Detection of Radioactive Materials from Subsurface Water near the Turbine Buildings of Fukushima Daiichi Nuclear Power Station (Sampling: July 13)
On March 28 2011, we were advised from Nuclear Safety Commission of Japan 
to enhance sampling surveys regarding water accumulated in underground 
floor of the turbine buildings of Fukushima Daiichi Nuclear Power Station. 
In order to verify any leakages to underground and sea, and safety, we have
been implementing the sampling surveys of subsurface water and seawater.

Regarding sampling surveys of sub-drains, based on the instruction from 
Nuclear and Industry Safety Agency (NISA) on April 14th, we will continue 
conducting the same kind of sampling surveys three times a week, and inform
the result on the next day of the survey.
                                                    (Previously announced)

As a result of Nuclide analysis from the sample regarding sub-drains 
(subsurface water obtained and managed in the site) near the turbine 
buildings of Fukushima Daiichi Nuclear Power Station collected on July 13, 
radioactive materials were detected as shown in the attachment and today, 
we reported to NISA and the government of Fukushima Prefecture.
