[100m3 overflow] All β detected 60m east from the tank / Contamination already penetrating to groundwater
Following up this article.. [100 m3 overflow] “Who turned on the wrong valve and why ?” / Still not identified [URL]
The contamination is possibly penetrating to groundwater already, according to Tepco.
One month after the overflowing accident, 120,000 Bq/m3 of all β nuclide to include Strontium-90 was detected from groundwater. The sample was taken in 60m east of the overflowed tank. The sampling depth was 10m.
Tepco admitted the overflowed contaminated water is already absorbed by the ground. They also measured 140,000 Bq/m3 of Tritium from the same sample.
Selon Tepco, la radioactivité se mélange déjà aux eaux souterraines.
Un mois après l’accident des 100 m³ ayant débordé, 120 000 Bq/m³ de radioactivité β – dont du strontium 90 – ont été relevés dans les eaux souterraines. L’échantillon a été pris à 60 m à l’est de la citerne qui a débordé et à 10 m de profondeur.
Tepco a reconnu que cette eau extrêmement radioactive est déjà absorbée par le sol.
Dans cet échantillon ils ont également relevé 140 000 Bq/m³ de tritium.
Le minimiser au début et ajouter tranquillement de nouvelles information pour que personne ne le remarque. Tout pour que le troupeau ne s’échappe pas. C’est leur stratégie.
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.
