Experimental determination of the HPGe spectrometer efficiency curve

A review of the calibration procedures of the semiconductor HPGe spectrometer is presented in this paper. Calibration standards were prepared using the standardized radioactive solution of the common monoenergetic radionuclides mixture and standardized multigamma 152Eu solution. The matrix materials were spiked using the activated carbon, and homogenized mechanically or by suspension in C2H5OH. Experimentally determined efficiency curves were compared with those obtained by Monte Carlo simulation.
