Still high density of Strontium-90 is detected from groundwater of Reactor 2 seaside, Tepco reported on 2/6/2015.

Tepco took groundwater samples at 9 wells situated in seaside of Reactor 2 from 1/5/2015 to 1/6/2015.

As a result, the highest reading was 590,000,000 Bq/m3, which increased 18% from December’s reading of this well.

The second highest reading was 520,000,000 Bq/m3, which also increased 8% from December’s reading of this well.

Strontium-90 was detected from all the 9 wells.

Tepco hasn’t released other analysis results for some reason.

Le 6 février 2015, Tepco rapporte qu’ils relèvent toujours une très forte radioactivité en strontium 90 dans les eaux souterraines du côté mer du réacteur 2.
Tepco a près des échantillons d’eau souterraine sur 9 puits de forage du côté mer du réacteur 2 entre le 5 et le 6 janvier 2015.
Au bout du compte, le record en est de 590 millions (590 000 000) de Bq/m³, ce qui le porte à 18 % au-dessus des relevés de décembre pour le même forage.
Le second relevé record est de 520 millions (520 000 000) de Bq/m³, ce qui a aussi augmenté, de 8 %, depuis les relevés de décembre de ce forage-là.
Le strontium 90 a été relevé dans l’ensemble des 9 puits de forage.
Tepco n’a pas publié d’autres résultats d’analyse.


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.
