本文分析了闪烁计数器电压脉冲幅度分布的各种原因。一个一般的表达式推导出的方差的分布在由磷光体发射的光子的数量的变化，在收集效率的变化，在不同的点发射的光子在磷光体和光电倍增管的统计。还考虑了荧光粉缺陷、光阴极和倍增极结构的非均匀响应、光阴极和卫星脉冲的电子发射等因素的影响。开发的方程的使用说明了一些常见的安排的详细讨论。
The various causes of the distribution in magnitude of the voltage pulses from the scintillation counter are analysed. A general expression is derived for the variance of this distribution in terms of variations in the number of photons emitted by the phosphor, variations in collection efficiency for photons emitted at different points within the phosphor and photomultiplier statistics. The effects of phosphor imperfections, non-uniform response of photocathode and dynode structures, thermionic emission of electrons from the photocathode and satellite pulses are also considered. The use of the equations developed is illustrated by detailed discussion of some commonly occurring arrangements.
