2,700,000,000 Bq/m3 of Strontium-90 measured from groundwater nearby Reactor 2

Following up this article.. Strontium-90 detected from seawater of Fukushima plant port in 95% of the tests [URL]


Extremely high level of Strontium–90 was measured from groundwater of various places in Fukushima plant area, according to Tepco.

The sampling date was from this January to March. Sr-90 was measured from all of the 30 measurements.

Newer data hasn’t been published.


The most contaminated area was the seaside of Reactor 2.

The highest reading was 2,700,000,000 Bq/m3. Even the second highest reading was 1,900,000,000 Bq/m3.


Tepco doesn’t mention the most likely cause, however at least it is clear that the “large” area of Fukushima plant has Sr-90 contamination spreading.

Selon Tepco, une radioactivité extrêmement élevée en strontium 90 a été relevée dans les eaux souterraines  en différents endroits de la centrale nucléaire de Fukushima.
Les échantillons ont été pris entre janvier et mars derniers. Du Sr 90 a été relevé dans les 30 mesures.
Pas de données publiées plus récentes.

La zone la plus radioactive est le côté mer du réacteur 2.
Le record relevé es de 2 700 000 000 (2,7 milliards de) Bq/m³. La deuxième place est à 1,9 milliards de Bq/m³.

Tepco ne mentionne pas la cause la plus probable mais au moins il est clair que “le gros” de la centrale de Fukushima diffuse du Sr 90.

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.
