One group of rats was exposed to chronic gamma radiation for 300 days; other groups were given the following radioisotopes with food: /sup 90/Sr, /sup 137/Cs, /sup 144/Ce, /sup 147/Pm, /sup 45/Ca, and /sup 131/I. Urine was analyzed for deoxycytidine content 24 h later. There was an increase in deoxycytidine level in response to external radiation and radiation from radionuclides. The most marked changes occurred following external radiation; in order of diminishing effect the response to radionuclides was as follows: /sup 137/Cs, /sup 90/Sr, /sup 144/Ce, /sup 131/I, /sup 45/Ca, and /sup 147/Pm.
