A mistake has been found in "Detection of slight amount of radioactive 
materials by periodic radioactivity measurement at Kashiwazaki Kariwa 
Nuclear Power Station (update)" released at 4 pm today. We apologize and 
correct it as follows. 
 
 
 -"Analysis results of H-3 of seawater (Upper Layer) in recent survey 
  (2006 - 2010)"described at the bottom of table of Attachment 1 
  "Artificial radioactive materials detected from environmental radiation 
  monitoring samples collected around Kashiwazaki Kariwa Nuclear Power 
  Station in 2011"
 
  (Correct) H-3 Not Detectable-0.82
  (Mistake) H-3 Not Detectable-3.5
