Abstract: Hetrometal oxides of (1 - x)Al2O3/xPbO2(NPs) nanoparticles with different PbO2content(x = 0, 0.3, 0.4, 0.5, 0.6 and 0.7) have been prepared by irradiation method. The NPs powder hasbeen checked by X-ray diffraction (XRD). XRD measurements affirmed the presence of bothpure NPs and nanocomposites of (1 - x)Al2O3/xPbO2NPs with different PbO2contents. Thecalculated structural parameters which using the experimental result of XRD charts to givea complete image of these measurements. Moreover, the results using FLUKA code showedthat the values attenuation coefficient (_m), high effective atomic number (Zeff) and neu-tron shielding parameters increase as the lead dioxide increase in the Al2O3/PbO2samples.While the values of half-value layer (HVL) and mean free path (MFP) decrease with increas-ing PbO2content. The investigated shielding features of the chosen Al2O3/PbO2would beadvantageous for exposure control. © 2020 The Authors.
