【Abstract】 HPGe γ spectrometer detection efficiencies which changes with the γ energy and the components, the densities and the volumes of environmental samples have been calculated by Monte Carlo method and have been compared with the experimental results. The comparisons show that the Monte Carlo simulation calculation is a convenient and reliable method for the efficiency calibration of the HPGe γ spectrometer.更多还原
