摘要：
This paper describes a method of calibrating the efficiency of a Ge γ-ray spectrometer. 226Ra and 232Th were selected to produce the soil calibration source, and then several γ-rays with high emission probabilities in 226Ra’s decay products and 232Th’s decay products, along with 2754 keV γ-rays of 24Na in the primary coolant sample of PWR, were employed to perform efficiency calibration. After self-absorption correction and true coincidence summing correction, we obtained the efficiency curve of a Φ70  ×  30 mm aqueous calibration source over the high energy range (1120–2754 keV).
