Press Release (Sep 06,2011)
Nuclide Analysis Results of Radioactive Materials in the Air at the Site of Fukushima Daiichi Nuclear Power Station (165th 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 September 5, 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. As a result,
radioactive materials were detected as described in the appendix.
Sampling on the south breakwater and mega float at Fukushima Daiichi
Nuclear Power Station, which was planned for yesterday, was cancelled due
to the weather condition.

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.
