The severity of stochastic effects is independent of the absorbed dose . under certain exposure conditions , the effects may or may not occur . there is no threshold and the probability of having the effects is proportional to the dose absorbed 随机性效应随机性效应的严重程度是不受吸收剂量的大小影响。在一定的照射条件下,效应可能出现,也可能不出现,而发生的机率则与剂量大小有关,并且不存在剂量阈值。
It is generally believed that exposure of fetus at the first 3 weeks of pregnancy should not cause any deterministic and stochastic effect to the embryo . later stage irradiation of the fetus may leads to malformation of body organs and increase in cancer risk of the child 科学家通常认为在怀孕后最初三周内胎儿受到照射,是不会引起活产婴儿身上出现确定性或随机性效应。从受孕后三周到妊娠结束,照射可能会令正在发育的器官出现畸形及增加活产婴儿患癌症的机会。
