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 October 14. As
a result, radioactive materials were detected as shown in the appendix.
Out of six sampling points, the sampling survey planned at one coastal sea
area yesterday was cancelled due to weather condition, etc.
Today, we reported the results to NISA and the government of Fukushima
Prefecture.
We will continuously conduct the same sampling surveys.
