Highest density of Tritium detected from 25m underground / 3,100,000 Bq/m3

Extremely high density of Tritium was detected from groundwater of deep layer.

 

Tepco has started building the frozen water underground wall. In order to investigate the groundwater contamination outside of the wall, Tepco took sample from 25m underground.

As a result, 3,100,000 Bq/m3 of Tritium was measured from the sample taken near reactor2. The sampling date was 5/28/2014. From Fukushima Diary’s research, this is the highest reading since they started measuring.

 

They measured Strontium-90 from the same deep layer beside reactor4 last November.

There is a possibility that contaminated water is traveling under the sea bottom of Fukushima port to come up offshore.

Record de tritium relevé à 25 m en sous-sol : 3,1 millions de  Bq/m³

 

Une radioactivité extrêmement importante de tritium a été relevée dans les eaux souterraines de la couche profonde.

Tepco a commencé la construction du mur congelé souterrain. Pour examiner la contamination des eaux souterraines en dehors de l’enceinte de ce mur, Tepco a pris un échantillon à 25 m de profondeur.
Au final, ils ont relevé 3 100 000 Bq/m³ de tritium dans un échantillon pris près du réacteur 2. L’échantillon est du 28 mai 2014. Selon les recherches du Fukushima Diary, c’est le record depuis qu’ils ont commencé leurs mesures.

En novembre dernier ils avaient relevé du strontium 90 dans cette même couche profonde à côté du réacteur 4.
Il est probable que ces eaux extrêmement radioactives s’écoulent sous le fond marin du port de la centrale de Fukushima pour ressurgir au large.

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.
