Abstract

This paper examines and presents a simple
computational Monte Carlo algorithm to determine the total, intrinsic and
geometric efficiencies of  NaI(Tl) gamma
ray detectors for gamma rays emitted by isotropic radiating (point) sources
with several energies in the range of 150-3000 keV. The code was used to compute
efficiency values for various source-to-detector distances for each studied
gamma ray energy. The comparisons with the data reported in the literature
indicated that the present algorithm is useful in efficiency calculations for
any source-detector and geometry configuration.
