[Strontium90] 490 Bq/Kg of Strontium-90 measured from the soil of Fukushima nuclear plant
According to Tepco, high level of Strontium-90 was measured from the dry soil of Fukushima nuclear plant.
The highest reading was 490 Bq/Kg from 500m in North of reactor1&2 stacks. The sample was taken on 9/10/2012. Tepco has not announce the result for over 7 months.
From the sample taken on 10/15/2012, 460 Bq/Kg of Sr-90 was measured in the same location.
Tepco has not made any explanation about why they took 7 months to release the data.
[Strontium 90] 490 Bq/kg de strontium 90 dans le sol de la centrale nucléaire de Fukushima
Selon Tepco, ils ont relevé de hauts niveaux de strontium 90 dans le sol sec de la centrale nucléaire de Fukushima.
Le record a été de 490 Bq/kg à 500 m au Nord de deux piles du réacteur 2. L’échantillon date du 10 septembre 2012. Tepco n’a pas communiqué ce résultat pendant plus de 7 mois.
Un échantillon du 15 octobre 2012 montre 460 Bq/kg de Sr 90 au même endroit.
Tepco ne donne aucune explication sur ce délai de 7 mois pour communiquer ces données.
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.
