Radiation Shielding Enhancement of Polyester Adding Artificial Marble Materials and WO3 Nanoparticles

The radiation shielding abilities of waste marbles with different concentrations WO3 (tungsten oxide) nanoparticles were investigated. Four prepared 0, 0.05, 0.1, and 0.2 nanoparticles. study aims to investigate the effect concentration, density, particle size marble samples. linear attenuation coefficient (LAC) S1 sample, sample no WO3, was determined theoretically experimentally, results demonstrated that they close enough together adequately determine LAC other Additionally, samples nano-WO3, rather than micro-WO3, found have a greater LAC, showing decreasing improves their ability. Samples content also had higher values. evaluated at wide energy range (0.015–15 MeV) examine properties for applications, an inverse trend between observed. protection efficiency (RPE) absorb almost all incoming photons low energies. As increases, naturally drops, as are able penetrate through them ease. High dependence when calculating half-value layers (HVL) When comparing mean free paths (MFP) marbles, relationship Furthermore, nano-WO3 smaller MFP those meaning Zeff micro-WO3 values followed three distinctive trends depending on photons.
