Published July 12, 2012

We made I-131 activity measurements in the thyroid for examinees from two different areas. Seventeen were residents in Tsushima District of Namie Town, heavily contaminated with radioactive materials released from the crippled plant. Forty five were those evacuated from coastal areas including Minami-soma City located to the north of Fukushima Dai-ichi Nuclear Power Plant. We measured activity in the thyroid during the period from April 12th to 16th, 2011…

The maximum I-131 activity detected in the thyroid of an adult was 1.5 kBq. Assuming the inhalation exposure took place for 4 hours on the afternoon of March 15th (see above), we estimated that this person could inhale as much as 85 kBq of I-131. Using the thyroid activity and breathing rate, the maximum atmospheric I-131 concentration was estimated to be 23 kBq m. In our data analysis, we did not consider I-132 exposure due to lack of information.

    No way to know. It's all guesswork. One hot particle can find you, where ever you are.

    so in the first three months the cumulative dose was actually 393 milisievert when taking iodine 132 into account and the iodine 132 is 9 times more effective at damaging the thyroid…

    heres some lies from nature magazine

    Thyroid doses for evacuees from the Fukushima nuclear accident

    Received 19 June 2012 Accepted 28 June 2012 Published 12 July 2012

    ".. Here we report for the first time extensive measurements of the exposure to I-131 revealing I-131 activity in the thyroid of 46 out of the 62 residents and evacuees measured. The median thyroid equivalent dose was estimated to be 4.2 mSv and 3.5 mSv for children and adults, respectively, much smaller than the mean thyroid dose in the Chernobyl accident (490 mSv in evacuees). Maximum thyroid doses for children and adults were 23 mSv and 33 mSv, respectively…"

    490mSv evacuation for belarus etc

    393 mSv NO evacuation for the citizens of fukushima and their CHILDREN!!

    NATURE MAG IS RUBBISH….. UNSUBSCRIBE NOW!!

    Japanese Government criminal nuke apologists have sold out the public once again by making certain that no biopsies are performed on Fukuized children with enlarged thyroids. Next, the so-called medical establishment will not be testing thyroid cancers for their radiation load even after thyroid cancers actually kill these children. So the ONLY information available is from academic and government scientists/shills/sellouts and is based on lowball "estimated thyroid equivalent dose" based on "assumed atmospheric I-131 concentration", blah, blah, blah. No real data to base their study on, because TEP.gov has made certain that no data is available. No data for I-132 (though I-132 dose was 10X higher than I-131). Based on 4 hours (when these people have been experiencing Fukuiodine for more than 16 months.)

    Now, the academics who did this study may mean well. And if they mean well, I believe they could be doing a much better job if they started to collect some actual data on which to base their studies, instead of using estimates and assumptions. Or they might be a part of the paid coverup, with funding from government or nuke industry. If you still live in Japan, begin collecting obits, monitor radiation daily. When people in your neighborhood or town die, record what they died from. Go to the funeral service and ask the family. Document your illness and death. All you will get from Government and Academia is criminal coverup lowball lies.

    That is your sources, how much they are reliable?
    Maybe your source is rubbish? How you have determine, that Nature, which is one of the most respected journal, is rubbish.
    That is your credentials?
