摘要
本文阐述了GM计数管的两种死时间概念,分析了它们对辐射测量的影响,并给出了输出计数率与照射量率和两种死时间的关系式。
Two conceptions on dead time of GM counter are explained in this paper. The effect on radioactive measurement is analyzed and the relations of counting rate or exposure rate to two dead time are given. Over 5 decades linear range has been realized by a optimum output circuit and a lineari zing technique including software and hardware.
