2 Sv/h from leaked water

2 Sv/h from leaked water

Following up this article ..Water leaks at 3 more locations
Contaminated water keeps leaking in Fukushima.

On 2/3/2012, Tepco found water leaking from the tank of contaminated water. Though it was less than 1L, they measured 2 Sv/h of Beta ray on the surface. They also measured 22mSv/h of Gamma ray from its surface too.
It was stopped only to fasten the bolt but it contains a lot of strontium, they measured 15mSv/h of Beta ray even though they put acrylic shield. (1mSv/h of Gamma after shield)

水漏れた付近でベータ線2000ミリシーベルト 福島第1原発

東京電力は3日、福島第1原子力発電所の汚染水貯蔵タンクから水漏れし、毎時2千ミリシーベルトの高いベータ線を検出したと発表した。微量で水たまりはできておらず、海への流出もないという。ボルトを増し締めし、漏水は止まった。アクリル板などで遮蔽し、ベータ線は毎時15ミリシーベルトまで下がった。

淡水化装置で濃縮した汚染水の貯蔵タンクの継ぎ手部分の締め付けが緩み、漏水したとみている。水にはストロンチウムが多く含まれるという。直下のコンクリート周辺で、ベータ線のほかにガンマ線も毎時22ミリシーベルトを検出した。遮蔽によって1ミリシーベルトに低下した。

経済産業省原子力安全・保安院は3日、水漏れが相次ぎ見つかっていることを重視し、原因究明と再発防止策を報告するよう東電に指示した。

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.
