Radiocesium concentrations were measured in the pectoralis muscles of great cormorant (n = 36) collected from Gunma Prefecture between November 2011 and July 2012. The 137Cs contamination levels in great cormorant were consistent with the 137Cs deposition levels on ground soil and 137Cs concentrations in freshwater fishes. The Tag of great cormorants were comparable with those of other birds except for copper pheasant.
