Detection of Radioactive Materials from Subsurface Water near the Turbine Buildings of Fukushima Daiichi Nuclear Power Station
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 

Regarding sampling surveys of sub-drains, per the instruction from Nuclear 
and Industry Safety Agency (NISA) on April 14, we will continue 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, no plutonium was detected from the sample 
of sub-drains (subsurface water obtained and managed in the site) near the 
Unit 3 turbine building of Fukushima Daiichi Nuclear Power Station 
collected on July 18, 2011 as shown in the attachment.
