7.92 mSv/y of external exposure in Koriyama Fukushima based on the data of November

From the data taken in November, it is assumed that a child (under 6) in Koriyama Fukushima may be externally exposed to 7.92 mSv/y. Koriyama Fukushima announced this result on 1/6/2012.

Koriyama Fukushima distributed 16,400 of dosemeters to children under 6 and people who hoped to have one, and collected the data of accumulated dose of November from 15,239 of children and 896 of pregnant women.
As a result, the average external dose of children was 0.11 mSv/m, and the one of pregnant women was 0.10 mSv/m. The highest reading of pregnant women was 0.36 mSv/m.
If it was based on the data of March or April, the result would have been much higher.

読売新聞 1月6日(金)22時53分配信
福島県郡山市は6日、市内の未就学児と妊婦の昨年11月の1か月間の個人積算線量の測定値で、未就学児1人から0・66ミリ・シーベルト、年間換算では7・92ミリ・シーベルトと比較的高い線量が測定されたと発表した。

市では「今のところ健康に影響を与える数値ではないが、今後も調査を継続して対応していきたい」としている。

平均値は未就学児が0・11ミリ・シーベルト、妊婦が0・10ミリ・シーベルトで、妊婦の最高値は0・36ミリ・シーベルトだった。

市は昨年10月末から、保育園や幼稚園、希望者を対象に約1万6400個の線量計を配布。同11月の積算の放射線量を測定してもらい、妊婦896人と未就学児1万5239人から回収した。

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
