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 analyses results of 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.
(Previously announced)

On June 7, 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 
appendix. Accordingly, today we have summarized the results and 
reported them to NISA and the government of Fukushima Prefecture.

We will continuously conduct the same sampling surveys.
