    Close to 40% for TESTED children have cysts. In most medical discussions, children having cysts is rare, except of course, in Fukushima or Chernobyl. All cysts should be tested for cancer! So if I was a parent, and the testing was NOT done on my child, I would be very very worried. And if tested, and found with a cyst–its not a "watch do nothing" activity. For those found clear,at this time, testing is necessary at least yearly.

      japan needs socialised care .. now!! like in europe because the children will be moving around as will the adults.. its fair for all too! cost effective and necessary imo..

      .. the children of fukushima need to be in less contaminated areas.. japan needs to import food for the people and step up monitoring of soils, water and food…..

      its gotta be done..

    Thyroid doses for evacuees from the Fukushima nuclear accident

    Shinji Tokonami, Masahiro Hosoda, Suminori Akiba, Atsuyuki Sorimachi, Ikuo Kashiwakura & Mikhail Balonov

    "…A primary health concern among residents and evacuees in affected areas immediately after a nuclear accident is the internal exposure of the thyroid to radioiodine, particularly I-131, and subsequent thyroid cancer risk. In Japan, the natural disasters of the earthquake and tsunami in March 2011 destroyed an important function of the Fukushima Daiichi Nuclear Power Plant (F1-NPP) and a large amount of radioactive material was released to the environment. 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….."

      Fukushima prefecture stopped Hirosaki University's investigation at the time, so this study is not a complete picture. In news report dated 3/9/2012, they reported maximum of 87 mSv for adults and 47 mSv in children.
      http://www.asahi.com/national/update/0309/TKY201203090004.html

      In the article they assume only 4 hours of inhalation in the afternoon of 3/15/2012 because rain beginning at 5 pm made radioactive materials fall on ground, making them unavailable for inhalation. They also assume ingestion negligible due to stopped milk consumption.

      On Table 2 they estimated thyroid dose for children using assumed maximum atmospheric I-131 concentration, showing 36-63 mSv.

      Incidentally, one of the co-authors wrote this.

    • Thank you both Arclight and FRCSR for these links.

      here is the info I've collected so far. I'll add yours:

      On July 6 2011 the Japanese press Kyodo reported that in a March survey of 1,080 children aged 0 to 15 in Iwaki, Kawamata, and Iitate, 45% of kids in Fukushima survey had thyroid exposure to radiation

      In August 2011, NHK reported that Japan’s nuclear commission had erased children’s exposure data derived from a test of 1,000 children aged 15 or younger who had been screened for radiation affecting their thyroid. The report stated that one four year old child had a thyroid exposure of 35 millisieverts, but that the amount was “not considered a health threat.”

      This exposure level accounts only for Iodine-131 and does not incorporate the child’s total exposure to other radionuclides.

      In April 2012, the Peace Philosophy Centre posted the results of the Fukushima government’s March 2012 survey of 38,001 children under 18 located in thirteen Fukushima prefecture cities. Thyroid nodules (5.0mm) or cyst (20.0mm) were detected in 13,460 individuals, or 35.3% of the sample. These results were an increase of 5.6% from a January pre-test.

    • I don't know anything about measuring iodine-131 in thyroids.

      Does anyone have the expertise to comment on the methodology employed in the article published at Nature, cited by Arclight here:

      valuation of thyroid equivalent dose
      http://www.nature.com/srep/2012/120712/srep00507/full/srep00507.html

      "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, using a 3-inch × 3-inch NaI(Tl) scintillation spectrometer (JSM-112, Hitachi Aloka Medical, Ltd., Tokyo). We wrapped the detection head with plastic foil and cleaned the neck with alcohol wipes so as to avoid radioactive contamination. We then placed the detection head on the cleaned part of the neck and started the measurement. After 300 sec, we obtained a gamma-ray pulse height spectrum. Using the I-131 counting data, we calculated the activity by the equation (1):

      • Retrospective thyroid equivalent dose by inhalation for young children

        In order to estimate the retrospective thyroid dose by inhalation for young children with high risk, we used the maximum atmospheric I-131 concentration estimated from the thyroid activity of evacuees. We calculated the concentration (CI: Bq m−3) as the following equation:

        MAJIA HERE It seems there is a an awful lot of speculation and guessing going on in this article but I lack the expertise to evaluate it…

      They are not trimming employees, just reducing the cost of those they have. They will be replaced by younger, less expensive employees. So, the appearance is given to the public that they are cutting costs, but as time goes by, the cost will be the same.

      Also, I question whether the new hires will be even as "liberal" as the previous employees. It's now a different NRC.

    READ this article that follows for treatment guildlines! Normally doctors find 1.5% children with thyroid noduals/cysts. Fukushima…35.8% of children have noduals/cycts. HUGE HUGE increase–23 times!. And that in less than a YEAR of exposure. If someone can translate and post the article, it would help in the decision for care:

    All they worry about is Iodine 131, just like worry about number 4 and forget about the others. I'm certain the thyroid is not all being effected by radiation. Just one radioactive isotope? Come on.

    Let us be kind, one to another, for we are each of us together in our radiation exposure.

      We know radioactive iodine concentrates in thyroid but so does cesium:
      Yury Bandazhevsky was the first to create an institute in Belarus, in 1989, specially dedicated to scientific work on the 1986 Chernobyl disaster. Caesium-137 levels in children's organs were examined at autopsy. The highest accumulation of Cs-137 was found in the endocrine glands, in particular the thyroid, the adrenals and the pancreas. High levels were also found in the heart, the thymus and the spleen." (Wikipedia bandazhevsky)
      ALso yttrium 90, daughter product of strontium 90 affects endocrine organs:
      "Yttrium-90 doesn't mimic calcium, like strontium 90. But, like Sr90, it is also an organ-seeker and spews out a beta ray (and a gamma too). Whereas strontium-90 seeks out the skeleton, Yttrium-90 seeks out many soft tissue organs of the body, including the reproductive organs, the liver, lung, pancreas, and also the thyroid and pituitary glands. Many of these soft tissue organs have glandular functions that play important roles in adult life and in child-bearing. When the thyroid-pituitary is damaged by radiation in pregnant mothers, hormone level imbalances can create a hostile environment for prenatal development, especially for the radiosensitive brain organ and the lungs…Although yttrium-90 has a half-life of just 64 hours – it decays to safe levels in about 30 days – there is a constant supply of fresh Yttrium-90 from the decay of strontium-90 in our bones." con't

        "Although yttrium-90 has a half-life of just 64 hours – it decays to safe levels in about 30 days – there is a constant supply of fresh Yttrium-90 from the decay of strontium-90 in our bones. It emerges from the bone marrow into the blood and collects in the soft tissue organs. Our bodies are thus radiochemical factories: 24 hours a day, and 7 days a week, strontium-90 from our hard organs – the bone and teeth – is processed into yttrium-90 that collects in the soft tissues. Yttrium-90 emits a beta and gamma ray to become stable and non-radioactive zirconium-90, which is no good for our bodies either!" http://www.nuclearcrimes.org/3-4.php
        So there are other avenues to assault the endocrine glands with man-made radionuclides besides I-131.

    There are over 310,000 more Fukushima children still awaiting thyroid examination.

    Please refer to this article about the January letter from Shunichi Yamashita to members of Japan Thyroid Association, asking them to adhere to the guidelines set by Fukushima University Medical School.

    http://fukushimavoice-eng.blogspot.com/2012/05/fukushima-childrens-thyroid-examination.html

    "Although Fukushima University Medical School claims that these ultrasound findings are “mostly normal” and commonly found in children, the study co-authored by Shunichi Yamashita in 2001 revealed that normal children in Nagasaki had 0% nodules and 0.8% cysts on ultrasound."

    A team of researchers led by Toshikazu Suzuki, a section head at the NIRS Research Center for Radiation Emergency Medicine, conducted an independent study of the same measurement data. The team estimated the lifetime thyroid doses of the 1,080 children at 12 millisieverts on average and 42 millisieverts at the maximum. The dose estimates were 30 millisieverts or more for four of the subjects. The children tested were from at least 10 municipalities, and the dose estimates tended to be higher for those from Iitate and Iwaki.”

    The NIRS study also found many of the children with “zero” according to the government actually had a lifetime equivalent dose. “Despite the government announcing more than half of the children had zero exposure, the independent study found that on average they did receive thyroid gland doses of internal radiation. Several children were judged to have received an equivalent lifetime dose to the thyroid.”

    "Fukushima Medical University, as you recall, has Dr. Shunichi Yamashita as the vice president. He and his associates are responsible for telling the residents in Iitate-mura and other high radiation cities and towns in Fukushima that it was safe to be outside, to eat vegetables, to drink water, when the radioactive fallout was falling heavily in Fukushima in March and April."

    Doctor, how can he be a doctor with that kind of advice. Maybe he has a background or family as coroners. He needs to be force fed fuku produce. Remember the need to share and smile. For his misleading lies, drinking cooling water ought to do the trick.

    What are children still doing in Fukushima, Japan?? NO child should be hanging around a nuclear accident or explosion, much less three uncontained meltdowns!!!….but some are STILL there???

    I'm very sorry to read about these kids. The requisite expectation of a "normal life" for your children may be subject to change soon!!…For millions!…

      Fukushima prefecture is doing everything possible to keep children there, going so far as offering free medical care for all children. It's critical for Fukushima to be carrying on "normal" life so that the nuclear industry can go on with their plans.

      “Without recovery of Fukushima, there is no future for nuclear power in Japan” – this is the commitment of the nuclear industry. We will devote ourselves entirely to restoration of municipalities around the station and to decommissioning the reactors."

      http://www.par-anoia.net/innodata/fd/Takashi_Imai_As_March_11_nears.pdf

      This is part of the Fukushima Prefecture Health Management Survey" which shows the external exposure dose.

      "The Committee assessed the results saying 'these estimates
      lead us to believe there will be no effect on the health of the residents surveyed' based upon previous epidemiological studies."

      http://daniel.domos.jp/wp-content/uploads/2012/07/F-Rad-Health-Survey-61212-Final-PDF.pdf

      Cover-up, lies, and minimization have always been three pillars of the nuclear industry's strategy.

    Officials never talk about that because the one that runs a nuclear plant has to pay the iodine prophylaxis and hiding the fact that adults are at risk too cuts in half the costs.
