  • Fukushima: Cleaning Up the Mess



    FUTABA, Japan — Futaba is a modern-day ghost town — not a boomtown gone bust, not even entirely a victim of the devastating earthquake and tsunami that leveled other parts of Japan’s northeast coast.

    Its traditional wooden homes have begun to sag and collapse since they were abandoned in March by residents fleeing the nuclear plant on the edge of town that began spiraling toward disaster. Roofs possibly damaged by the earth’s shaking have let rain seep in, starting the rot that is eating at the houses from the inside.
    The roadway arch at the entrance to the empty town almost seems a taunt. It reads:

    Nuclear energy: a correct understanding brings a prosperous lifestyle.”

    Those who fled Futaba are among the nearly 90,000 people evacuated from a 12-mile zone around the Fukushima Daiichi plant and another area to the northwest contaminated when a plume from the plant scattered radioactive cesium and iodine.

    Now, Japan is drawing up plans for a cleanup that is both monumental and unprecedented, in the hopes that those displaced can go home.

    The debate over whether to repopulate the area, if trial cleanups prove effective, has become a proxy for a larger battle over the future of Japan. Supporters see rehabilitating the area as a chance to showcase the country’s formidable determination and superior technical skills — proof that Japan is still a great power.
    For them, the cleanup is a perfect metaphor for Japan’s rebirth.

    Critics counter that the effort to clean Fukushima Prefecture could end up as perhaps the biggest of Japan’s white-elephant public works projects — and yet another example of post-disaster Japan reverting to the wasteful ways that have crippled economic growth for two decades.

    So far, the government is following a pattern set since the nuclear accident, dismissing dangers, often prematurely, and laboring to minimize the scope of the catastrophe. Already, the trial cleanups have stalled: the government failed to anticipate communities’ reluctance to store tons of soil to be scraped from contaminated yards and fields.

    And a radiation specialist who tested the results of an extensive local cleanup in a nearby city found that exposure levels remained above international safety standards for long-term habitation.

    Even a vocal supporter of repatriation suggests that the government has not yet leveled with its people about the seriousness of their predicament.

    “I believe it is possible to save Fukushima,” said the supporter, Tatsuhiko Kodama, director of the Radioisotope Center at the University of Tokyo. “But many evacuated residents must accept that it won’t happen in their lifetimes.”

    To judge the huge scale of what Japan is contemplating, consider that experts say residents can return home safely only after thousands of buildings are scrubbed of radioactive particles and much of the topsoil from an area the size of Connecticut is replaced.

    Even forested mountains will probably need to be decontaminated, which might necessitate clear-cutting and literally scraping them clean.

    The Soviet Union did not attempt such a cleanup after the Chernobyl accident of 1986, the only nuclear disaster larger than that at Fukushima Daiichi. The government instead relocated about 300,000 people, abandoning vast tracts of farmland.

    Many Japanese officials believe that they do not have that luxury; the evacuation zone covers more than 3 percent of the landmass of this densely populated nation.

    Quiet resistance has begun to grow, both among those who were displaced and those who fear the country will need to sacrifice too much without guarantees that a multibillion-dollar cleanup will provide enough protection.

    Soothing pronouncements by local governments and academics about the eventual ability to live safely near the ruined plant can seem to be based on little more than hope.

    Inside the 12-mile ring, which includes Futaba, the Environmental Ministry has pledged to reduce radiation levels by half within two years — a relatively easy goal because short-lived isotopes will deteriorate. The bigger question is how long it will take to reach the ultimate goal of bringing levels down to about 1 millisievert per year, the annual limit for the general public from artificial sources of radiation that is recommended by the International Commission on Radiological Protection. That is a much more daunting task given that it will require removing cesium 137, an isotope that will remain radioactive for decades.

    Trial cleanups have been delayed for months by the search for a storage site for enough contaminated dirt to fill 33 domed football stadiums. Even evacuated communities have refused to accept it.

    And Tomoya Yamauchi, the radiation expert from Kobe University who performed tests in Fukushima City after extensive remediation efforts, found that radiation levels inside homes had dropped by only about 25 percent. That left parts of the city with levels of radiation four times higher than the recommended maximum exposure.

    “We can only conclude that these efforts have so far been a failure,” he said.

    The city has cleaned dozens of schools, parks and sports facilities in hopes of enticing back the 30,000 of its 70,000 residents who have yet to return since the accident. On a recent morning, a small army of bulldozers and dump trucks were resurfacing a high school soccer field and baseball diamond with a layer of reddish brown dirt. Workers buried the old topsoil in a deep hole in a corner of the soccer field. The crew’s overseer, Masahiro Sakura, said readings at the field had dropped substantially, but he remains anxious because many parts of the city were not expected to be decontaminated for at least two years.

    These days, he lets his three young daughters outdoors only to go to school and play in a resurfaced park. “Is it realistic to live like this?” he asked.

    The challenges are sure to be more intense inside the 12-mile zone, where radiation levels in some places have reached nearly 510 millisieverts a year, 25 times above the cutoff for evacuation.

    Already, the proposed repatriation has opened rifts among those who have been displaced. The 11,500 displaced residents of Okuma — many of whom now live in rows of prefabricated homes 60 miles inland — are enduring just such a divide.

    The mayor, Mr. Watanabe, has directed the town to draw up its own plan to return to its original location within three to five years by building a new town on farmland in Okuma’s less contaminated western edge.

    Although Mr. Watanabe won a recent election, his challenger found significant support among residents with small children for his plan to relocate to a different part of Japan. Mitsue Ikeda, one supporter, said she would never go home, especially after a medical exam showed that her 8-year-old son, Yuma, had ingested cesium.
    “It’s too dangerous,” Ms. Ikeda, 47, said. “How are we supposed to live, by wearing face masks all the time?”

    She, like many other evacuees, berated the government, saying it was fixated on cleaning up to avoid paying compensation.

    Many older residents, by contrast, said they should be allowed to return.

    “Smoking cigarettes is more dangerous than radiation,” said Eiichi Tsukamoto, 70, who worked at the Daiichi plant for 40 years as a repairman. “We can make Okuma a model to the world of how to restore a community after a nuclear accident.”

    But even Mr. Kodama, the radiation expert who supports a government cleanup, said such a victory would be hollow, and short-lived if young people did not return. He suggested that the government start rebuilding communities by rebuilding trust eroded over months of official evasion.

    “Saving Fukushima requires not just money and effort, but also faith,” he said. “There is no point if only older people go back.”

    Where They Have Gone

    Japanese Tests Find Radiation in Infant Food

    By HIROKO TABUCHI

    TOKYO — Traces of radioactive cesium thought to be from the crippled Fukushima Daiichi nuclear power plant were detected in Japanese baby formula on Tuesday as concerns about food safety continue almost nine months after the accident.

    Meiji, the Tokyo company that makes the powdered formula, announced the recall of 400,000 cans of it as a precaution, but said the levels of cesium detected were well below the government’s safety limits. Tests found a combined 30.8 becquerels per kilogram of cesium 134 and cesium 137, the company said, compared with the government limit of 200, the company said. (A becquerel is a frequently used measurement of radiation.)

    Babies could still “drink the formula every day without any effect on their health,” Meiji said in a statement.

    Infants and young children are thought to be especially vulnerable to radiation exposure, which can increase risks of cancer and other illnesses.

    A Meiji spokesman said airborne cesium particles might have entered the formula at a factory in Saitama, north of Tokyo. He said the company had been diligent in checking radiation levels in the water, but had not taken enough care to filter for airborne radioactivity.

    Eriko Matsuda, an official at the government-affiliated National Institute of Health Sciences, told the public broadcaster NHK that there was no need for panic because formula is diluted before being fed to babies.

      Re: Fukushima: Cleaning Up the Mess

      From The Journal of Health Physics, January 2002, Vol.82, Number 1, pages 87-93, reference especially to Table 1, the article about Ramsar, Iran by Prof. Mortazavi: The world average annual background dose of radiation is 0.50 mGy/year. But at Ramsar, Iran, because of the hot springs there and the Radium-226 and its daughter products released from the hot springs, the annual dose of radiation from the Earth is 260 mGy/year.

      Now, being an official moron with papers to prove it from Victoria General Hospital in Victoria, BC, I do the division: 260/0.50 of these gobbly-gook units, and I come up with the fact that Ramsar, Iran has 520 times (520x) the world's average background dose of radiation from the Earth.

      Now, why should I be worried about Fukushima which apparently has 25 times (25x) the acceptable standard of background radiation for Japan? I mean, I would think that Fukushima could have 520x the average background radiation for Japan, and there still would be no cause for concern.

      If I might really irritate you (and the EPA in Washington, DC), manazonite sand beaches on Earth have been measured to have 789 mGy/year radiation near Ramsar, Iran. So that would imply that those beaches have: [(789 mGy/year)/(260 mGy/year)]

      = [3.03 times the background radiation at Ramsar, Iran].

      Now being an official moron, I would think that since Ramsar has 520x the world average for annual dose from terrestrial radiation, that manazonite sand beaches nearby Ramsar would have 1,576x the world average for annual dose from terrestrial radiation. And no ill-effects were observed in anyone in or near Ramsar, Iran.

      The bottom-line is that the human-body and all living-things on this planet naturally repair all radiation damage from natural sources. Otherwise, life on this planet would have gone extinct hundreds of millions of years ago.

      Now, let me understand this: You and maybe your friends in the EPA ( and a similar body in Japan ) are concerned about 25x the world average for annual dose from terrestrial sources of radiation at Fukushima, and yet you ignore that Ramsar, Iran has 520x the world average all through its entire town. You guys further ignore that manazonite sands near Ramsar have 1,576x the world average for annual dosage from terrestrial sources of radiation. No ill-health effects were observed: no one-eyed monsters, no tumors, no unusual cancers, no elevated death rates, no mutations, etc.

      Therefore, may I suggest that you not move to Ramsar, and especially do not build a house on the sands nearby. Also, since you are very worried about radiation, do not visit your local hospital. Do not eat bananas. Do not eat bone marrow, nor fish bones. Do not build your house on granite, nor near geysers or hot springs, nor near volcanoes, nor on sand and gravel. Also, do not live in high-altitude cities like Colorado Springs, Colorado nor South Lake Tahoe, Cal./Nev, nor Mexico City, D.F, Quito, Ecuador, Bogota, Columbia, etc. Do not fly in jet aircraft. Do not live ( nor even travel ) near the North or South magnetic poles of the Earth. Stay indoors during magnetic storms. Do not sleep in your basement because the cement is radioactive too. Don't get near coal-fired power plants because the coal dust and smoke releases radionuclides. Don't sleep next to your spouse or pet because their bodies are slightly radioactive..... And definitely, stay out of sunlight!

      But what do I know?

        from what eye have been able to see, mr steve, just enuf to be dangerous...

        to the status quo on nuke power and the failure of US energy policy/politix to account for the fact that we have/have had for decades the solution to ALL our problems with regard to peak oil, global warming/climate change, air polution, endless war over oil in the middle east, endless budget deficits to pay for all the above and an immediate cure for the 20-25% unemployment that all of the above has generated, directly or indirectly (considering that 4bux/gal gasoline popped the RE bubble in 2008)

        but we dont wanna even talk about it because.... ?

        yep - dangerous, mr steve
