ABSTRACT:
Charged-particles in the 45-15 MeV energy range incident upon isotopically enriched xenon-124 gas in a gas-target assembly cause nuclear reactions which yield radioactive xenon-123. The xenon-123, decaying either in the target assembly or in a decay vessel removed from the target assembly, yields iodine-123 with very low levels of radioactive contaminants.
