Tepco has analyzed only 5 samples of fish outside the port from April to June for Sr-90 from their announcement released on 9/9/2015.

The sampling area was 20km radius area from Fukushima nuclear plant except the port.

Additionally, the samples cover only 3 types of fish (Stingray, Marbled sole, and Microstomus
achne). Sr-90 is known to be accumulated in the bones but they analyzed only the muscle part for some reason. However, Sr-90 was detected from all of the samples.

Cs-134/137 was detected from all of the samples as well. The highest reading was 256 Bq/Kg, which is 2.5 times higher than food safety limit.

Au premier trimestre 2015 et hors du port de la centrale, Tepco n’a recherché le strontium 90 que dans 5 poissons

Selon leur rapport du 9 septembre 2015, entre avril et juin Tepco n’a analysé le strontium 90 que dans 5 échantillons de poissons pris en dehors du port de la centrale.

La zone échantillonnée s’étend sur 20 km de rayon autour de la centrale nucléaire de Fukushima, le port excepté.
En outre, les échantillons ne concernent que 3 types de poissons (Pastenague, sole marbrée, et Microstomus achne).
Le strontium 90 est connu pour s’accumuler dans les os mais ils n’ont analysé que les tissus musculaires.
Malgré ce, le Sr-90 a été relevé dans tous les échantillons.

Du césium 134/137 a également été relevé dans tous les échantillons.
Le relevé record est de 256 Bq/kg, soit plus de 2,5 fois la limite de la sécurité alimentaire.


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.
