Highest level of Cs-134/137 detected in seawater of Fukushima plant port entrance
Although Japanese Prime Minister Abe states contaminated water is blocked, the Cesium-134/137 density marked the highest level in seawater on 10/11/2013.
The location is the port entrance. The reading was exactly 10,000 Bq/m3 (Cs-134 : 2,700 Bq/m3, Cs-137 : 7,300 Bq/m3).
The former highest reading was 6,300 Bq/m3 measured on 8/19/2013.
The cause of increase was not announced but on 10/9/2013, Cs-134/137 density jumped up by 13 times in front of reactor2. It may have affected the radioactive density in port entrance. (cf, Cesium-134/137 density jumped up 13 times much as one day before in Fukushima plant port [URL])
Radioactivité record en césium 134/137 dans l’eau à l’entrée du port de la centrale de Fukushima
En dépit des affirmations de M. Abe, le premier ministre japonais, disant que les eaux extrêmement radioactives sont contenues, ce 11 octobre 2013 la radioactivité en césium 134/137 a marqué un record dans l’eau de mer.

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.
