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 off the Pacific coast of Tohoku 
Earthquake.
This is the result of the sampling survey of radioactive materials in the 
seawater which was implemented as a part of monitorings of surrounding 
environment.
TEPCO had informed the result to Nuclear and Industrial Safety Agency 
(NISA) and Fukushima prefecture.
Details are as follows;
Re-sampling survey is scheduled tomorrow in the morning.
Same kind of sampling survey is scheduled at Fukushima Daini Nuclear Power 
Station to examine radioactive materials spread into the sea.

We would like to correct the information in "The result of the nuclide 
analysis of radioactive materials in the air at the site of
Fukushima Daiichi Nuclear Power Station" attached to the 
announcement "etection of radioactive materials from the seawater
around the discharge canal of Fukushima Daiichi Nuclear Power
Station" made on March 22nd. We deeply apologize for the 
inconvenience.
 
[Correction]
The place of collection
-Around the south discharge canal (approx. 330 m south from the
 discharge canalsa of Units 1 to 4) 
(False: Around the south discharge canal (approx. 100 m south from
 the discharge canals of Units 1 to 4))
