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 28th 2011, we had conducted re-sampling survey to examine the
effect of radioactive materials in the seawater. Today, 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.
