METHOD FOR DETERMINING THE PHOTOPEAK EFFICIENCY OF SCINTILLATION COUNTERS

;
A technique for determining the photopeak efficiency of certain scintillation counters for gamma rays, by detecting coincident radiations with a single Nal(Tl) counter, is described. The method is based on the fact that, for coincident radiation, a detecting system presenting 4 pi steradians to the source has an efficiency epsilon ( gamma /sub 1/) for detecting a quantum gamma /sub 1/ and an efficiency epsilon ( gamma /sub 1/) epsilon ( gamma /sub 2/) for detecting both quanta simultaneously.
