Press Release (Nov 23,2011)
Nuclide Analysis Results of Radioactive Materials in the Air at the Site of Fukushima Daiichi Nuclear Power Station (243rd 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 was 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 theref
ore, 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 November 21 and 22, 2011, we conducted nuclide analysis of radioactive 
materials contained in the air which was collected at the site of 
Fukushima Daiichi and Daini Nuclear Power Stations.  As shown in the 
attachment, radioactive materials were detected.

We also conducted plutonium analysis contained in the air which was 
collected on November 7.  As shown in the attachment, no plutonium was 
detected.

We reported the above results to NISA as well as to the government of 
Fukushima Prefecture today.

We will continuously conduct the same sampling surveys.
