Prof. Yamauchi Tomoya from Kobe university confessed the board of education of Koriyama city stops decontamination, on the radio show MBS Tanemaki journal. (Assistant professor Koide from Kyoto university regularly talks on this radio show as well.)
It was recorded on 4/30.
He is an expert of decontamination. On the radio show, he talked his experience when he went to a kindergarten and elementary school of Koriyama city to assist decontamination but the board of education stopped him from decontaminating. The reason was not talked.
He also added, the safety limit is 0.23μSv/h. If it goes over 0.23μSv/h, local government must decontaminate the school areas, but actually it was difficult to find somewhere less than 0.23μSv/h though it was after decontamination.
Contaminated soil was already removed and new soil was added, but places surrounding the playground of elementary school or kindergarten are still highly contaminated, radiation comes over the playground. If those severely contaminated areas are not owned by schools, it is impossible to decontaminate it.
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.
