摘要
本文评价了Aloka商品液闪仪效率示踪法dpm校正的效果。轻,中度猝灭校正效果理想,具有简便、实用和适用性广泛的特点。严重化学和颜色猝灭样品的校正结果分别随猝灭增加而向增大和减小的方向偏离,形成喇叭状曲线,文中对这一现象给出初步解释。
Quenching corrected results by efficiency tracing technique in newest commodity liquid scintillation counter(Aloka Model LSC-3500)were evaluated. The corrected dpm errors are less than 3% and 4% for light and medial quenching samples respectively. This quenching correction method possesses simplicity, practicality and extensive suitability. The corrected dpm values will increase and decrease accomapanying with increasing quenching degree for chemical and colour quenching, so that suona type error curve can be obtained, The interpretation for the phenomenon was given in the paper.
