Following up this article.. Tepco had been wrongly analyzing Strontium-90 since 2003 [URL]


From Tepco’s own data, Strontium-90 detection used to be very rare before 311.


According to Tepco, the measurement instrument had been analyzing 755 nuclear waste samples from 2003 to 311. However, Strontium-90 was measured from only one sample, and the reading was only 0.00014 Bq/m3.


It’s often said that those radionuclides flew from Chernobyl, not from Fukushima accident. However this is denying the hypothesis.

Dans la centrale de Fukushima Avant le 11-3, il n’y avait eu du strontium 90 détecté que dans un des 755 déchets nucléaires analysés

Selon les propres données de Tepco, il était très rare de détecter du strontium 90 avant le 11-3.

Selon Tepco, entre 2003 et mars 2011 l’instrument de mesure a analysé 755 échantillons de déchets nucléaires. Or, il n’a trouvé du strontium 90 que dans un seul et qui ne titrait qu’à 0,00014 Bq/m³.

Il a souvent été affirmé que ce radionucléide était dérivé de Tchernobyl, pas de l’accident de Fukushima. Ceci vient balayer cette hypothèse.

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.
