Radiation damage to 5 vol% alkyl amine-kerosene modified with lauryl alcohol was studied through the behavior changes of uranium and some fission products in extraction, scrubbing, and stripping in the nitrate system. Tested were three tertiary and four secondary amines, i.e., trioctyl amine, N-benzyl dilauryl amine, N-cyclohexyl dilauryl amine, N-cyclohexyl lauryl amine, dilauryl amine, Amberlite LA-1, and LA-2. They were irradiated to the extent of 10/sup 8/ r by Co/sup 60/ gamma ray, prior to extraction. Little changes in the extraction, scrubbing, and stripping behavior were observed in all amines tested, except N-cyclohexyl lauryl amine. The phase separation time after the mixing in ex traction varied very little with radiation dosage. Ncyclohexyl lauryl amine formed an emulsion even without irradiation. In the radiation resistance, amines are superior to tributyl phosphate, although the separation of uranium from fission products with amines is not as perfect as with tributyl phosphate in the nitrate system.
