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.
As a result of nuclide analysis of gamma rays contained in the soil
collected on December 5, 2011 at the 3 places where we collect samples
periodically, radioactive materials were detected as shown in attachment.
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.
