Photo : Boring hole in seaside of Reactor 2.
Related to this article.. Tritium density of groundwater nearby the sea jumped up over 10 × [URL]
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.
(10/9 → 10/13, Bq/m3)
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
※ Highest reading in entire seaside groundwater
※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.
