Sequential separation of carrier free radioisotopes of rhodium, silver and cadmium produced in α-particle activated palladium by TOA

Carrier free radioisotopes of rhodium, silver and cadmium, 101,105,106mRh, 103,104,105,106,110m,112Ag and 104,105,107,109,111mCd, respectively, were produced simultaneously by α-particle activation of metallic palladium. The radioisotopes produced were separated by LLX using TOA as a liquid anion exchanger. The presence of the various radionuclides in the activated target matrix and their purity at various stages of separation were verified by taking recourse to γ-ray spectrometry.
