Özet
In the present study, we examined the rare earth sesquioxide (Y2O3, La2O3, Lu2O3) nanoparticles embedded polymethyl methacrylate and epoxy resin polymer nanocomposites as a low-density and lead-free radiation shielding material to meet the need for shielding materials that protect individuals from the harmful effects of gamma radiation. For this purpose, the linear attenuation coefficient, mass attenuation coefficient, mean free path, and half-value layer values of synthesized samples, in the form of wt. 3, 5, and 10 % rare earth sesquioxides (Y2O3, La2O3, Lu2O3) embedded polymethyl methacrylate and epoxy resin, were both calculated using WinXCOM software in the 0.001 to 100,000 MeV energy region and measured in a narrow beam transmission geometry using a NaI(Tl) scintillation detector for gamma-ray energies of 662, 1173 and 1332 keV emitted from 137Cs and 60Co radioactive sources. Y2O3, La2O3, and Lu2O3 rare earth sesquioxide nanoparticles were synthesized using thermal decomposition method and their structural features were studied by utilizing XRD and TEM measurements. The obtained results both from WinXCOM calculations and experiment were found to be in good agreement. It was found that the reinforcement with rare earth sesquioxide nanoparticles of both epoxy resin and polymethyl methacrylate and their increasing amount led to an enhancement in the radiation shielding parameters of the nanocomposite systems. The most favorable values for radiation shielding parameters were obtained for epoxy resin and polymethyl methacrylate nanocomposites containing wt. 10 % Lu2O3. It was also observed that, at 662 keV, all the shielding parameters of wt. 10 % Lu2O3 included composites exhibited more than 10 % improvement compared to nanoparticles free epoxy resin and PMMA.
