| الوصف: | In this research, gamma ray photons emitted from radioactive sources (Cs-137, Ra-226) with energies (186, 242, 295, 352, 609, 662, 1120, 1765) keV, respectively, to study some parameters, Such as the linear attenuation coefficient ( , mass attenuation coefficient ( for shield made of composite materials consisting of cement as the base material reinforced with different materials (magnesium oxide MgO , tungsten oxide WO3) nanoparticles with different reinforcement ratios (10, 30, 50) % and thickness (0.5) cm to protect against radiation. For this purpose, a sodium iodide detector activated with thallium with dimensions ( was used with an integrated measuring system, to determine the suitability of these shields for use in the field of gamma ray protection. The results showed that the values of these parameters are affected by changing the reinforcement ratios and the gamma ray energy. It was found that when increasing the reinforcement ratio of the shield led to an increase in the linear and mass attenuation coefficient, and in contrast, a decrease in the values of each occurs when the gamma ray energy of the used radioactive source is increased, especially at a concentration of 50 % and at energy (1765) Kev. |
