222,495 Bq/Kg from street gutter mud of public hall in Fukushima city, 66km from Fukushima nuclear plant
In the end of May, significantly high level of radiation was measured from the street gutter mud in Setagaya Tokyo.
(cf, 18,756 Bq/kg of Cs-134/137 measured from the mud in street gutter in Setagaya Tokyo [URL])
The citizens’ radiation laboratory CRMS (Citizen’s Radioactivity Measuring Station) also measured extremely high level of radiation from street gutter mud in Fukushima city. The location is Fukushima city public hall, where is 66km in North West from Fukushima nuclear plant.
The sample was not dried. The reading may be higher in dry soil.
Sampling date was 5/1/2013.
Cs-134 : 75,755 Bq/Kg
Cs-137 : 146,740 Bq/Kg
Total : 222,495 Bq/Kg
Atmospheric dose : 3.80 μSv/h (1m from the ground), 13.70 μSv/h (On the ground)
Le laboratoire civil de surveillance CRMS (Citizen’s Radioactivity Measuring Station) a aussi relevé une radio activité extrêmement élevée dans la boue d’un caniveau de la ville de Fukushima. C’est dans un hall public de la ville, qui se trouve à 66 km au nord-ouest de la centrale nucléaire de Fukushima.
Ce n’était pas un échantillon sec. Le relevé serait encore plus fort sur sol sec.
Date : 1er mai 2013. Cs-134 : 75 755 Bq/kg Cs-137 : 146 740 Bq/kg Total : 222 495 Bq/kg
Air ambiant : 3,80 μSv/h (à 1 m du sol), 13,70 μSv/h (au sol)
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.
