[Confused report] “No decontamination is needed because the ATMOSPHERIC DOSE is less than 10,000 Bq/h”.

Asahi newspaper is confused.

21,567 Bq/Kg of cesium was measured from the black substance found in Chichibu city Saitama by citizen’s radiation monitoring organization.

From the following up test with Chichibu city and Ogano machi local government, 13,000 ~ 19,000 Bq/Kg of cesium was measured.

It’s reported by Asahi newspaper that the governmental staff in charge commented like this below,

The atmospheric dose is lower than the safety limit of 10,000Bq/h. (so decontamination is not needed.)

[Rapport confus] “Aucune décontamination n’est nécessaire puisque la RADIOACTIVITÉ ATMOSPHÉRIQUE est à moins de 10 000 Bq/h”.

Le journal Asahi est confus.

21 567 Bq/kg de césium ont été relevés dans de la substance noire trouvée dans la ville de Chichibu, préfecture de Saitama, par une organisation citoyenne de surveillance de la radioactivité.
Du suivi opéré par les autorités municipales de Chichibu et préfectorales d’Ogano machi, de 13 000 à 19 000 Bq/kg de césium ont été relevés.

Il est rapporté par le journal Asahi que l’équipe gouvernementale responsable en aurait dit ceci :

La radioactivité atmosphérique est inférieure à la limite de sécurité de 10 000 Bq/h. (donc, pas besoin de décontaminer.)


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.
