摘要

为配合空间辐射生物学效应研究，本文采用卤虫（,Artemia salina,）卵作材料，在地面研究快中子和γ辐照对卤虫卵发育的影响。中子辐照剂量为10、50，100、200、400、600、800和1 000 Gy；γ辐照剂量为50、100、500、1000和2 000 Gy。实验结果表明：（1）电离辐射引起卤虫卵早期发育速度变慢；（2）虫卵受辐照后，冒出率和孵出率随剂量的增高而下降，且随辐照后保存时间的延长，效应继续加剧；（3）受辐照虫卵孵出幼虫的死亡率高峰出现在孵出后的第2—5 d之间；其LD,50,在中子与γ射线之间的相对生物效应（RBE）为1.80（第3 d），2.44（第4d）和2.27（第5 d）。

Abstract

For accompanying with space radiobiological studies,dry eggs of native ,Artemia, were irradiated in the laboratory by 14 Mev fast neutrons and ,60,Co γ-rays, and their development was then followed. Doses of the fast neutrons used were 10,50 100,200,400,600,800 and 1000 Gy, and those of γ-rays were 50,100,500,1000 and 2000 Gy respectively. The irradiated eggs, together with the control, were stored at 4℃ before incubation and observations.,The results are as follows: (1) A significant delay of early development was seen in eggs irradiated by both radiations. (2) The rates of emergence and hatching decreased with the increase of the doses, and went down further after the prolongation of egg-storage at 4℃. (3) The mortality peak of the larvae hatched from irradiated eggs appeared within 2—5 days after hatching, and the RBE's of the fast neutrons, for LD,50, comparing with the γ-rays were found to be 1.80 on the 3 rd day, 2.44 on the 4th day, and 2.27 on the 5th day.
