Press Release (May 12,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (48th release)
 
On March 22nd, 2011, as a part of monitoring activity of the surrounding 
environments, we conducted nuclide analyses of radioactive materials 
contained in the air which were collected at the site of Fukushima Daiichi 
Nuclear Power Station, which was damaged by the Tohoku- Chihou-
Taiheiyou-Oki Earthquake. As a result, radioactive materials were detected 
and therefore, we summarized the results and reported them to Nuclear and 
Industry Safety Agency (NISA) as well as to the government of Fukushima 
Prefecture.
 
The analyses results of the three nuclides (Iodine-131, Cesium-134 and 
Cesium-137) are to be released as fixed figures, and the other nuclide 
figures are to be revaluated in accordance with the preventive measures 
formulated after the warning from NISA on April 1st.
                                                    (Previously announced)
 
On May 11th, 2011, we conducted nuclide analyses of radioactive materials 
contained in the air which was collected at the site of Fukushima Daiichi 
Nuclear Power Station on the same day. As a result, some radioactive 
materials were detected as described in the exhibit. Accordingly, today we 
have reported the result of the analyses to NISA and the government of 
Fukushima Prefecture.
 
We will continuously conduct the same sampling surveys.
