摘要
本文调研了国内外有关小剂量电离辐射对生物体作用的实验研究。许多实验结果指出,辐射引起生物体近期辐射损伤的阈值一般不低于01Gy,并且小剂量电离辐射对机体免疫功能有促进作用,小剂量预辐照后能对大剂量辐照产生适应性。因此,有学者提出小剂量有益的观点,很具有启发性。然而由于对小剂量辐射生物效应的资料掌握不够,对小剂量照射还需要继续进行深入的研究。
In this paper,the experiments of effects of ionizing radiation at low dose on the living beings at home and abroad were investigated.It was found that the dose threshold value leading to injury of the living beings usually is no less that 0.1Gy.Low dose ionizing radiation promotes immune effects of living beings and the living beings with pre exposure of low dose can result in adaptive response to post hihger dose.Therefore low dose is harmless,advantageous and good.
