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

Heavy ion activation of natural cobalt foil with 52 MeV 11B4+ and 73 MeV 12C6+ results in the formation of carrier-free 66,67Ge and 66,67As radionuclides, respectively, along with their corresponding decay products, 66,67Ga 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.
