Media, Academia Join Forces to Downplay Dangers of Nuclear Power | Dissident Voice - 0 views

    "Last April 20 the New England Journal of Medicine (NEJM) published an on-line article entitled "Short-term and Long-term Health Risks of Nuclear-Power-Plant Accidents" by Dr. Eli Glatstein and five other authors. The article was riddled with distortions and misinformation, and overall was very poor research. As the NEJM is a peer reviewed journal and has a significant letters section, I wrote a letter pointing out some of the errors committed by the authors, and a longer piece containing a comprehensive critique.

    The NEJM demands that letters to the journal contain material that has not been submitted or published elsewhere, so I had to refrain from submitting my longer piece anywhere until the NEMJ made a decision on my letter. When my letter did not appear after a couple of weeks I inquired, and was told that the article would soon appear in the printed version of the Journal, and that no letters about the article could be published until after the print version came out. The printed version finally appeared on June 16."

Fukushima shiitake cesium spikes | The Japan Times Online - 0 views

    "Fukushima shiitake cesium spikes

    FUKUSHIMA - Radioactive cesium exceeding the designated limit has been detected in shiitake grown in greenhouses at a farm in Soma, Fukushima Prefecture, the prefectural government said.

    The prefecture said Saturday it has asked the city of Soma and dealers to stop shipment of the mushrooms, and a local agricultural cooperative has begun recalling them after they were found to contain 850 becquerels of cesium per kilogram, exceeding the 500-becquerel limit set by the state.

    The farm in question has grown the mushrooms on beds made of a mixture of wood chips and nutrients, and the wood chips used in them are suspected to have been contaminated with the radioactive substance, according to the local government. The mushroom beds were sold by the Soma agricultural cooperative.

    The farm has shipped 1,070 100-gram packages of shiitake since Oct. 24, and they are believed to have been sold at nine supermarkets in the prefecture from Tuesday. No other shiitake produced by the farm have entered the market, it said."

Fallout forensics hike radiation toll : Nature News - 0 views

  • The new study challenges those numbers. On the basis of its reconstructions, the team claims that the accident released around 1.7 × 1019 Bq of xenon-133, greater than the estimated total radioactive release of 1.4 × 1019 Bq from Chernobyl.
    "The disaster at the Fukushima Daiichi nuclear plant in March released far more radiation than the Japanese government has claimed. So concludes a study1 that combines radioactivity data from across the globe to estimate the scale and fate of emissions from the shattered plant.

    The study also suggests that, contrary to government claims, pools used to store spent nuclear fuel played a significant part in the release of the long-lived environmental contaminant caesium-137, which could have been prevented by prompt action. The analysis has been posted online for open peer review by the journal Atmospheric Chemistry and Physics. "

Fukushima victims are desperate, angry - World news - Asia-Pacific - - 0 views

  • After claimants have read a 160-page instruction manual, they then have to fill in a 60-page form and attach receipts for lodging, transportation and medical costs.
  • A government panel overseeing the compensation scheme estimates claims are likely to reach 3.6 trillion yen ($46.5 billion) in the financial year to next March.
  • An Asahi newspaper poll showed this month that 43 percent of evacuees still want to return, down from 62 percent in June.
    "At last, victims of Japan's nuclear crisis can claim compensation. And they are angry.

    They are furious at the red tape they have to wade through just to receive basic help and in despair they still cannot get on with their lives seven months after the huge quake and tsunami triggered the world's worst nuclear disaster in 25 years.

    Shouts fill a room at a temporary housing complex where seven officials, kneeling in their dark suits, face 70 or so tenants who were forced to abandon their homes near the Fukushima nuclear plant after some of its reactors went into meltdown after the March 11 quake struck."

Journalists keep close eye on Fukushima nuclear worker radiation exposure (Part 3) - Th... - 0 views

  • A 30-year-old worker for a sub-subcontractor said he had been told by an employee of the subcontractor, "We won't write down the amount of radiation you were exposed to during the latest work on your radiation management record. You don't have to worry about it."
    "Health ministry regulations stipulate that nuclear power station workers can be exposed to a maximum of 100 millisieverts over five years, and 50 millisieverts in a single year. However, in the case of an emergency such as a nuclear accident, they can be exposed to up to 100 millisieverts during work to bring the plant under control. In the Fukushima nuclear crisis, the ministry raised the upper limit to 250 millisieverts.

    The ministry concluded that workers who are exposed to 100 to 250 millisieverts during efforts to tame the Fukushima nuclear crisis must be withdrawn from further work for five years on the grounds that the conventional regulations apply to the Fukushima crisis."

Austrian authorities release detailed data on Japan radiation | Science & Technology | ... - 0 views

    ""The estimated source terms for iodine-131 are very constant, namely 1.3 x 10^17 becquerels per day for the first two days (US station) and 1.2 x 10^17 becquerels per day for the third day (Japan)," the institute said in a German-language statement posted on Wednesday on its website.

    "For cesium-137 measurements, (the US station) measured 5 x 10^15 becquerels, close, while Japan had much more cesium in its air. On this day, we estimate a source term of about 4 x 10^16."

    A "becquerel" is the unit that measures how many radioactive nuclei decay per second, and the "source term" refers to the quantity and type of radioactive material released into an environment.

    "The nuclear catastrophe at Chernobyl had a source term of iodine-131 at 1.76 x 10^18 becquerels of cesium-137 at 8.5 x 10^16 bequerels," the statement added. "The estimated for Fukushima source terms are thus at 20 percent of Chernobyl for iodine, and 20-60 percent of Chernobyl for cesium.""

News: Actual fallout was 10 times more than reported | Fukushima Diary - 0 views


    Ministry of Education, Culture, Sports, Science and Technology admitted that they have made a "mistake" on the report about fall out in Fukushima.

    The data is about the amount of fallout and the rain, from 6/6/2011 ~ 8/4/2011.

    Having said that it was a simple error, it turned out that it was 10 times more than originally reported.

    For example…


    Cs-134 6.6 MBq/km2 → 160 MBq/km2
    Cs-137 8.0 MBq/km2 → 200 MBq/km2


    Cs-134 31 MBq/km2 → 590 MBq/km2
    Cs-137 39 MBq/km2 → 750 MBq/km2"

Gov't panel eyes higher interim radiation exposure limit - The Mainichi Daily News - 0 views

    "A government panel on reviewing radiation dose standards plans to propose that the government adopt an interim annual radiation exposure limit between 1 to 20 millisieverts for ordinary people instead of the current 1 millisievert limit, panel sources said Wednesday.

    The recommendation by a group under the panel, headed by Otsura Niwa, a professor emeritus at Kyoto University, would be employed when the government reviews provisional radiation limits for food products and soil, many of which were hurriedly set after the start of the nuclear crisis at the Fukushima Daiichi power plant.

    However, the plan to raise the annual radiation exposure limit for ordinary people could be criticized for endangering health, potentially affecting the subsequent review process, observers said."

High Levels Of Contamination Found Outside Evacuation Zone | SimplyInfo - 0 views

    "MEXT has released more contamination level data that shows considerably high levels outside the 20km evacuation zone, mostly concentrated in a north west path. As data has been coming out recently the north west path has shown to have taken considerable fallout over the last six months. There were also soil samples taken, these showed levels outside the evacuation zone in 66 locations exceeded the evacuation threshold used in Chernobyl. Okuma is 30km from the plant and showed millions of becquerels on the soil sample tests. Namie and Iitate were showing high levels on the MEXT sampling information, both are outside the evacuation zone.

    Some of this area to the north and west had been evacuated, but there are still people in this northwest stretch that the government has not done anything to help."

Gov't may lift evacuation advisory outside 20-km zone in Sept. - The Mainichi Daily News - 0 views

    "he government is aiming to lift by the end of September its advisory for residents living in areas outside the 20-kilometer zone around the Fukushima Daiichi nuclear plant that have been designated for evacuation in the event of an emergency, Chief Cabinet Secretary Osamu Fujimura said Tuesday.

    The move came after five municipalities in Fukushima Prefecture, all or parts of which are designated as emergency evacuation preparation zones in the 20- to 30-km ring from the power station, had submitted to the central government by Tuesday their "recovery plans," a precondition for lifting the advisory."

    "An extensive area of more than 8,000 square kilometers has accumulated cesium 137 levels of 30,000 becquerels per square meter or more after the accident at the Fukushima No. 1 nuclear power plant, according to Asahi Shimbun estimates.

    The affected area is one-18th of about 145,000 square kilometers contaminated with cesium 137 levels of 37,000 becquerels per square meter or more following the 1986 Chernobyl accident in the former Soviet Union.

    The contaminated area includes about 6,000 square kilometers in Fukushima Prefecture, or nearly half of the prefecture. Fukushima Prefecture, the third largest in Japan, covers 13,782 square kilometers.

    The government has not disclosed the size of the area contaminated with cesium 137 released from the crippled Fukushima No. 1 plant. Cesium 137 has a long half-life of about 30 years.

    The Asahi Shimbun calculated the size of the contaminated area based on a distribution map of accumulated cesium 137 levels measured from aircraft, which was released by the science ministry on Sept. 8. "

Tepco sends applications for crisis damages | The Japan Times Online - 0 views

    "Tokyo Electric Power Co. on Monday started sending out some 60,000 application forms to people seeking damages due to the nuclear crisis at its Fukushima No. 1 power plant.

    The 60,000 forms are being sent to households that have already received provisional compensation. Those who are filing for the first time need to ask Tepco to send an application form.

    Applicants are required to attach necessary documents, such as receipts, to apply for compensation for transportation costs, lodging expenses, mental suffering and other problems. Under the full-scale compensation scheme, an evacuee who has been forced to flee in line with a government order will receive ¥5,000 for moving from one place to another inside Fukushima Prefecture. A person will also be given up to ¥8,000 per night for staying in a hotel."

Radiation expert says outcome of nuke crisis hard to predict, warns of further dangers ... - 0 views

    "As a radiation metrology and nuclear safety expert at Kyoto University's Research Reactor Institute, Hiroaki Koide has been critical of how the government and Tokyo Electric Power Co. (TEPCO) have handled the nuclear disaster at the Fukushima No. 1 nuclear plant. Below, he shares what he thinks may happen in the coming weeks, months and years.

    The nuclear disaster is ongoing. Immediately after the crisis first began to unfold, I thought that we'd see a definitive outcome within a week. However, with radioactive materials yet to be contained, we've remained in the unsettling state of not knowing how things are going to turn out."

Nuclear - a powerful case against (environmentalresearchweb blog) - environmentalresear... - 0 views

    " Sovacool reports that 21 deaths have so far been linked to Fukushima - 7 from first responders and plant operators, and 14 elderly people who died during the evacuation process. None of these were due to radiation exposure, but he notes that 160 people have so far been exposed to 'hazardous' levels of radiation. Hopefully the final outcome will be less than the thousands of early deaths that followed Chernobyl - Sovacool quotes the low IAEA-WHO estimate of 4000, but also points to other studies, which suggest 93,000 early cancer deaths. But away from the media spotlight, there are claimed to be continuing deaths and disease as a result of routine emissions and occasional leaks from nuclear facilities: Sovacool quotes 3,780 premature deaths and 1,253 cancers globally per annum.

    Of course it's not just people that have to be buried, but also nuclear waste. The back end of the nuclear cycle is probably its worst aspect- unless you are concerned about the prospects of terrorist attacks, the illegal diversion of nuclear material, or the proliferation of weapons making capacity. The latter issues relate to current geo-political conflicts, but the waste issue takes us beyond that into the far future. Sovacool quotes Alvin Weinberg's comment that, in terms of guarding and managing nuclear wastes, humanity seemed to have a ' remarkable belief that it can devise social institutions that are stable for periods equivalent to geological ages'."

    "A group of Japanese researchers say that a total of 15,000 terabecquerels of radioactive substances is estimated to have been released from the crippled Fukushima Daiichi nuclear power plant into the sea.

    Researchers at the Japan Atomic Energy Agency, Kyoto University and other institutes made the calculation of radioactivity released from late March through April.

    The combined amount of iodine-131 and cesium-137 is more than triple the figure of 4,720 terabecquerels earlier estimated by Tokyo Electric Power Company, the plant operator. The utility only calculated the radioactivity from substances released from the plant into the sea in April and May.

    The researchers say the estimated amount of radioactivity includes a large amount that was first released into the air but entered the sea after coming down in the rain.

    They say they need to determine the total amount of radioactivity released from the crippled Fukushima Daiichi plant in order to accurately assess the impact of the disaster on the sea."

    The Semipalatinsk region suffered under four decades of Soviet nuclear testing. Now, the country wants to become an international research hub for the effects of radiation on future generations. Matilda Lee reports from Kazakhstan

    Ground zero is an hour and a half drive away from the Kazakh National Nuclear Centre (NNC) along a dusty road in the seemingly endless steppe. The Ecologist is in the Semipalatinsk (renamed Semey in 1991) region of eastern Kazakhstan to observe one of the world's nuclear hotspots: the epicenter of the Soviet Union's previous - and highly controversial - nuclear testing programme.

    The cost of generating nuclear power in Japan is one-third higher than Tokyo's last cost assessment in 2004 and 50 percent higher if compensation costs for the recent nuclear crisis are included, but still cheaper than fossil fuels, a study showed this week.

    The study by the country's top energy research firm could provide fodder for both sides of Japan's nuclear power debate, which is expected to heat up amid public wariness over nuclear safety despite the prospect of protracted power shortages.

    Lawmakers and officials are working to come up with a new energy policy after the Fukushima radiation crisis made it difficult, if not impossible, to build more reactors in the world's third-biggest nuclear generator.

    Prior to the crisis, as part of its effort to fight climate change, Japan planned to boost nuclear capacity to meet over half of electricity demand by 2030 by building 13 more reactors.

asahi: Made-in-Fukushima products still shunned amid radiation fears - English - 0 views

    After struggling for months to repair production lines hammered by the March 11 earthquake and tsunami, a Saitama Prefecture-based maker of plastic containers threw in the towel.

    The damage had been overcome at its plant in Tamura, Fukushima Prefecture, one of the company's main production centers. But it could not cope with consumer fears that its products, including lunch boxes, were contaminated with radiation spewed from the Fukushima No. 1 nuclear power plant.

    "It will be difficult to restart the plant until the nuclear accident comes to an end," said a company official.
