Highly contaminated water still keeps leaking to the sea


Mr. Aoyama from Meteorological Research Institute analyzed the decreasing speed of cesium in the ocean. He talks highly contaminated water is probably still leaking to the sea because the decreasing speed of cesium is too slow.
Tepco put water glass medical fluid to stop water leakage last April. They state the cesium level has decreased drastically since last March. The decreasing speed of cesium is slow in these 3 or 4 months, but they don’t think the contaminated water is still leaking.

On 3/6/2012, Yomiuri newspaper reported that Mr. Miyazawa from Japan Agency for Marine-Earth Science and Technology calculated about 5,600 tera Bq of cesium 137 has leaked to the sea, which is 6 times as much as Tepco’s data.
However, it’s only cesium 137, not including cesium 134, and it’s the leaked amount by 5/7/2011.

The entire situation of marine pollution is not known yet.

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.
