摘要

本文介绍了一个计算放置在形状良好的伽玛射线探测器顶部的圆柱形样品衰减系数的数学公式。该公式依赖于光子通过样品的平均路径长度和有效立体角的计算。利用引入的公式得到的结果与NIST XCOM数据库进行了比较，并与两个不同尺寸的探测器和两个不同位置的源的实验结果进行了比较。两者之间有显著的一致性，证明了公式的有效性。

Mathematical Formula to Calculate the Attenuation Coefficients for Any Complex Sample: Experimental Study

This work introduces a mathematical formula to calculate the attenuation coefficient of a cylindrical sample placed on the top of a well-shaped gamma-ray detector. The formula depends on calculations of the average path length of the photon through a sample and the effective solid angle. The obtained results using the introduced formula are compared with the NIST XCOM database and also compared with the experimental work using two different-sized detectors and sources located in two different positions. A remarkable agreement between both was observed, which proves the validity of this formula.
