Combined action of ultraviolet (UV) light and alpha-particles on yeast cells of different genotypes has been studied. Under combined action, after small doses of UV-light the oscillated changes of cell survival were registered for wild-type cells independent of the ploidy and the sequence of application of radiations. Additive effect of high doses of UV-light and ionizing radiation was expressed for strains incapable of the recovery of damages induced by ionizing radiation. For yeast cells possessing such a capability, the synergistic interaction of damages inflicted by high doses of UV-light and alpha-particles was noted. Possible reasons of the observed cell responses are discussed.
研究了紫外线（UV）和α粒子对不同基因型酵母细胞的联合作用。在联合作用下，对于野生型细胞，小剂量紫外线照射后，无论其倍性和辐射应用顺序如何，细胞存活率均呈现振荡变化。对于无法修复电离辐射诱导损伤的菌株，高剂量紫外线和电离辐射表现出相加效应。对于具有这种修复能力的酵母细胞，高剂量紫外线和α粒子造成损伤之间存在协同相互作用。文中讨论了观察到的细胞反应的可能原因。
