Alternative methods for the production of carrier-free (66,67)Ga

Heavy ion activation of natural cobalt foil with 52 MeV 11B4+ and 73 MeV 12C6+ results in the formation of carrier-free (66,67)Ge and (66,67)As radionuclides, respectively, along with their corresponding decay products, (66,67)Ga in the matrix. The carrier free gallium radionuclides have been separated from the bulk target matrix cobalt by employing liquid-liquid extraction method using TOA as liquid anion exchanger.
