摘要

Within this study, pure ZnO and ZnO:Cu (10 at.% and 20 at.%) were synthesized by an efficient sol-gel method. Various physical properties were investigated using the conventional methods of energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). XRD result verified hexagonal structure of zinc oxide; however, the addition of copper, modified the main structure to some extent. The result of FESEM showed the nanosized quasi-spherical grains and the agglomeration of them. The protection factors against gamma rays, including mean free path (MFP), mass attenuation coefficients (MAC), tenth value layer (TVL), half value layer (HVL), linear attenuation coefficients (LAC) were calculated. According to these factors, it can be concluded that the use of ZnO and ZnO–Cu (10 at.% and 20 at.%) as a gamma ray protector can be useful. In addition to the experimental examination, simulation with GEANT4 simulation code was also used to examine the shielding parameters.
