Efficiency calibration and coincidence summing correction for a 4π NaI(Tl) detector array

Abstract

Efficiency calibration and coincidence summing correction were performed for an array of NaI(Tl) detectors developed for in vivo neutron activation analysis. The detector array consisted of eight large NaI(Tl)s with square cross-section and the enclosing geometry of the detection produced both extremely high efficiency and a severe coincidence summing effect. The efficiency was calibrated mainly by Monte Carlo simulation with the EGS4 code. In …
