Press Release (Oct 08,2011)
Nuclide Analysis Results of Radioactive Materials in the Air at the Site of Fukushima Daiichi Nuclear Power Station (197th 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 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 October 7, 2011, we conducted a nuclide analysis of radioactive 
materials contained in the air which was collected at the site of Fukushima 
Daiichi and Daini Nuclear Power Stations (NPS). As shown in the attachment, 
radioactive materials were not 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.
