To keep the accredited category for the gamma spectrometry test in our laboratory, the efficiency curves of a HPGe detector for soil sample in Marinelli geometry were determined by “efficiency transfer” principle via the ANGLE3 commercial software and Monte Carlo simulations via MCNP5 and GEANT4.

This investigation aims to compare the full energy peak efficiencies in the energy range of 46-1836 keV on a type-p coaxial HPGe and estimate the coincidence summing factor for the case of Marinelli Beaker samples used by two general Monte-Carlo simulation software MCNP and PENELOPE.

In this study, an in-house 152Eu calibration source was produced from a custom epoxy matrix with a density of r ¼ 1.14 g cm3 , which is chemically stable and durable form after its solidification. The homogeneity of 152Eu in matrix was obtained better than 98%. For a Marinelli beaker geometry, an efficiency calibration procedure was applied to a n-type, coaxial, 78.5% relative efficient HPGe detector in the energy range of 121.7e1408.0 keV by using in-house 152Eu calibration source.
