5 July 2011 The Nuclear Safety Commission headed by Haruki “Detarame” Madarame disclosed on July 4 that the test conducted in late March had found 45% of 1,080 children tested in Fukushima Prefecture had internal radiation exposure at thyroid gland, according to Tokyo Shinbun. 3 months, that seems to be the amount of time that these government people must feel safe to disclose what they had known all along. After 3 months, people may forget, and/or people will give up because the disclosure is too late. The NSC says the levels were low, and there was no need for more detailed evaluation. If you look at the numbers, though, you may wonder how they came to the conclusion. To them, 100 millisieverts per year body dose equivalent for 1 year old (or 0.2 microsievert/hour) was acceptable because the ICRP says so. Since the highest they found was 50 millisieverts per year body dose equivalent, they concluded there was no need for further testing. From Tokyo Shinbun (7/5/2011):

東京電力福島第一原発の事故で、国の原子力安全委員会は四日、三月下旬に福島県内の第一原発周辺の市町村に住 む子供約千人を対象に行った放射線被ばく調査で、45%の子供が甲状腺に被ばくしていたことを明らかにした。安全委の加藤重治審議官は「精密検査の必要は ないレベル」と話している。 Japan’s Nuclear Safety Commission disclosed on July 4 that the survey done in late March on 1,000 children living near Fukushima I Nuclear Power Plant had revealed that 45% of the children were exposed to radiation at the thyroid gland. Commissioner Shigeharu Kato says “The radiation level was not the level that would require more detailed examination.” […]

So the Japanese government was secretly testing the children in Iitate-mura, as it scoffed at the suggestion by IAEA that the radiation level in the village was very high and evacuation should be considered. All back in late March when it could have made a difference. […]
