Therefore whereas a dental x-ray room may require a. nominal shielding of about 1.5mm lead for the direct beam and. about 0.7mm lead for the scattered field, a diagnostic x-ray. room may require a nominal shielding of about 3mm and 1.5mm. for the direct beam and scattered field respectively.
Lead is a Block P, Period 6 element, while oxygen is a Block P, Period 2 element. Lead is a soft and malleable metal. The morphology of lead oxide nanoparticles is red or yellow crystalline solids. Lead oxide nanoparticles are graded as toxic and dangerous for the environment. The chemical properties of lead oxide nanoparticles are outlined in the following table. The physical properties of lead oxide nanoparticles are given in the following table. The thermal properties of lead oxide nanoparticles are provided in the table below.
