All β nuclide density to contain Strontium-90 became 100,000 times much since this February in groundwater.
Fukushima Diary found this in Tepco’s reported published on 10/10/2014.
It’s contaminated groundwater collected in the seaside of Reactor 2. According to Tepco, all β nuclide density was 10,000 Bq/m3 order from 11/2013 to 2/2014, however it got into the rapid increasing trend after 2/2014, and it’s become 1,000,000,000 Bq/m3 order in 9/2014.
Also, all β nuclide density from another boring of Reactor 2 seaside has been increasing since 11/2013, when Tepco started analyzing the sample from this boring. The density increased by 1,000 times much from 11/2013 to 9/2014.
Regarding these increases in all β nuclide density, Tepco hasn’t made any announcement. They are still stating most of it is stopped from leaking to the sea.
