Press Release (Apr 14,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (20th release)
 
On March 22nd 2011, as part of monitoring activity of the surrounding
environment, 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
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 13th 2011, we conducted a nuclide analysis of radioactive
materials contained in the air which were 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 exhibit.
Accordingly, we have reported the result of the analysis to NISA and the
government of Fukushima Prefecture.

We are planning to conduct these surveys continuously.
