As part of monitoring activity of the surrounding environment, we
conducted an analysis of plutonium contained in the soil collected on
March 21 and 22 at the 5 spots in Fukushima Daiichi Nuclear Power Station.
As a result, plutonium 238, 239 and 240 were detected.
(Previously announced)
As a result of nuclide analysis of plutonium contained in the soil
collected on October 31, 2011 at the 3 places where we collect samples
periodically, plutonium 238, 239, 240 were detected as shown in
appendix 1.
Also, as a result of nuclide analysis of gamma ray contained in the soil
collected on November 7, 2011, radioactivity material were detected as
shown in appendix 2
Today, we informed the Nuclear and Industrial Safety Agency and the
government of Fukushima Prefecture of the results.
We will continuously conduct the same sampling surveys.
