The purpose of this study is to determine the dosimetric parameters of a new 125I brachytherapy seed model, using Monte Carlo (MC) simulations according to the TG-43U1 recommendation. The Monte Carlo simulated dosimetric parameters of this sourse have been provided with MCNPX v.2.6 code. The source contains a cylindrical Ag+Al2O3 marker which is located at the center of the seed and onto which...
