Press Release (Jun 12,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (79th release)
 
On March 22, 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 11, 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.
