The linear attenuation coefficient (μ), mass attenuation coefficient (μ/Ã?â??Ã?â?¬) were calculated for Zn element. The values of gamma ray mass attenuation coefficient were obtained using a NaI (Tl) detector using scientillation counter with radioactive gamma ray sources having energy 0.36,0.511,0.662,1.17,1.28 and 1.33 keV. The experimentally obtained values of μ andμ/Ã?â??Ã?â?¬ thus obtained are found to be in good agreement with the theory. Mass attenuation coefficient and linear attenuation coefficient of gamma rays photons of energy for 360- 1330 KeV in zinc have been determined experimentally through photon –transmission measurement performed under narrow collimated beam counting geometry with scintillation spectrometer as a photon detector. The Mass attenuation coefficient and linear attenuation coefficient values reported in this work are found to be in good agreement with the values computed theoretically. Mass attenuation coefficient and linear attenuation coefficient represent a subject of considerable interest and importance, since it is required in solving various problems in a radiation physic and radiation dosimetry and of interest for industrial, biological, agriculture and medial studies.
