Nuclide analysis result of radioactive materials in the soil of Fukushima Daiichi Nuclear Power Station (28th release)
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 July 25, 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.
