摘要：

The detection efficiency of a broad-energy germanium detector was determined empirically and compared to predictions by the Monte-Carlo software GEANT4 and FLUKA. The considered source geometries were point-like, filter paper and a water beaker. Calculations were performed in the photon energy range of 30-1836 keV. Simulated detection efficiencies obtained from both Monte-Carlo software were found to be in a good agreement (typically < 5%) with experimental results for the considered source geometries. A comparison between the detection efficiencies obtained with GEANT4 and FLUKA codes exhibited a good agreement with a robust average of approximately 1%.
