On March 22nd, 2011, as part of monitoring activity of the surrounding 
environment, 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.

On April 18th, 2011, we conducted a 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 the analysis to NISA and 
the government of Fukushima Prefecture.

We are planning to conduct these surveys continuously.
