According to Gunma prefectural government, 24 Bq/Kg of I-131 was detected from dehydrated sludge of a sewage plant.

From their monthly report published on 8/7/2015, the sample was collected from 7/27 to 7/29/2015. The sewage plant is situated beside Tonegawa River.

33 Bq/Kg of Cs-137 was also detected from the same sample.


I-131 was detected from 2 of 6 samples in June and May as well. The highest reading was 49 Bq/Kg.


From the sample of 6/23 ~ 6/26/2015, Cs-134 was measured to prove the dehydrated sludge is also under the effect of Fukushima accident.

Selon la préfecture de Gunma, 24 Bq/kg d’iode 131 ont été relevés dans des boues séchées d’une station d’épuration.
Dans leur rapport mensuel du 7 août 2015, des échantillons ont été pris entre le 27 et le 29 juillet 2015. La station d’épuration se trouve à côté du fleuve Tonegawa.
On relève également 33 Bq/kg de Cs-137 dans ces mêmes échantillons.

De l’ iode 131 avait également été relevé dans 2 des 6 échantillons de mai et de juin. Le record est de 49 Bq/kg.

Dans les échantillons des 23 au 26 juin 2015, du Cs-134 a été relevé, ce qui prouve que ces boues séchées subissent aussi l’influence de l’accident de Fukushima.


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.
