Cross section calculations of medical 103Pd radioisotope using α and 3He induced reactions

Abstract

One of the most popular radioisotopes used in the prostate brachytherapy is Palladium-103 (¹⁰³Pd). The radioactive plaque is sewn onto the eye as to cover the intraocular tumor shadow with a 2-3 mm margin. These plaques are temporary and radiation is continuously delivered over 5 to 7 days. At the end of treatment, the plaque is removed from eye. In this study, production cross–section calculations of ¹⁰³Pd radionuclide used in brachytherapy produced by ¹⁰¹Ru(α,2n), ¹⁰⁰Ru(α,n), ¹⁰²Ru(³He,2n) and ¹⁰¹Ru(³He,n) reactions have been investigated in the different incident energy range up to 35 MeV. Twocomponent Exciton model and Generalized Superfluid model of the TALYS 1.6 code used to perform calculations and calculation results were compared with experimental results reported in the literature.
