Microprocessor crosstalk correction in multiple-detector gamma counters

Abstract

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.
