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
November 17 – December 1 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, seawater offshore of
Ibaraki and Miyagi Prefectures, fallout inside and outside the plant site.
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
December 2.
 
*the three main nuclides are Iodine-131, Cesium-134 and Cesium-137. 
 
*The dates underlined indicated one day before the correct dates.
 The aforementioned corrections are given. (January 14, 2012)
