Studies have been made on the radiation chemistry of americium(VI) and americium(V) in solutions of perchloric acid and sodium perchlorate. The reduction rate is related to the dose rate and perchlorate concentration. The radiolysis products in perchlorate solutions are vigorous reducing agents for americium(VI). There is a correlation between the yield in the reduction of americium(VI) and the yield of radiolysis products. Prolonged storage of saturated weakly acid solutions of sodium perchlorate containing americium(III) and curium(III) causes the deposition of the actinoid hydroxides as well as sodium chlorate and chloride. The americium in the precipitate is partially oxidized to the pentavalent state.
