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 Plutonium and Strontium analyses in the soil collected on
October 17, 2011 at the 3 places where we collect samples periodically,
Plutonium 238, 239 and 240 were detected as shown in the appendix (1 & 2).

In addition, as a result of nuclide analysis of the gamma ray contained
in the soil collected on October 31, radioactive materials were detected
as shown in the appendix (3).

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.
