摘要:
对60Co-γ射线诱发的长牡蛎(Crassostrea gigas)死亡效应随时间变化规律进行了研究,发现在10月份海区培育的条件下辐射诱发的长牡蛎死亡主要发生在处理后的24~36 d之间,在辐射后60 d内存活率达到稳定。同时,修复培育的环境因素对辐射致死效应可能产生一定的影响。

A primary report of lethal effect of 60Co-γ ray irradiation on adult Crassostrea gigas
Abstract:
Lethal effect of 60Co-γ ray irradiation on adult Pacific oyster, Crassostrea gigas, was reported in this paper. While their radiated animals were cultivated in the sea in autumn, the mortality mainly happened from 24th to 36th days after gammaray treatment. At this period, up to 56.16% of mortality was observed. Meanwhile, the ionizing radiation induced mortality of adult oyster was affected by cultivation condition.
Key words:  60Co-γ, irradiation  Crassostrea gigas  mortality
