3 academic societies have started studying about the possible spread of cesium pollen

 

 

Following up this article ..26 microSv/h from the leaves of Japanese cedar

Japan Geoscience Union and other 2 academic societies have started survey to know how cesium spreads with pollen this spring.
Forestry Agency has already asserted the possible exposure of cesium would be only 0.000192 microSv, which is ignorable. This survey of them makes us question why they need to survey it even though it is not risky.

They are going to survey at 11 locations in Fukushima, Miyagi, Ibaraki and Tokyo. They will start publishing the result from the end of January at the earliest.

セシウム:花粉での拡散、調査し公表へ

日本地球惑星科学連合など3学会は、東京電力福島第1原発事故による放射性セシウムがスギ花粉によってどう拡散するかを分析する調査を始めた。観測結果は、早ければ今月末からホームページ上で公開する。

福島、宮城、茨城の各県と東京都の計11カ所で、一定体積の大気中に含まれるスギ花粉の量と、放射性物質濃度を調べる。同時観測することで、スギ花粉による放射性物質飛散量を推定できる。

昨年12月に林野庁が公表した中間報告では、福島県内87カ所で調べたところ、花粉を吸い込むことによる推定被ばくは毎時最大で0.000192マイクロシーベルト程度で、人体が受ける影響は十分に小さいとしていた。

観測チームの北和之・茨城大准教授(大気環境科学)は「森林ではなく実際に人が住んでいる場所に、どの程度花粉が輸送されるかの理解につなげたい」と話している。公開するホームページはhttp://www.jpgu.org/【久野華代】

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.
