| Popis: | [EN] This work is focused on studying the capabilities of different Monte Carlo tools to complement the Full Energy Peak Efficiency (FEPE) calibration procedures of the Environmental Radioactivity Laboratory of the Universitat Politècnica de València, UPV. In this frame, detailed models of a High Purity Germanium detector have been implemented using MCNP6 and GEANT4. Accordingly, an inter-comparison with experimental values ensures the model validation and improves the analysis of the physics phenomena involved. The validation of the models is determined by a quantitative comparison between the simulated and the measured efficiencies over the energy range under study (59.54¿1836.01 keV). The results show discrepancies between both Monte Carlo tools for 139Ce, 88Y and 60Co as GEANT4 is able to simulate the coincidence summing effect of these radionuclides. The authors gratefully acknowledge the Catedra CSN-UPV Vicente Serradell, Spain as well as the Laboratorio de Radiactividad Ambiental (Universitat Politecnica de Valencia), Spain for the dedicated funding and resources to this research work under Grant no.
