Detection of radioactive materials in the soil in Fukushima Daiichi Nuclear Power Station (15th release)
 
As part of monitoring activity of the surrounding environment, we conducted
an analysis of plutonium contained in the soil collected on March 21st and
22nd 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 analyses in the soil from the sample at the 3 
periodic sampling spots collected on May 15th, 19th, and 23rd, 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.

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.
