Evaluation of irradiation parameters of enriched 124Xe target for 123I production in cyclotrons.
The production of high-purity (123)I that utilizes an isotopically enriched (124)Xe target and bombardment with 30 MeV protons, through the reactions (124)Xe (p, 2n) (123)Cs-->(123)Xe-->(123)I and (124)Xe (p, pn) (123)Xe-->(123)I, is described. The aim of this work was to improve the production parameters, such as (124)Xe load pressure, beam current, decay time and target heating to recover (123)I to obtain high-production (123)I yield at low cost.
