On April 29, 2011, we started sampling surveys of the seawater at 5 points
in the 3km offshore area of Ibaraki Prefecture. 

Since June 3, 2011, we have conducted sampling surveys of lower layer of
the seawater. 
                                                    (Previously announced)

Today we conducted a nuclide analysis of radioactive materials in the
seawater sampled on August 26 and 27. As a result, no radioactive material
was detected as described in the appendix. We reported the results to
Nuclear and Industrial Safety Agency and the government of Ibaraki
Prefecture today.

We will continuously conduct the similar sampling.
