Abstract
The concept of representing the detector volume by a virtual point detector in order to facilitate efficiency evaluations was proposed in the past for non-absorbing media. The validity of the model was expanded also to absorbing media present between the detector and a point source in front of it. Empirical values were determined based on experiments with aluminum, copper, iron and lead.
摘要
过去曾提出通过虚拟点探测器来表示探测器体积以促进效率评估的概念，该概念适用于非吸收性介质。该模型的有效性也扩展到探测器与其前方点源之间存在的吸收性介质。基于对铝、铜、铁和铅的实验确定了经验值。
