On March 21st 2011, radioactive materials were detected from the seawater
around the discharge canal (south) of Fukushima Daiichi Nuclear Power 
Station which was damaged by the 2011 Tohoku-Taiheiyou-Oki Earthquake. 
This is the result of the sampling survey of radioactive materials in the 
seawater which was implemented as a part of monitoring activity of 
surrounding environment. We had informed the result to Nuclear and 
Industrial Safety Agency (NISA) and Fukushima prefecture.
(previously announced)

On March 24th 2011, we had conducted re-sampling survey to examine the 
effect of radioactive materials in the seawater. We had informed the 
result to Nuclear and Industrial Safety Agency (NISA) and the government 
of Fukushima Prefecture, because radioactive materials were detected as 
shown in the attachment.

We will continue to conduct same kind of sampling survey.
