[en] These studies had the purpose of establishing the optimal conditions for the production of ¹²³I through the ¹²⁴Te (p,2n) ¹²³I reaction, using the CV-28 Cyclotron (E_max = 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 - 2 h), and to evaluate the recovery of the radioiodine produced, by a dry distillation process with a high frequency induction furnace. Later on, enriched ¹²⁴TeO₂ (96.2%) targets were irradiated and ¹²³I was produced routinely with a production yield of (3.31 ± 0.07) mCi/μAh, 1.7% of ¹²⁴I at EOB and radiochemically pure.
