^60Co-γ射线对成体长牡蛎生长的影响及致死效应
Effects of ionizing irradiation of ^60Co-γ ray on mortality and growth of one year-old Pacific oysters ( Crassotrea gigas ) were studied. Irradiation was conducted at 4℃ and without sea water, and the survival, shell length, shell width, whole wet weight and condition index of irradiated oysters wer...
