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 analysis for americium as well as curium because plutonium 
and uranium were detected from the ocean soil* sampled on September 8, 9, 
12, 13, 15 and 25. As a result, Americium 241 was 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.

*The results of nuclide analysis for 3 major nuclides (I-131, Cs-134, 
 Cs-137) were previously announced on September 9, 10, 13, 14, 16 and 26.
