We had been studying to implement sampling surveys on the ocean soil, 
completed preparations and conducted the surveys on April 29, 2011. 
                                     (Previously announced on May 3, 2011)

We conducted nuclide analysis for the ocean soil sampled on September 26,
27 and 28. As a result, radioactive materials were detected as shown in
the appendix.

Today, we reported the results to NISA and the government of Fukushima 
Prefecture.

We will continuously conduct the same sampling surveys.
