The effects of gamma rays and electron beams on the germination, outgrowth and the synthesis of protein and RNA of Bacillus pumilus spores were investigated to clarify the difference in the effects of the two types of radiations on bacterial spores. Gamma irradiation facilitated the germination to a slightly larger degree than electron irradiation. The outgrowth, growth and the synthesis of protein and RNA were inhibited by gamma irradiation to a greater extent than electron irradiation, when the spores were irradiated at the same dose. However, the effects of the two types of radiations were the same when the spores were irradiated with electron beams at a dose 30% higher than gamma rays. The results indicate that the effects of electron beams on bacterial spores and those of gamma rays are qualitatively the same but quantitatively different.
研究了γ射线和电子束对短小芽孢杆菌孢子萌发、芽孢杆菌生长以及蛋白质和RNA合成的影响，以阐明这两种辐射对细菌芽孢影响的差异。γ辐射比电子辐射在促进萌发方面的程度稍大。当以相同剂量照射孢子时，γ辐射比电子辐射在更大程度上抑制芽孢杆菌生长、生长以及蛋白质和RNA的合成。然而，当以比γ射线高30%的剂量用电子束照射孢子时，两种辐射的效果相同。结果表明，电子束对细菌芽孢的影响与γ射线的影响在性质上相同，但在数量上不同。
