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 uranium analysis in the soil from the samples at the 2 out 
of the 3 periodic sampling spots collected on May 9, 16, 23 and 30, 
uranium 234, 235 and 238 were detected as shown in the attachment 1 to 4. 

In addition, since plutonium and uranium were detected as a result of the 
analysis in the soil from the samples at the 3 periodic sampling spots 
collected on May 9, americium and curium analysis in the soil was 
conducted. As a result of the analysis, americium 241 and curium 242, 243 
and 244 were detected as shown in the attachment 5. 

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.
