Abstract

Our goal in this research is to investigate the effect ofconcrete incorporated with nanoparticles of lead oxide inpowder form by different percentages on Gamma-ray shieldingcharacteristics. The lead oxide nanostructure was synthesizedthrough the reaction of citric acid (C6H7O8.H2O) solution andlead acetate (Pb (C2H3O2)) solution as stabilizer and precursor,respectively. In this synthesis, the prepared lead oxidenanostructure was characterized by X-Ray Diffraction (XRD)and Scanning Electron Microscopy (SEM) techniques. Theprepared PbO consists of the crystallites about 50 nm. Theconcrete samples were prepared according to the localstandards of building materials and doped with PbO nanopowders by different percentages, 0%, 5%and 10% (by weight)by replacing cement and keeping constant w/c ratio. Moreover,commercial PbO bulk powder additive was used to check theeffect of particle size on concrete attenuation properties. The γ-rays attenuation coefficients were measured as a function of theadditive percentage of nanoparticles of lead oxides and using γ-ray point source,126Ra with different energies in the range(0.295- 1.73) MeV. The results were compared with that fornormal concrete incorporated with the same percentage of bulklead oxide. It was found that the γ-ray attenuation coefficientfor concrete doped with nanoparticles of PbO was slightlyimproved.
