| 摘 要： | 本文提出了采用标准线源代替标准体源对装置进行效率校准的等效活度校准方法。利用蒙特卡罗模拟方法，研究了不同介质密度和特征γ射线能量对线源校准位置的影响。测量实验结果与模拟计算结果吻合，证实了这种方法是一种介于常规效率校准与无源效率校准两种方法之间的等效校准技术。

| Abstract: | In this paper, an equivalent calibration technique using line-like standard radiation source was studied, which is expected to substitute the efficiency calibration of volume standard radiation source. The effects of density of matrix and energy of gamma-ray on the location of line calibration source were studied. The consistency between the measurement and simulation shows the effectiveness of the equivalent calibration technique. |
