Abstract

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 T_ag of great cormorants were comparable with those of other birds except for copper pheasant.
