Abstract
A method for producing a radionuclide is provided that produces molybdenum trioxide 99 (Mo-99.O) and technetium oxide 99m (Tc-99m.O) by emitting an electron beam accelerated by an electron linear accelerator to a molybdenum trioxide 100 (Mo-100.O) powder sample, and which separates and purifies technetium oxide 99m from both the molybdenum trioxide 99 and the technetium oxide 99m by using a radionuclide separation/purification unit. The method for producing a radionuclide supplies temperature-regulated gas to the molybdenum trioxide 100 powder sample during an irradiation period during which the electron beam is emitted to the molybdenum trioxide 100 powder sample.
