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 analysis in the soil from the 
samples at the 3 periodic sampling spots collected on September 5 and 12, 
plutonium 238, 239, and 240 were detected as shown in the appendix 1.

In addition, as a result of nuclide analysis of the gamma ray contained in 
the soil, radioactive materials were detected as shown in the appendix 2 
and 3.

Today, we informed the Nuclear and Industrial Safety Agency and the 
government of Fukushima Prefecture of the results.

We will continue conducting the similar analysis.
