Press Release (Jun 22,2011)
Detection of radioactive materials in the soil in Fukushima Daiichi Nuclear Power Station (19th 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 June 6 and June 9, 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.

As a result of americium and curium analysis in the soil from the samples
at the 3 periodic sampling spots collected on May 2, curium 242 was
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.
