Press Release (Aug 04,2011)
Nuclide Analysis Results of Radioactive Materials in the Air at the Site of Fukushima Daiichi Nuclear Power Station (132nd 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 August 3, 2011, we conducted nuclide analysis 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, radioactive materials 
were detected as described in the appendix 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. 

We conducted sampling for an analysis of strontium contained in the air on 
July 11. As a result, no strontium was detected as described in the 
appendix.  

We will continuously conduct the same sampling surveys.
