All β density of groundwater jumped up by 6557 times after the Typhoon / 400,000,000 Bq/m3 highest ever

All β density and Tritium density in groundwater jumped up after the Typhoon near the tank that experienced 300m3 of leakage.

All β density was 400,000,000 Bq/m3 on 10/17/2013. It was 90,000 Bq/m3 on 10/15/2013 and was 61,000 Bq/m3 on 10/16/2013.

Also, Tritium density was 790,000,000 Bq/m3 on 10/17/2013. It was 260,000,000 Bq/m3 on 10/15/2013.

Both of the readings are the highest ever.



Couldn’t make time to get the Donation button back on by 10/14/2013. It should be reposted tomorrow. Thank you for reading this.

La radioactivité β des eaux souterraines multipliée par 6 557 après le passage du typhon : 400 000 000 Bq/m³ – record absolu


La radioactivité β et celle du tritium des eaux souterraines proches de la citerne des 300 m³ a franchi un palier après le passage du typhon.

Le 17 octobre 2013, la radioactivité β était à 400 000 000 Bq/m³ (400 millions).
Le 15, elle était à 90 000 Bq/m³ et le 16 elle était à 61 000 Bq/m³ (moins de 100 000).

En outre, ce même 17 octobre, la radioactivité en tritium est à 790 000 000 Bq/m³ (790 millions).
Le 15, elle était de 260 000 000 Bq/m³ (260 millions).
Les deux relevés sont des records absolus.

Pas trouvé le temps de remettre les fonctions pour les dons au 14 octobre 2013. Ça devrait revenir demain. Merci de m’avoir lu.

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.
