we need to put the counter as low as possible if we try to check accurate radiation level.

“It’s 9.99uSv/h when we put a geiger counter directly on the ground.but it gets low when we have it at 1m high from the ground.It means,we need to put the counter as low as possible if we try to check accurate radiation level.(Tohoku university)”

東北大でセシウム137を計測した際に、直置きで9.99μSv/hを軽く振切った線源が、1m離すと何もないかのような値にまで下がった。これはつまり低汚染地域で地上1mの空間線量のみを計測することの無意味さを示すものだと思う。本気で汚染度を計測する気があるのなら直置き以外ないだろう。

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.
