19,000 Bq/Kg from the drain of balcony in Setagaya Tokyo, May 2013

 

On 6/6/2013, Fukushima Diary reported “18,756 Bq/kg of Cs-134/137 measured from the mud in street gutter in Setagaya Tokyo [URL]”

From the detailed report of CRMS (Citizen’s Radioactivity Measuring Station), it was not a street gutter, but the drain of a balcony.

It was a second floor veranda of a private house in Setagaya Tokyo. There is no roof over it.

The area had not been throughly cleaned since 311. The sample was 1cm ~ 2cm of the upper layer of the mud.

The radiation level was 0.089 μSv/h at 1m from the floor, but it was 0.332 μSv/h at 1cm from the mud.

It has been over 2 years since 311. Radioactive material is still accumulated even in Tokyo.

19 000 Bq/kg dans l’évacuation d’un balcon à Setagaya dans Tokyo, mai 2013

 

19,000 Bq/Kg from the drain of balcony in Setagaya Tokyo, May 2013

Le 6 juin 2013, le Fukushima Diary publiait 18 756 Bq/kg de césium 134/137 relevés dans la boue d’un caniveau de Setagaya dans Tokyo

Il ressort du rapport détaillé du CRMS (Citizen’s Radioactivity Measuring Station), que ce n’était pas dans un caniveau mais depuis l’écoulement d’un balcon.
C’est au deuxième étage, dans une véranda d’une maison privée de Setagaya à Tokyo. Il n’y a pas de toit au-dessus.
L’endroit n’a pas été entièrement nettoyé depuis le 11-3. L’échantillon était issu des 1 à 2 cm de la couche supérieure de la boue.
Le niveau de radioactivité était de 0,089 μSv/h à 1 m du sol mais il passait à 0,332 μSv/h à 1 cm de la boue.
2 ans sont passés depuis le 11-3. La radioactivité s’accumule encore même dans 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.
