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. (previously announced)

On March 30th, 2011, we conducted nuclide analysis of radioactive 
materials contained in the air which were collected on the same date at 
the site of Fukushima Daiichi Nuclear Power Station. As a result, 
radioactive materials were detected as shown in the attachment. Therefore, 
we summarized the results and reported them to Nuclear and Industry Safety 
Agency as well as to the government of Fukushima Prefecture today.

We are planning to conduct these surveys continuously.
