Description
The purpose of this work is to study the dosimetric parameters of the 192Ir MicroSelectron V2 High Dose Rate (HDR) Brachytherapy source. Two Monte Carlo codes, Geant4 and MCNPX, were used to simulate the dose quantities recommended by American Association of Physicists in Medicine (AAPM) Task Group 43 (TG-43). The geometry source, detectors to collect the information of interest and the water phantom were simulated. The absorbed dose and the air-kerma strength were calculated to obtain the dose rate constant. The electrons influence are evaluated for different cutoffs of energy and in the vicinity of the source where there is a lack of electronic equilibrium. (author)
