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 10, 2011 at the 3 places where we collect samples periodically,
Plutonium 238, 239 and 240, and Strontium 89 and 90 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 17 and 24, radioactive materials were
detected as shown in the appendix (3 & 4).

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.
