The full-energy-peak efficiency calibration for a HPGe detector has been constructed in the γ-ray energy range from Eγ = 50–1500 keV, using 8 standard point sources of gamma radiation, namely Na-22, Co-57, Co-60, Cd-109, Ba-133, Cs-137, Eu-152, Am-241. The measuring system equipped with sample holder to investigate the source-to-detector distance (x) dependence for 5–24.5 cm range. The universal empirical formula was proposed to calculate the detector efficiency depending on energy Eγ and distance (x). The formula was tested for several measurements and broadened energy rage up to 3 MeV.
