This study describes the production of the 149 Pm radioisotope from enriched neodymium oxide (Nd 2 O 3 ) targets at the Bandung TRIGA research reactor and its supporting facilities, including theoretical calculations using computer codes, target preparation, neutron activation, separation of 149 Pm radionuclide from Nd/Pm matrix, purification, and physicochemical characterization. The obtained 149 Pm was in the form of a 149 PmCl 3 solution, which remained stable at room temperature for up to 8 days after preparation with high radiochemical and radionuclide purities, thereby fulfilling the requirements for uses as a precursor in the preparation of various targeted radiopharmaceutical for cancer therapy.
