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 a nuclide analysis of radioactive materials contained in the
ocean soil sampled on November 18. As a result, radioactive materials were
detected as shown in the attachment.
Due to the bad weather condition, we did not conduct the sampling at 1 off-
coast out of 5 locations which was planned the day before yesterday.
Today, we reported the results to NISA and the government of Fukushima
Prefecture.
We will continuously conduct the same sampling surveys.
