Investigation of the Production of Medical Ir-192 Used in Cancer Therapy via Particle Accelerator

Abstract

To investigate the production of medical Ir-192 radionuclide used in brachytherapy on Os targets in the energy range of E particle = 100 ! 1 MeV, we calculated the cross-section results for charged particle-induced reactions. The calculation was done via TALYS code and simulated activity and yield of product of each reaction process in the irradiation time of 1 h with constant beam current of 1 μ A. The calculated results were compared with experimental data in the literature. Moreover, based on the calculated cross-section data and the mass stopping powers obtained from X-PMSP program, the integral yield results of all the reaction processes to produce Ir-192 on Os targets were presented as a function of incident particle energy. The obtained results were discussed to recommend appropriate reaction processes and targets for the production of Ir-192.
