New Analytical Formulae to Calibrate Well-type Scintillation Detectors Efficiency

Abstract

Abbas MI, Ibrahim OA, Ibrahim T, and Sakr M,

Direct Mathematical calculations for the absolute efficiency of well-type gamma ray scintillation crystals are described. Calculated detection efficiencies are drawn for two commonly used well crystals. Comparisons are made between present works and published Monte Carlo values. The present approach proved quite success in predicting the efficiency of well type detectors providing only the geometry and materials of the system formed of source, detector and shielding as well as the energy of the emitted photons.
