32,000 Workers At Fukushima No. 1 Got High Radiation Dose, Tepco Data Show (japantimes.co.jp)

mdsolar writes: A total of 32,760 workers at the Fukushima No. 1 nuclear plant had an annual radiation dose exceeding 5 millisieverts as of the end of January, according to an analysis of Tokyo Electric Power Co. data. A reading of 5 millisieverts is one of the thresholds of whether nuclear plant workers suffering from leukemia can be eligible for compensation benefits for work-related injuries and illnesses. Of those workers, 174 had a cumulative radiation dose of more than 100 millisieverts, a level considered to raise the risk of dying after developing cancer by 0.5 percent. Most of the exposure appears to have stemmed from work just after the start of the crisis on March 11, 2011. The highest reading was 678.8 millisieverts.

    Employees who work at a nuclear reactor during and immediately after a meltdown should get their healthcare and compensation for life, no questions asked We are asking them to stay and potentially risk horrifying deaths in order to give the public surrounding them time to evacuate; it is a heroic sacrifice for the good of the community and should be built into the cost and risk model of power companies installing nuclear plants.

    The firehose voting is not enough. There are too few people voting on firehose article, making it more open to abuse by those with multiple sockpuppet accounts. There should be a way to downvote articles on the front page, and a karma-like score pre-applied to those people's firehose submissions.

    Why this submissions is flamebait anti-nuclear energy FUD:
    - 5 mSv is background radiation and is a ridiculously low threshold
    - 50 mSv is the standard in places like the US
    - of those 174 workers exposed to the highest radiation dose, we can expect that one will get cancer -- pretty damn good for what's supposed to be one of the worst nuclear disasters!
    - in comparison, how many people got killed by the total lifetime (production to decommission) per energy generated by mdsolar's preferred methods? here's where nuclear stands in comparison: http://nextbigfuture.com/2011/...
    Of course, those that have been here for a while already knew this submission was going to be utter bullshit the moment we saw who posted it.

  5. Radiation Exposure Models are WRONG by SummitCO · · Score: 5, Interesting

    There sure are some scary comparisons of doses and suggestions of risk without any references in the TFA.

    The problem with many exposure limits and risk estimates is that they are all based on the worst case scenario, ultraconservative exposure model: linear no-threshold (LNT). Basically, this model we created in the 1940s assumes that all radiation is bad and more is worse in with a linear dose to risk relationship.

    However, there is not much evidence to support this simplistic model, which is what NRC uses to establish dose limits! We've known it is wrong for a long time. There is evidence that other models, specifically radiation hormesis, are correct. We won't change anything policywise because imagine the gnashing of teeth from the Greens when the newspaper article reads "Government loosens radiation rules! FEAR!"

    But radiation hormesis is supported by the evidence. It suggests that below a certain level, radiation stimulates cellular and DNA repair mechanisms so that there is an opitmal dose of radiation that is ABOVE zero and that only when you go high on a dose in a given time (threshold) does the damage outweigh the stimulated benefits, but the response may be nonlinear for dose vs risk after the threshold.

    Here are just two of the more recent articles on the subject (research goes back a LONG time)

    Other fun pieces of information:
    A chest X-ray is ~1.5mSv.
    An abdominal Cat Scan (CT) is usually 10-20mSv per study.
    Natural radiation exposure for Denver, CO (5280ft): 12mSv per year.

  6. SOLAR KILLS PEOPLE by roman_mir · · Score: 5, Funny

    So in a disaster area a nuclear power plant can cause some radiation leakage and it affects the people who work there. Ok.

    Under normal operating conditions the Sun causes cancer and kills people with Renewable Solar Radiation!!!!!

    Headline: SUN CAUSES CANCER AND KILLS MILLIONS OF PEOPLE!!!

    From WHO:

    Currently, between 2 and 3 million non-melanoma skin cancers and 132,000 melanoma skin cancers occur globally each year. One in every three cancers diagnosed is a skin cancer and, according to Skin Cancer Foundation Statistics, one in every five Americans will develop skin cancer in their lifetime.

    In 2012 alone 232,000 people had new incidents of melanoma, and 55,000 people died from it.

    The SUN is MURDERING people! We need to find safer methods to produce energy, I suggest nuclear.
