Press Release (Apr 20,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (26th 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 19th, 2011, we conducted nuclide analyses of radioactive 
materials contained in the air which were collected at the site of 
Fukushima Daiichi Nuclear Power Station on the same day. As a result, 
radioactive materials were detected as described in the exhibit. 
Accordingly, on April 20th, we have reported the result of the analysis to 
NISA and the government of Fukushima Prefecture.

We are planning to conduct these surveys continuously.
