A method for compensating for crosstalk between nuclear counters and its application to a multidetector gamma counter is described. The standardisation procedure employed measures the relative efficiency of each detector for a sample within that detector and for the same detector when the sample is located in each of the other detectors. Results with a 12-element detector system show that the stored calibration data obtained in this way can be applied successfully to correct the observed count rates for crosstalk as well as detector sensitivity differences when using gamma emitters having energies up to 1.3 MeV.
描述了一种补偿核计数器之间串扰的方法及其在多探测器伽马计数器中的应用。所采用的标准化程序测量每个探测器对该探测器内样品的相对效率,以及当样品位于其他每个探测器中时同一探测器的相对效率。一个12元素探测器系统的结果表明,以这种方式获得的存储校准数据可以成功应用于校正使用能量高达1.3 MeV的伽马发射体时观察到的串扰计数率以及探测器灵敏度差异。
