Alpha radiolysis of solutions of tributyl phosphate (TBP) in several different types of diluents was studied. Yields of dibutyl phosphoric acid (as measured by plutonium-IV retention) and chloride were measured up to a dose of approximately 10 watt-hours per liter. Plutonium dissolved in the organic phase was the radiation source. The yields of dibutyl phosphoric acid (HDBP) and the Cl/sup -/ were the highest for carbon tetrachloride. The aromatic diluents give the best protection for TBP against radiolysis and also yield less Cl/sup -/. The low yield of HDBP in aromatic diluents can be explained by assuming HDBP formation by dissociation of the parent ion (TBP/sup +/). Several radiation-resistant diluents are suggested as alternatives to CCL/sub 4/ and their Pu(IV) extraction properties are presented.
