Evaluation of AG1-x8 to separate radionuclides in an irradiated sample

Sequential separation methods are key for rapid determination of multiple radionuclides. Seven different activation and fission products were isolated by two different sized anion exchange columns after a UTEVA/ TRU double stack. First, a 6 mL column of AG1-x8 separated Cd, Zn, Co, and Ir. The Cd recoveries were quantitative, with a decontamination factor of 10⁶ from ¹³²Te, a fission product interferent. Next, a 2 mL AG1-x8 column further separated the Fe/Ga/Te fraction from the first column. Ascorbic acid was used to control redox conditions, allowing for separation of Fe, Ga, and Te. With the use of two anion exchange columns, seven elements can be rapidly separated from a mixed activation/ fission product sample. (author)
