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 Pu analysis and nuclide analysis of the gamma ray contained 
in the soil collected on September 26, 2011 at the 3 places where we 
collect samples periodically, plutonium 238, 239, 240 and cesium 134, 137 
were detected as shown in the appendix.
 
Today, we informed the Nuclear and Industrial Safety Agency and the 
government of Fukushima Prefecture of the results.
 
We will continuously conduct the same sampling surveys.
