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 analysis in the soil from the samples at the 3 
periodic sampling spots collected on June 13, June 16, June 20 and June 23, 
plutonium 238, 239, and 240 were detected as shown in the attachment 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 attachment 2.

In addition, as a result of strontium analysis in the soil from the samples 
at the 3 periodic sampling spots collected on June 13, strontium 89 and 90 
were detected as shown in the attachment 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.
