Press Release (Apr 09,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (15th release)
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.
                                                    (previously announced)

On April 8th 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.
