摘要
文章报导了关于圆柱体源的γ谱分析的不同密度源的自吸收校正函数模型。该模型统一反映了γ射线能量、装样密度对自吸收校正函数的影响,从而为γ谱分析的测量效率的刻度找到了一条捷径。
The paper reports a self-absorption correction function used for cylindricalsamples with different density in the Gamma-ray spectrum analysis. The effectsof the Gamma-ray energy and sample density on the self-absorption are unitized inthe function model, and so a shortcut for detection efficiency calibration in theGamma-ray spectrum analysis is found.
