Strontium-90 density jumped up to be as double as the previous month reading again, according to Tepco.

The reading was 990,000,000 Bq/m3. The sample was taken on 10/2/2014. It was 490,000,000 Bq/m3 from the sample taken on 9/1/2014.

The sampling location was Reactor 2 seaside.

Tepco published only sporadic contamination data, and it doesn’t cover significant nuclides except Cs-134/137, Tritium and Strontium-90.

However even these carefully chosen data show the increasing trend of contamination situation of groundwater.

They haven’t announced what is actually likely to happen underground.
