Liquid scintillation spectrometry is widely used for the analysis of alpha and beta emitting radionuclides. Robust calibration of liquid scintillation (LS) spectrometers is fundamental to accurate LS measurement but at the same time is time consuming and costly, particularly if a wide range of radionuclides are analysed by the laboratory. The frequency of the calibration varies in different laboratories and is based on many practical and operational factors. This work summarizes the observations regarding variations in 1220 Quantulus spectrometers efficiency calibrations performed annually using various radionuclides: H Ni, Fe, Cl, Ca, Pm, Pu, Tc for a period of 9 years and discusses the implication to calibration frequency.
液体闪烁光谱法广泛用于分析发射α和β射线的放射性核素。液体闪烁（LS）光谱仪的稳健校准是准确进行LS测量的基础，但同时也耗时且成本高昂，尤其是当实验室分析多种放射性核素时。校准频率在不同实验室有所不同，且基于许多实际和操作因素。这项工作总结了在9年时间里每年使用各种放射性核素（H、Ni、Fe、Cl、Ca、Pm、Pu、Tc）对1220 Quantulus光谱仪进行效率校准的变化情况观察结果，并讨论了其对校准频率的影响。
