These studies had the purpose of establishing the optimal conditions for the production of123I through the124Te (p, 2n)123I reaction, using the CV-28 Cyclotron (Emax=24 MeV for protons) at IPEN-CNEN/SP. Two different targets (TeO2 and TeO2+2% Al2O3) were irradiated in order to check their physical resistance against beam current (up to 12 μA) and length of irradiation (10 min — 2h), and to evaluate the recovery of the radioiodine produced, by a dry distillation process with a high frequency induction furnace. Later on, enriched124TeO2 (96.2%) targets were irradiated, and123I was produced routinely with a production yield of (3. 31±0.07) mCi/μAh, 1.7% of124I at EOB and radiochemically pure.
