56,000 Bq/m3 of Strontium-90 measured from sub-drain of reactor2

According to Tepco, high level of Strontium-90 is still measured in sub-drain of reactor2 and 3. The data of reactor1 is not published for some reason.

The sampling date was 11/12/2012. Tepco took 6 months to publish the data.

They measured 56,000 Bq/m3 of Strontium-90 from sub-drain of reactor2. They also measured 67 Bq/m3 of Strontium-90 from sub-drain of reactor3.

They also measured significantly level of Tritium from both of the sub-drain.

It was 470,000 Bq/m3 in sub-drain of reactor2, 97,000 Bq/m3 in sub-drain of reactor3. From the one of reactor2, they also measured 430,000 Bq/m3 of all β nuclide.

Tepco admits it’s entirely due to Fukushima accident.

56 000 Bq/m³ de strontium 90 dans les évacuations du réacteur 2

 

Selon Tepco, on relève toujours un haut niveau en strontium 90 dans les évacuations des réacteurs 2 et 3. Les données concernant le réacteur 1 ne sont pas publiées.

L’échantillonnage date du 12 novembre 2012. Tepco a mis 6 mois pour les publier.
Ils ont relevé 56 000 Bq/m³ de strontium 90 dans les évacuations du réacteur 2. Ils ont aussi relevé 67 Bq/m³ de strontium 90 dans celles du réacteur 3.
Ils ont aussi relevé des niveaux importants de tritium dans les deux évacuations.
On avait 470 000 Bq/m³ dans l’évacuation du réacteur 2 et 97 000 Bq/m³ dans celle du réacteur 3.
Ils ont aussi relevé 430 000 Bq/m³ de β nucléides dans celle du réacteur 2.
Tepco admet que c’est entièrement du à l’accident de Fukushima.

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.
