Effect of PbO incorporation with different particle size on X-ray attenuation of polystyrene

Abstract

Lead oxide (PbO) bulk and nanoparticles of two different sizes (A = 78 nm and B = 54 nm) are incorporated separately into the polystyrene matrix at various concentrations (0, 10, 15, 25, and 35 %) using roll mill mixing and compressing molding techniques. The X-ray narrow-spectrum series (N-series / ISO 4037-1) is then used to investigate the radiation attenuation capability of the novel polymer composite PS/PbO, as well as the effect of varying PbO particle sizes on shielding performance. The filler dispersion and chemical elemental analysis of the synthesized composite are investigated using scanning electron microscopy and energy-dispersive X-ray spectroscopy. To determine the mass attenuation coefficients ?m, samples with various thicknesses of the synthesized composite are examined using a range of X-ray energies, and the experimental data are compared to theoretical values from NIST databases (XCOM and FFAST). The results indicate that either increasing the filler weight percentage or, decreasing the filler particle size, enhanced the attenuation parameters throughout all energies. The composite containing the smallest nanosize of PbO exhibited the maximum radiation shielding efficacy among all combinations and therefore, might be used to develop low-cost and lightweight X-ray shields.

“…Moreover, they often fall short in shielding and pose toxicity hazards as well as environmental concerns during disposal. Heavy element-reinforced polymers are a good alternative to use when making radiation shields due to their lightweight nature and the ability to form in a way that makes them useful for a variety of radiation protection applications, such as the creation of radiation-resistant clothing [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”
