Tritium density of groundwater nearby the sea jumped up over 10 ×

Tritium density in groundwater of another boring rapidly increased to be 10 times much as 1 week ago, which is the highest reading from this boring hole.

The boring is also located in the seaside of Reactor 2. The sample was collected on 10/9/2014 as well.

Tritium density was 14,000,000 Bq/m3 on 10/2/2014, however it was 150,000,000 Bq/m3 on 10/9/2014.


Tepco states it can be due to the rainfall of the typhoon. However, there are 34 boring holes on the seaside of Reactor 1 ~4 and the rapid increases of radioactive density were observed in only 3 of them.

La radioactivité en tritium des eaux souterraines proches de la mer s’est multipliée par plus de 10

La radioactivité en tritium des eaux souterraines d’un autre forage a rapidement augmenté pour être 10 fois ce qu’elle était la semaine dernière, c’est le record pour ce forage.
Ce forage est aussi situé sur le côté mer du réacteur 2. L’échantillon est du 9 octobre 2014.
La radioactivité en tritium en était de 14 000 000 Bq/m³ (14 millions, déjà) le 2 octobre 2014, néanmoins, elle passe à 150 000 000 Bq/m³ (150 millions) le 9 octobre 2014.

Tepco affirme que ce serait à cause des pluies du typhon. Il y a cependant 34 puits de forage sur le côté mer des réacteurs 1 à 4 et cette augmentation brusque de la radioactivité ne concerne que 3 d’entre eux.

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.
