On March 22nd 2011, as part of monitoring activity of the surrounding
environment, we conducted nuclide analysis of radioactive materials
contained in the air which were collected on March 20th and 21st 2011 at
the site of Fukushima Daiichi Nuclear Power Station, which was damaged by
Tohoku-Chihou-Taiheiyo-Oki Earthquake. As a result, radioactive materials
were detected as shown in the attachment. Therefore, we summarized the
results and reported them to Nuclear and Industry Safety Agency as well as 
to the government of Fukushima Prefecture today. (previously announced)

On March 28th, 2011, we conducted nuclide analysis of radioactive
materials contained in the air which were collected on the same date at
the site of Fukushima Daiichi Nuclear Power Station. As a result,
radioactive materials were detected as shown in the attachment. Therefore,
we summarized the results and reported them to Nuclear and Industry
Safety Agency as well as to the government of Fukushima Prefecture today.

We will continue the sampling survey the same as this one.
