Press Release (Mar 28,2011)
Detection of radioactive material in the soil in Fukushima Daiichi Nuclear Power Station

---

On March 28th 2011, 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 as shown in the attachment.

We will continue the radionuclide analysis contained in the soil.

‹Results of the analysis›

-Plutonium was detected in the soil of Fukushima Daiichi Nuclear Power 
 Station.
-The density of detected plutonium is equivalent to the fallout observed 
 in Japan when the atmospheric nuclear test was conducted in the past.
-The detected plutonium from two samples out of five may be the direct 
 result of the recent incident, considering their activity ratio of the 
 plutonium isotopes.
-The density of detected plutonium is equivalent to the density in the 
 soil under normal environmental conditions and therefore poses no major 
 impact on human health. TEPCO strengthens environment monitoring inside 
 the station and surrounding areas.
-We will conduct analysis of the three additional soil samples.
