Heavy ion irradiation on tantalum metal target with 57 MeV 11B4+ leads to the production of no-carrier-added radioisotopes of platinum, 187,188Pt and iridium, 187,188Ir in the matrix, which have been effectively separated from the bulk target and from each other with suitable anion exchangers employing liquid-liquid extraction (LLX). Also 188,189Pt and 188,189Ir radionuclides have been produced, from their short-lived precursors 188,189Au, in 12C6+ irradiated tantalum matrix. Gamma-spectroscopy has been utilised to determine the production, extent of separation and purity of the radiotracers at different stages of the experiment.
