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 have informed the result to Nuclear and
Industrial Safety Agency (NISA) and Fukushima prefecture.
(previously announced)
On March 30th 2011, we have conducted re-sampling survey to examine the
effect of radioactive materials in the seawater. Today, we have 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 similar sampling survey.
