摘　　要：用γ谱方法测定了核电站运行前后大亚湾海域一些海洋生物、海水、沉积物的１３７Ｃｓ含量。计算了海洋生物对１３７Ｃｓ的浓集因子与１３７Ｃｓ在沉积物和海水之间的分配系数。结果表明：与发电前相比，核电站运行一年后三种样品中的１３７Ｃｓ含量没有明显的变化。The contents of 137 Cs in some marine organisms, seawaters and sea sediment in Dayawan area were measured by γ spectrometer. The concentration factors for the marine organisms and distribution coefficient between sediment and seawater have been calculated. The results shown that the apparent deferences 137 Cs contents in samples after and before the operation of Dayawan Nuclear Power Plant were not found.
