70,400 Bq/Kg from ventilation system of incineration plant in Tokyo

High level of cesium was measured from dusts stuck in air filters of the waste incineration plant in Sumida Tokyo.


(Measurement date : 1/18/2012, cesium 134+137)

1. Dusts on deodorising apparatus of activated carbon

Sample 1 ) 61,100Bq/kg   18kg

Sample 2 ) 31,700Bq/kg  26kg


2. Dusts on ventilation facility of ash bunker room

70,400Bq/kg  11kg


Clean Association of TOKYO23 states, it’s not from the incineration ash, it’s from the air outside of the plant.

They assume hot particles in the air were caught by the filters from mid January to mid March of 2011. Currently they are discussing  how to process it with the government.

They keep the dusts on the basement floor until they get to the conclusion.





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.
