As part of monitoring activity of the surrounding environment, we 
conducted 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)

Subsequently, from the 3 spots where periodic sampling was conducted on 
March 25th and 28th and from another spot which was supplemented on 25th, 
we conducted analysis of plutonium contained in the soil. As a result, 
plutonium 238, 239 and 240 were detected. 

In addition, we conducted nuclide analysis of gamma ray contained in the 
soil collected on March 21st and 22nd at the 5 spots in Fukushima Daiichi 
Nuclear Power Station. Such analysis was also conducted on soil collected 
on March 25th and 28th at the 4 spots. As a result, radioactive materials 
were detected as described in the exhibit. Accordingly, we have reported 
the result of analysis to Nuclear and Industrial Safety Agency and 
Fukushima Prefecture.

We will continue the radionuclide analysis contained in the soil.
