Groundwater Cs-134/137 density jumped up 260 percent beside Reactor 2 within only a week

On 9/29/2015, Tepco announced Cesium-134/137 density of groundwater rose up to 260% of the previous highest reading beside Reactor 2.


This is the groundwater pumped up in the seaside of Reactor 2. The sample was collected on 9/28/2015.

The previous highest reading was 1,170 Bq/L, which was detected one week ago. However it went up to 2,990 Bq/L in total of Cs-134/137.

Sr-90 density is still under analysis.

Le 29 septembre 2015, Tepco annonce que la radioactivité en césium 134/137 des eaux souterraines a augmenté de 260 % par rapport au précédent record relevé à côté du réacteur 2.

Il s’agit des eaux souterraines pompées du côté mer du réacteur 2.
L’échantillon est du 28 septembre 2015.
Le record précédent, de 1 170 Bq/L, avait été relevé il y a une semaine.
On atteint maintenant 2 990 Bq/L au total pour le Cs 134/137.
La radioactivité du strontium 90 est en cours 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.
