Abstract

X-IRRADIATION causes the degradation of DNA in bacteria exposed to medium and high doses of radiation1,2. Low doses have no visible effect on the synthesis of DNA, the degradative process starting only after 3–4 kr. However, we observed that there exists a saturation in the effect since doses of 24 and 32 kr. cause almost the same degree of degradation of DNA as do the lower doses. Stuy3 has found the same effect with irradiated bacteria which were, however, starved after irradiation.
