Comparative Killing Efficiencies for Decays of Tritiated Compounds Incorporated into E. coli.
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.
