On March 22nd 2011, as part of monitoring activity of the surrounding 
environment, we conducted nuclide analysis of radioactive materials 
contained in the air which were collected at the site of Fukushima 
Daiichi Nuclear Power Station, which was damaged by 
Tohoku-Chihou-Taiheiyo-Oki Earthquake. As a result, radioactive materials 
were detected and therefore, we summarized the results and reported them 
to Nuclear and Industry Safety Agency as well as to the government of 
Fukushima Prefecture.

Three nuclides (Iodine-131, Cesium-134 and Cesium-137) are released as 
fixed figures. Other nuclides figures are to be released as soon as 
identified under instruction of NISA.

On April 5th 2011, we conducted nuclide analysis 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, we have 
reported the result of analysis to Nuclear and Industrial Safety Agency 
and Fukushima Prefecture.

We are planning to conduct these surveys continuously.
