It was shown that during prolong intense ..cap alpha.. irradiation of concentrated weakly acid solutions of sodium perchlorate, containing curium(III), americium(III), and plutonium(IV), two types of precipitates are formed: amorphous and crystalline. It was established that in this case there is a substantial decrease in the acidity of the solution. It was found that the crystalline precipitate represents sodium chloride, while the amorphous precipitate consists of hydroxides of the actinides. In the amorphous precipitate neptunium is in the hexavalent state and americium in the tri- and pentavalent states.
