Press Release (Nov 01,2011)
Confirmed results of the nuclide analysis at Fukushima Daiichi Nuclear Power Station (For samples taken from October 1 to October 15)
We have carried out nuclide analysis of the samples taken daily at certain 
points of Fukushima Daiichi nuclear Power Station (such as the atmosphere 
in the station site or seawater around the station), determined the 
radiation dose of the three main nuclides* and have reported provisional 
results to the Nuclear and Industry Safety Agency (NISA) of the Ministry 
of Economy, Trade and Industry (METI), as well as the Fukushima Prefecture.
Also, we will reevaluate and compile the nuclide analysis results on the 
main three nuclides and other nuclides as confirmed results and report 
them to the NISA of METI and the Fukushima Prefecture.

                      (Previously announced on April 4 and April 20, 2011)

We reevaluated the nuclide analysis results of the samples taken during 
October 1 - 15 from the atmosphere in the station site, seawater / marine 
soil around the station, seawater around the intake of Unit 1 to 4, 
sub-drain water around the turbine buildings, sub-drain water around the 
Centralized Radiation Waste Treatment Facility and seawater offshore of 
Ibaraki and Miyagi Prefectures. Today we reported the confirmed results 
to the NISA of METI and the Fukushima Prefecture. 

We will also reevaluate and report nuclide analysis results on atmosphere 
in the station site, seawater around the station, etc. taken on and after 
October 16.

*the three main nuclides are Iodine-131, Cesium-134 and Cesium-137.
