The results of nuclide analyses of radioactive materials in the ocean soil off the coast of Fukushima Daiichi Nuclear Power Station (continued report 34)

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)

As a result of plutonium analysis and uranium analysis in the ocean soil^* 
sampled on September 8, 9, 13 and 25, 2011, plutonium 239 and 240 and 
uranium 234, 235 and 238 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.

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