Abstract
In this project the variation of the intrinsic efficiency of the Na I (Tl) detector against the source detector distance has been calculated for different gamma ray energy of 0.1, 0.2, 0.4, 0.6 1, 5, 7 and 10MeV and taking in to account various source to detector distance, ranging from 0 to 10 cm. The intrinsic efficiency depends not only on energy of photons but also on the geometry configuration of source and detector and source to detector distances. The intrinsic efficiency variation can be analyzed by the mean chord path length of the photon in the detector and the linear attenuation coefficient of photon in the detector.
