摘要：

An efficient Monte Carlo program for calculation of total intrinsic efficiency, peak-to-total ratio and source intrinsic efficiency of bare right-circular cylindrical NaI(Tl) detectors from an arbitrarily located isotropic point source emitting photons of energy 1 MeV or below is outlined. Total variance reduction based on physical principles is used throughout to insure that each proton history is successful in order to minimize computer time. Results show close agreement with other Monte Carlo calculations for sources located along the detector axis and with experiments for sources located off-axis. © 1978.
