31,000,000 Bq/m3 of Strontium-90 measured at the nearest boring well to Reactor 2

On 1/27/2015, Tepco announced they measured high density of Strontium-90 from groundwater in the seaside of Reactor 2.

It was 31,000,000 Bq/m3. The sampling point was the boring well, which is the closest to Reactor 2.

This is the highest density measured from this boring well, which is 10% more than the previous highest record.

The sampling date was last December. No Sr-90 data of January has been published.

31 millions de Bq/m³ de strontium 90 au forage le plus proche du réacteur 2


Le 27 janvier 2015, Tepco annonce qu’ils ont relevé une forte radioactivité en strontium 90 dans les eaux souterraines du côté mer du réacteur 2.

C’était à 31 000 000 Bq/m³. L’échantillon provient du puits de forage qui est le plus proche du réacteur 2.
C’est le record de radioactivité pour ce forage, il est supérieur de 10 % du record précédent.
L’échantillon date de décembre dernier. Aucune donnée sur le Sr 90 n’a encore été publiée pour janvier.


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.
