Cesium from Fukushima reached to 5000m deep in the sea in April

11/20/2011, Japan Agency for Marine-Earth Science and Technology announced that in April, Cesium from Fukushima dropped from air to the pacific ocean and fell down deep in the sea attached to dead plankton.

4/18~4/30, Japan Agency for Marine-Earth Science and Technology measured cesium from particles which is made of dead plankton or sand, smaller than 1mm, called “Marine snow”.

It was off shore of Polustrov Kamchatka, where is 2,000 km away from Fukushima and 5,000 meters deep in the sea around Ogasawara islands, where is 1,000 km away from Fukushima.

From the ratio of cesium 134 and 137, they judged it was from Fukushima plants. They have not announced the amount of cesium.


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.
