Sr-90 detected 6 times much as safety limit from seawater of water intake

According to Tepco, 170,000 Bq/m3 of Sr-90 was measured from seawater.

Density Limit Specified by the Reactor Regulation is 30,000 Bq/m3. The measurement reading is 5.7 times much as the density limit.

The sampling location is north of reactor 1-4 water intake.

Also, 120,000 Bq/m3 of Tritium was measured.

A la prise d’eau de mer, le strontium 90 détecté est 6 fois supérieur à la limite de sécurité

 

Selon Tepco, 170 000 Bq/m³ de Sr 90 ont été relevés dans l’eau de mer.

La limite de concentration spécifiée par la règlementation des réacteurs est de 30 000 Bq/m³. Le relevé est 5,7 fois au-dessus de cette limite.
L’échantillon provient de la prise d’eau au nord des réacteurs 1-4.
Ils ont aussi relevé 120 000 Bq/m³ de tritium.

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.
