5 sorts of nuclide density reached the highest readings in a boring hole located in the seaside of Reactor 2 again. There is a possibility that Tepco damaged a crucial underground structure during the underground frozen water wall construction, but none of the media mentions this possibility as if there was a gag order. All the media announce this continuous increase of contamination level in groundwater can be due to the rainfall of the typhoon instead.

Those 5 sorts of nuclides are all that Tepco reports about to consist of Cs-134/137, Mn-54, Co-60 and all β nuclides.


Variety sorts of nuclides marked the highest density on 10/9/2014. (cf, Various nuclides density marked the highest level in groundwater from multiple locations of Fukushima plant [URL])

This is from the same boring hole and the record was already broken.

Cs-134 : 17,000,000 → 61,000,000 ※

Cs-137 : 51,000,000 → 190,000,000 ※

Co-60 : 2,100,000 → 3,600,000 ※

All β : 2,100,000,000 → 7,800,000,000 ※2

※2 Second highest reading in entire seaside groundwater


All the media announce this is due to the typhoon exactly as Tepco reports. However the increase is not seen in other neighboring borings, where actually had the same rainfall of the typhoon.

La radioactivité de 5 nucléides marque de nouveaux records sur le côté mer du réacteur 2

La radioactivité de 5 nucléides marque de nouveaux records dans un trou de forage situé coté mer du réacteur 2. Il est possible que Tepco ait endommagé une structure souterraine cruciale pendant leur construction du mur souterrain d’eau congelée mais aucun des organes de presse ne mentionne cette possibilité comme si c’était de l’ordre du gag. Au lieu de ça, tous les médias rapportent que cette augmentation continue de la radioactivité des eaux souterraines pourrait être due aux pluies du typhon.

Ces 5 nucléides sont tout ce que Tepco en rapporte et sont les Cs 134/137 (césiums), Mn 54 (manganèse), Co 60 (cobalt) et la radioactivité β totale.

Diverses sortes de nucléides ont battu des records le 9 octobre 2014. (cf. Différents radionucléides marquent des records dans les eaux souterraines en plusieurs endroits de la centrale de Fukushima)
Ceci provient d’un même trou de forage et le record est déjà battu.

(9 → 13 oct, Bq/m3)
Cs-134 : 17 000 000 → 61 000 000 (17 → 61 millions) ※
Cs-137 : 51 000 000 → 190 000 000 (51 → 190 millions) ※
Co-60 : 2 100 000 → 3 600 000 (2,1 → 3,6 millions) ※
Radioactivité β : 2 100 000 000 → 7 800 000 000 (2,1 → 7,8 milliards) ※²

※ Record pour toutes les eaux souterraines côté mer
※² Deuxième place pour toutes les eaux souterraines côté mer

Tous les médias disent que c’est à cause du typhon exactement comme le rapporte Tepco. Néanmoins, l’augmentation n’est pas constatée dans les trous de forage voisins sur lesquels est tombée la même quantité de pluie du typhon.


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.
