12,100 Bq/Kg from sludge ash

Bureau of sewerage in Tokyo published the measurement data of radiation contained in the incinerated ash of sewage sludge.

It is not the incineration ash of radioactive debris, but just normal sewage sludge.

The samples were taken from 3/6~3/13/2012. As the result, high level of cesium was measured from the incineration ash made at 12 of 12 sewage plants.

The highest reading was 12,100 Bq/Kg (Cesium 134 and 137) measured at Kasai Tokyo.

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.
