Abstract
The killing efficiencies due to the decay of incorporated H(3)-thymidine, H(3)-uridine, and H(3)-histidine in E. coli 15(T-L-) have been determined. Decays from H(3)-thymidine are 2.0 times as effective in producing lethality as those from H(3)-uridine and 2.5 times as effective as those from H(3)-histidine. Therefore, it seems that the greater part of damage from H(3)-thymidine decays is due to chemical changes associated with nuclear transmutation.
摘要
已测定了大肠杆菌15（T-L-）中掺入的H（3）-胸腺嘧啶核苷、H（3）-尿嘧啶核苷和H（3）-组氨酸衰变产生的杀伤效率。H（3）-胸腺嘧啶核苷的衰变产生致死性的效率是H（3）-尿嘧啶核苷的2.0倍，是H（3）-组氨酸的2.5倍。因此，似乎H（3）-胸腺嘧啶核苷衰变造成的大部分损伤是由于与核嬗变相关的化学变化。
