 72 were gathered in 2011 after the meltdowns. Gundersen and Kaltofen tapped 15 volunteer scientists to help collect the dust and soil — mostly from Fukushima Prefecture and Minamisoma City. “A majority of these samples were collected from locations in decontaminated zones cleared for habitation by the National Government of Japan,” the study revealed. For the 108 samples taken in 2016, an “International Medcom Inspector Alert surface contamination monitor (radiation survey meter) was used to identify samples from within low lying areas and on contaminated outdoor surfaces.”

Fairewinds Associates’ video from 2012 features Gundersen collecting five samples of surface soil from random places throughout Tokyo — places including a sidewalk crack, a rooftop garden, and a previously decontaminated children’s playground. The samples were bagged, declared through Customs, and brought back to the U.S. for testing. All five samples were so radioactive that according to Gundersen, they “qualified as radioactive waste here in the United States and would have to be sent to Texas to be disposed of.” Those five examples were not included as part of the recently released study, but Gundersen went back to Tokyo for samples in 2016. Those samples were included, and were radioactive, and according to Gundersen were “similar to what I found in Tokyo in [2012].”

Furthermore, 142 of the 180 samples (about 80 percent) contained cesium 134 and cesium 137. Cesium 134 and 137, two of the most widespread byproducts of the nuclear fission process from uranium-fueled reactors, are released in large quantities in nuclear accidents. Cesium emits intense beta radiation as it decays away to other isotopes, and is very dangerous if ingested or inhaled. On a mildly positive note, the study shows that only four of the 235 dust samples tested in the United States and Canada had detectable levels of cesium from Fukushima.

Cesium, due to its molecular structure, mimics potassium once inside the body, and is often transported to the heart where it can become lodged, thereafter mutating and burning heart tissue which can lead to cardiovascular disease. Other isotopes imitate nutritive substances once inside the body as well. Strontium 90 for example mimics calcium, and is absorbed by bones and teeth.

“Different parts of the human body (nerves, bones, stomach, lung) are impacted differently,” Kaltofen told EnviroNews in an email. “Different cells have radio-sensitivities that vary over many orders of magnitude. The body reacts differently to the same dose received over a short time or a long time; the same as acute or chronic doses in chemical toxicity.”

In contrast to external X-rays, gamma, beta or alpha rays, hot particles are small mobile pieces of radioactive elements that can be breathed in, drunk or eaten in food. The fragments can then become lodged in bodily tissue where they will emanate high-intensity ionizing radiation for months or years, damaging and twisting cells, potentially causing myriad diseases and cancer. The study points out, “Contaminated environmental dusts can accumulate in indoor spaces, potentially causing radiation exposures to humans via inhalation, dermal contact, and ingestion.”

The study also explains, “Given the wide variability in hot particle sizes, activities, and occurrence; some individuals may experience a hot particle dose that is higher or lower than the dose calculated by using averaged environmental data.” For example, a person living in a contaminated area might use a leaf blower or sweep a floor containing a hefty amount of hot particle-laden dust and receive a large does in a short time, whereas other people in the same area, exposed to the same background radiation and environmental averages, may not take as heavy a hit as the housekeeper that sweeps floors for a living. People exposed to more dust on the job, or who simply have bad luck and haphazardly breathe in hot radioactive dust, are at an increased risk for cancer and disease. High winds can also randomly pick up radioactive surface soil, rendering it airborne and endangering any unsuspecting subject unlucky enough to breath it in.

Hot particles, or “internal particle emitters” as they are sometimes called, also carry unique epidemiological risks as compared to a chest X-ray by contrast. The dangers from radiation are calculated by the dose a subject receives, but the manner in which that dose is received can also play a critical factor in the amount of damage to a person’s health.

“Comparing external radiation to hot particles inside the body is an inappropriate analogy,” Gundersen toldEnviroNewsin an email. “Hot particles deliver a lot of energy to a very localized group of cells that surround them and can therefore cause significant localized cell damage. External radiation is diffuse. For example, the weight from a stiletto high heal shoe is the same as the weight while wearing loafers, but the high heal is damaging because its force is localized.”

Kaltofen elaborated with an analogy of his own in a followup email with EnviroNews saying:

Dose is the amount of energy in joules absorbed by tissue. Imagine Fred with a one joule gamma dose to the whole body from living in a dentist’s office over a lifetime, versus Rhonda with exactly the same dose as alpha absorbed by the lung from a hot particle. Standard health physics theory says that Fred will almost certainly be fine, but Rhonda has about a 10 percent chance of dying from lung cancer — even though the doses are the same.

External radiation and internal hot particles both follow exactly the same health physics rules, even though they cause different kinds of biological damage. Our data simply shows that you can’t understand radiation risk without measuring both.

Some isotopes, like plutonium, only pose danger to an organism inside the body. As an alpha emitter, plutonium’s rays are blocked by the skin and not strong enough to penetrate deep into bodily tissue. However, when inhaled or ingested, plutonium’s ionizing alpha rays twist and shred cells, making it one of the most carcinogenic and mutagenic substances on the planet.

“Measuring radioactive dust exposures can be like sitting by a fireplace,” Dr. Kaltofen explained in a press release. “Near the fire you get a little warm, but once in a while the fire throws off a spark that can actually burn you.”

“We weren’t trying to see just somebody’s theoretical average result,” Kaltofen continued in the press release. “We looked at how people actually encounter radioactive dust in their real lives. [By] combining microanalytical methods with traditional health physics models… we found that some people were breathing or ingesting enough radioactive dust to have a real increase in their risk of suffering a future health problem. This was especially true of children and younger people, who inhale or ingest proportionately more dust than adults.”

“Individuals in the contaminated zone, and potentially well outside of the mapped contaminated zone, may receive a dose that is higher than the mean dose calculated from average environmental data, due to inhalation or ingestion of radioactively-hot dust and soil particles,” the study says in summation. “Accurate radiation risk assessments therefore require data for hot particle exposure as well as for exposure to more uniform environmental radioactivity levels.” ”

High levels of cesium radioactive material migrating down into soil around Fukushima — Global Research

” High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba, Japan.

In 2016, a team of more than 170 researchers from the Japanese Geoscience Union and the Japan Society of Nuclear and Radiochemical Sciences conducted a large-scale soil sampling project to determine the contamination status and transition process of radioactive cesium five years after a major earthquake and tsunami caused a nuclear accident at the Fukushima Daiichi plant.

The team collected soil samples at 105 locations up to 40 kilometers (25 miles) northwest of the Fukushima Daiichi nuclear power plant in the “difficult-to-return” zone where entry is prohibited. The project seeks to understand the chemical and physical forms of radionuclides in the soil and their horizontal and vertical distribution.

The Japanese government has monitored the state of radioactive contamination in the area near the plant since the 2011 accident by measuring the air dose rate, but scientists can only determine the actual state of contamination in the soil and its chemical and physical forms by direct soil sampling, said Kazuyuki Kita, a professor at Ibaraki University in Japan, who is one of the leaders of the soil sampling effort.

Understanding the radionuclides’ chemical and physical forms helps scientists understand how long they could stay in the soil and the risk they pose to humans, plants and animals, Kita said. The new information could help in assessing the long-term risk of the radionuclides in the soil, and inform decontamination efforts in heavily contaminated areas, according to Kita, one of several researchers will present the team’s preliminary results at the JpGU-AGU joint meeting next week.

Preliminary results show high levels radioactive cesium are still present in the soil near the plant. The levels of radiation are more than 90 percent, on average, of what was found immediately following the accident, according to Kita.

Most of the radiocesium in the soil was found near the surface, down to about 2 centimeters, immediately following the 2011 accident. Five years later, at several sampling points, one-third to one-half of the radiocesium has migrated deeper into the soil, according to Kita. Preliminary results show the radiocesium moved about 0.3 centimeters per year, on average, deeper into the soil and soil samples show the radiocesium has penetrated at least 5 centimeters into the ground at several areas, according to Kita.

The team plans to analyze samples taken at greater depths to see if the radiocesium has migrated even further, he said.

“Most of the radioactive cesium remains after five years, but some parts of the radioactive cesium went from the surface to deeper soil,” he said.

Knowing how much radioactive contamination has stayed on the surface and how deep it has penetrated into the soil helps estimate the risk of the contaminants and determine how much soil should be removed for decontamination. The preliminary results suggest decontamination efforts should remove at least the top 6 to 8 centimeters of soil, Kita said.

The preliminary data also show there are insoluble particles with very high levels of radioactivity on the surface of the soil. Debris from the explosion fused with radiocesium to form small glass particles a few microns to 100 microns in diameter that remain on the ground, according to Kita. The team is currently trying to determine how many of these radiocesium glass particles exist in areas near the nuclear plant, he said.

“We are afraid that if such high radioactive balls remain on the surface, that could be a risk for the environment,” Kita said. “If the radioactivity goes deep into the soil, the risk for people in the area decreases but we are afraid the high radioactive balls remain on the surface.” “

Japan considering using Fukushima soil for public parks — TRUNEWS

” The Japanese government may buy [contaminated soil], using soil from the Fukushima prefecture as landfill for “green areas” and parks, potentially subjecting citizens to dangerous radiation.

The advisory panel of the Environment Ministry on Monday proposed reusing soil that was contaminated during the Fukushima nuclear meltdown of 2011 as part of future landfills designated for public use, Kyodo news reported.

In its proposal, the environmental panel avoided openly using the word “park” and instead said “green space,” apparently to avoid a premature public outcry, Mainichi Shimbun reported.

Following an inquiry from the news outlet, the Ministry of the Environment clarified that “parks are included in the green space.”

In addition to decontaminating and recycling the tainted earth for new parks, the ministry also stressed the need to create a new organization that will be tasked with gaining public trust about the prospects of such modes of recycling.

To calm immediate public concerns, the panel said the decontaminated soil will be used away from residential areas and will be covered with a separate level of vegetation to meet government guidelines approved last year.

In June last year, the Ministry of the Environment decided to reuse contaminated soil with radioactive cesium concentration between 5,000 to 8,000 becquerels per kilogram for public works such as nationwide roads and tidal banks.

Under these guidelines, which can now be extended to be used for the parks, the tainted soil shall be covered with clean earth, concrete or other materials.

Such a landfill, the government said at the time, will not cause harm to nearby residents as they will suffer exposure less than 0.01 mSv a year after the construction is completed.

The Fukushima Daiichi nuclear power plant suffered a blackout and subsequent failure of its cooling systems in March 2011, when it was hit by an earthquake and a killer tsunami that knocked out the facility, spewing radiation and forcing 160,000 people to flee their homes. Three of the plant’s six reactors were hit by meltdowns, making the Fukushima nuclear disaster the worst since the Chernobyl catastrophe in 1986. ”

Fukushima radiation in the Pacific (revisited) — Triple Pundit

by RP Siegel

” My recent post on the spread of radiation stemming from the Fukushima nuclear accident drew quite a few questioning comments. Specifically the article suggested that radiation from the accident was drifting across the Pacific at levels high enough to cause alarm. It turns out such cause for alarm was exaggerated, though there is still reason to be concerned. I appreciate the feedback. I acknowledge that I relied on sources with which I was unfamiliar and posted some information that has been shown to be incorrect. I apologize.

To all who publish online, beware. Bad news travels fast. It gives credence to the old saying, “A lie can travel halfway around the world while the truth is still putting its pants on.” This is especially true on the Internet. I truly hope no one was harmed by this information. Now begins the task of earning back your trust which, though hard-earned, can be quickly lost.

I think the best way to start is to post a revised story on what is actually happening in the waters around Fukushima, Japan, as well as those farther afield.

Let’s start by addressing the points made in the original story.

For starters the initial source, PeakOil, used a bogus NOAA graphic to sensationalize the story, having carefully scrubbed out the legend showing that the colors actually represented wave heights at the peak of the tsunami, not radiation levels as the site would have you believe. I checked this image out, noticed this and chose not to use it in my post. Still, I continued to take the central thrust of the story as true.

Several people went to the generally reliable Snopes site to question the story and found confirmation of their suspicions. The blatant misuse of the NOAA chart is clearly called and tossed into the trash where it belongs. An interesting thing about the Snopes post, however, is that while the site prominently displays a text clipping stating that, “each day 300 tons of radioactive waste seeps into the ocean,” it never specifically addresses that claim.

I dug further and found that number actually comes from a quote by Yushi Yoneyama, an official with the Japanese Ministry of Economy, Trade and Industry, which oversees energy policy as quoted in Reuters (generally considered unassailable) and elsewhere. In 2013, Yoneyama said, “We think that the volume of water [leaking into the Pacific] is about 300 tonnes a day.” Of course, anyone could be wrong, but who am I to question Reuters or a Japanese government official? I don’t.

That’s not to say Japanese government officials, or officers of TEPCO, can always be counted on to tell the truth, but their interest has generally been to minimize the extent of the damage, not to embellish it.

As for that amount of leakage, that’s equivalent to about 90,000 gallons of radioactive water. That sounds like quite a bit. But compared to the volume of the Pacific Ocean, it’s not a lot at all. Still, when that much leaks out each day, over the course of a year, it adds up to 33 million gallons. And it’s been five years now.

Even today, TEPCO only acknowledges that radioactive water threatens to flood out of the plant and into the ocean. The company denied, until recently, that any water leaked from the plant at all, even when fish contaminated with high levels of radiation were found near the plant by independent researchers from the University of Tokyo, raising major concerns for local fishermen.

The story regarding radiation reaching the Canadian West Coast, which claimed levels of iodine-131 were 300 times background levels, was recently updated with an editor’s statement that the original figures were incorrect.

Reports of a wildlife biologist (Alexandra Morton) pulling hundreds of herring out of the waters off British Columbia with blood coming out of their eyes and gills have not been discredited. However, there is no evidence linking this observation directly to radiation from Fukushima or anywhere else.

The claim that radiation levels found in tuna off the Oregon coast had tripled also appears to be legitimate. However, those levels are still substantially below what would be considered a health threat.

Having sorted through that, I would summarize as follows: Contaminated water continues to enter to ocean from the Fukushima site in significant volume. Traces of radiation have been found in various locations around the Pacific. It also appears that the levels detected at this time do not indicate any immediate threat to humans outside of Japan. That being said, our knowledge of the long-term impacts of these types of radiation on the oceans, and on ourselves, is far from complete.

Upon review, most of the statements in the original piece were in fact true, but I acknowledge the overall sense was that of an exaggerated cause for concern. What this shows is how easily a group of facts taken out of context can become a convincing story — a lesson for all of us. Putting it on the Internet is like putting a match to a dry grassland.

What is far less clear is what the actual levels are and where they can be found. What makes writing about this issue so difficult, and even dangerous, is the combination of two things: It’s a frightening subject, and there is very little solid information being made available.

In my efforts to bring in some more solid facts, I reached out to Greenpeace, which is monitoring the situation carefully. The group sent me some additional information in a press release with links to reports published outside the U.S.

Greenpeace’s famed ship, the Rainbow Warrior, went out to sample the waters around Fukushima in February of this year with former Japanese Prime Minister Mr. Naoto Kan onboard. What they found was that radiation in the seabed off Fukushima “is hundreds of times above pre-2011 levels.” They also found levels in nearby rivers that were “up to 200 times higher than ocean sediment.”

Expressing concern, Ai Kashiwagi, energy campaigner for Greenpeace Japan, said: “These river samples were taken in areas where the Abe government is stating it is safe for people to live. But the results show there is no return to normal after this nuclear catastrophe.”

The areas sampled include the Niida River in Minami Soma, where readings measured as high as 29,800 becquerels per kilogram (Bq/kg) for radio-cesium. (For those new to the subject, a becquerel is a derived unit that measures radioactivity.) More samples taken at the estuary of the Abukuma River in Miyagi prefecture, more than 90 kilometers north of the Fukushima Daiichi plant, found levels in sediment as high as 6,500 Bq/kg. To put that in perspective, recorded levels in the seabed near the plant before the disaster were 0.65 Bq/kg.

Kendra Ulrich, senior global energy campaigner for Greenpeace Japan, explained: “The sheer size of the Pacific Ocean combined with powerful complex currents means the largest single release of radioactivity into the marine environment has led to the widespread dispersal of contamination.”

Greenpeace expressed concern that the order scheduled to allow people to return to these areas next March “cannot be permitted to stand.” The group claims that “these ecosystems cannot simply be decontaminated.”

Greenpeace’s report, which came out in July of this year, concludes by saying the impact of the accident will persist for “decades to centuries.”

So, while we have not yet seen the global-scale consequences some predicted, the situation is indeed bad and getting worse. TEPCO continues to build steel tanks at the rate of three per week, to house a great deal of contaminated groundwater while awaiting decontamination. But according to this PBS documentary, the company will run out of room for more tanks sometime next year. The gravity-fed water filtration system has been effective in removing most contaminants, except for tritium. Tritium is a relatively weak radionuclide with a half-life of 12.5 years, which means it will take about 100 years to fully break down.

The molten nuclear cores in reactors still remain in three reactors. And the site will not be fully stabilized until those are removed. But the radioactivity level in those reactors is far too high for people to enter. TEPCO plans to develop robots to go in and retrieve the molten fuel. The company says that retrieval is estimated to begin in 2020.

In closing, while the level of concern suggested in the prior piece was overstated, I maintain that the situation at Fukushima is far from resolved and that it remains a serious concern, particularly in Japan. I further maintain that any plans to continue expanding nuclear power must include an in-depth review of what has happened in Fukushima, with the understanding that this story is far from over. ”

Fukushima backlash hits Japan prime minister — CounterPunch

” Nuclear power may never recover its cachet as a clean energy source, irrespective of safety concerns, because of the ongoing saga of meltdown 3/11/11 at Fukushima Daiichi Nuclear Power Plant. Over time, the story only grows more horrific, painful, deceitful. It’s a story that will continue for generations to come.

Here’s why it holds pertinence: As a result of total 100% meltdown, TEPCO (Tokyo Electric Power Company) cannot locate or remove the radioactive molten core or corium from the reactors. Nobody knows where it is. It is missing. If it is missing from within the reactor structures, has it burrowed into the ground? There are no ready answers.

And, the destroyed nuclear plants are way too radioactive for humans to get close enough for inspection. And, robotic cameras get zapped! Corium is highly radioactive material, begging the question: If it has burrowed through the containment vessel, does it spread underground, contaminating farmland and water resources and if so, how far away? Nobody knows?

According to TEPCO, removing the melted cores from reactors 1,2 and 3 will take upwards of 20 years, or more, again who knows.

But still, Japan will hold Olympic events in Fukushima in 2020 whilst out-of-control radioactive masses of goo are nowhere to be found. TEPCO expects decades before the cleanup is complete, if ever. Fortunately, for Tokyo 2020 (the Olympic designation) radiation’s impact has a latency effect, i.e., it takes a few years to show up as cancer in the human body.

A week ago on September 7th, Former PM Junichiro Koizumi, one of Japan’s most revered former prime ministers, lambasted the current Abe administration, as well as recovery efforts by TEPCO. At a news conference he said PM Shinzō Abe lied to the Olympic committee in 2013 in order to host the 2020 Summer Olympics in Japan.

“That was a lie,” Mr Koizumi told reporters when asked about Mr Abe’s remark that Fukushima was “under control,” Abe Lied to IOC About Nuke Plant, ex-PM Says, The Straits Times, Sep 8, 2016. The former PM also went on to explain TEPCO, after 5 years of struggling, still has not been able to effectively control contaminated water at the plant.

According to The Straits Times article: “Speaking to the IOC in September 2013, before the Olympic vote, PM Abe acknowledged concerns but stressed there was no need to worry: “Let me assure you, the situation is under control.”

PM Abe’s irresponsible statement before the world community essentially puts a dagger into the heart of nuclear advocacy and former PM Koizumi deepens the insertion. After all, who can be truthfully trusted? Mr Koizumi was a supporter of nuclear power while in office from 2001-2006, but he has since turned into a vocal opponent.

Speaking at the Foreign Correspondents Club of Japan in Tokyo, Mr Koizumi said: “The nuclear power industry says safety is their top priority, but profit is in fact what comes first… Japan can grow if the country relies on more renewable energy,” (Ayako Mie, staff writer, Despite Dwindling Momentum, Koizumi Pursues Anti-Nuclear Goals, The Japan Times, Sept. 7, 2016).

Mr Koizumi makes a good point. There have been no blackouts in Japan sans nuclear power. The country functioned well without nuclear.

Further to the point of nuclear versus nonnuclear, Katsunobu Sakurai, mayor of Minamisoma, a city of 70,000 located 25 km north of Fukushima No. 1 nuclear plant, at a news conference in Tokyo, said: “As a citizen and as a resident of an area affected by the nuclear power plant disaster, I must express great anger at this act… it is necessary for all of Japan to change its way of thinking, and its way of life too – to move to become a society like Germany, which is no longer reliant on nuclear power,” (Sarai Flores, Minamisoma Mayor Sees Future for Fukushima ‘Nonnuclear’ City in Energy Independence, The Japan Times, March 9, 2016).

In March of 2015, Minamisoma declared as a Nonnuclear City, turning to solar and wind power in tandem with energy-saving measures.

Meanwhile, at the insistence of the Abe administration, seven nuclear reactors could restart by the end of FY2016 followed by a total of 19 units over the next 12 months (Source: Japanese Institute Sees 19 Reactor Restarts by March 2018, World Nuclear News, July 28, 2016).

Greenpeace/Japan Discovers Widespread Radioactivity

One of the issues surrounding the Fukushima incident and the upcoming Olympics is whom to trust. Already TEPCO has admitted to misleading the public about reports on the status of the nuclear meltdown, and PM Abe has been caught with his hand in the proverbial cookie jar, but even much worse, lying to a major international sports tribunal. His credibility is down the drain.

As such, maybe third party sources can be trusted to tell the truth. In that regard, Greenpeace/Japan, which does not have a vested interest in nuclear power, may be one of the only reliable sources, especially since it has boots on the ground, testing for radiation. Since 2011, Greenpeace has conducted over 25 extensive surveys for radiation throughout Fukushima Prefecture.

In which case, the Japanese people should take heed because PM Abe is pushing hard to reopen nuclear plants and pushing hard to repopulate Fukushima, of course, well ahead of the 2020 Tokyo Olympics since there will be events held in Fukushima Prefecture. After all, how can one expect Olympians to populate Fukushima if Japan’s own citizens do not? But, as of now to a certain extent citizens are pushing back. Maybe they instinctively do not trust their own government’s assurances.

But, more chilling yet, after extensive boots-on-the-ground analyses, Greenpeace issued the following statement in March 2016: “Unfortunately, the crux of the nuclear contamination issue – from Kyshtym to Chernobyl to Fukushima- is this: When a major radiological disaster happens and impacts vast tracts of land, it cannot be ‘cleaned up’ or ‘fixed’.” (Source: Hanis Maketab, Environmental Impacts of Fukushima Nuclear Disaster Will Last ‘decades to centuries’ – Greenpeace, Asia Correspondent, March 4, 2016).

That is a blunt way of saying sayonara to habitation on radioactive contaminated land. That’s why Chernobyl is a permanently closed restricted zone for the past 30 years.

As far as “returning home” goes, if Greenpeace/Japan ran the show rather than PM Abe, it appears they would say ‘no’. Greenpeace does not believe it is safe. Greenpeace International issued a press release a little over one month ago with the headline: Radiation Along Fukushima Rivers up to 200 Times Higher Than Pacific Ocean Seabed – Greenpeace Press Release, July 21, 2016.

Here’s what they discovered: “The extremely high levels of radioactivity we found along the river systems highlights the enormity and longevity of both the environmental contamination and the public health risks resulting from the Fukushima disaster,” says Ai Kashiwagi, Energy Campaigner at Greenpeace Japan.

“These river samples were taken in areas where the Abe government is stating it is safe for people to live. But the results show there is no return to normal after this nuclear catastrophe,” claims Kashiwagi.

“Riverbank sediment samples taken along the Niida River in Minami Soma, measured as high as 29,800 Bq/kg for radiocaesium (Cs-134 and 137). The Niida samples were taken where there are no restrictions on people living, as were other river samples. At the estuary of the Abukuma River in Miyagi prefecture, which lies more than 90km north of the Fukushima Daiichi plant, levels measured in sediment samples were as high as 6,500 Bq/kg” (Greenpeace).

The prescribed safe limit of radioactive cesium for drinking water is 200 Bq/kg. A Becquerel (“Bq”) is a gauge of strength of radioactivity in materials such as Iodine-131 and Cesium-137 (Source: Safe Limits for Consuming Radiation-Contaminated Food, Bloomberg, March 20, 2011).

“The lifting of evacuation orders in March 2017 for areas that remain highly contaminated is a looming human rights crisis and cannot be permitted to stand. The vast expanses of contaminated forests and freshwater systems will remain a perennial source of radioactivity for the foreseeable future, as these ecosystems cannot simply be decontaminated” (Greenpeace).

Still, the Abe administration is to be commended for its herculean effort to try to clean up radioactivity throughout Fukushima Prefecture, but at the end of the day, it may be for naught. A massive cleanup effort is impossible in the hills, in the mountains, in the valleys, in the vast forests, along riverbeds and lakes, across extensive meadows in the wild where radiation levels remain deadly dangerous. Over time, it leaches back into decontaminated areas.

And as significantly, if not more so, what happens to the out-of-control radioactive blobs of corium? Nobody knows where those are, or what to do about it. It’s kinda like the mystery surrounding black holes in outer space, but nobody dares go there.

Fukushima is a story for the ages because radiation doesn’t quit. Still, the Olympics must go on, but where? ”
