Press Release (Jul 19,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (116th 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 July 18, 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, no radioactive materials 
were detected as described in the appendix. 

We will continuously conduct the same sampling surveys.
