Following up this article.. 60,000 Bq/m3 of Strontium-90 detected from groundwater of 25m underground [URL]


On 1/31/2014, Tepco announced they measured 36,000 Bq/m3 of Strontium-90 from the upper permeable layer.

It has been reported Strontium-90 was detected in the deeper permeable layer of 25m underground. Now it’s confirmed that Strontium-90 is already spreading in every layer of underground.


The sample was taken last November. Usually Strontium-90 analysis doesn’t take longer than a month. Tepco’s reports about Strontium-90 are still behind the schedule.

Le 31 janvier 2014, Tepco annonce qu’ils ont relevé 36 000 Bq/m³ de strontium 90 dans la plus haute des couches perméables.
Il avait été rapporté que du strontium 90 avait été relevé dans la couche perméables la plus profonde à 25 m sous le sol. A présent, il est confirmé que le strontium 90 se répand déjà dans toutes les autres couches.

L’échantillon date de novembre dernier. Habituellement, l’analyse du strontium 90 ne prend pas plus d’un mois. Les rapports de Tepco sur le strontium 90 sont toujours attendus.

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.
