Press Release (Apr 24,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (30th release)
On March 22nd, 2011, as a part of monitoring activity of the surrounding
environments, we conducted nuclide analyses of radioactive materials 
contained in the air which were 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 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 in accordance with the preventive measures formulated after the
warning from NISA on April 1st.
(Previously announced)

On April 23rd, 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, some
radioactive materials were detected as described in the exhibit. 
Accordingly, today we have reported the result of the analyses to NISA and
the government of Fukushima Prefecture.

We will continuously conduct the same sampling surveys.
