Press Release (Apr 30,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (36th 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 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 April 29th, 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.
