Enhanced Gamma-Ray Shielding with Silver-Doped Glass: A Promising Solution

What is it about?

This study investigated the gamma-ray shielding properties of As2O3 glass ceramics doped with varying concentrations of Ag2O within chalcogenide oxides SeO2 and TeO2. The methodology involved simulations using the Monte Carlo N-Particle (MCNP) code and theoretical validation with the Phy-X/PSD software to assess the influence of Ag2O on the attenuation characteristics of these glass systems. Five glass compositions were analyzed, with ATSAg0.50, containing 0.50 mol% Ag2O, demonstrating superior density and attenuation coefficients, indicating enhanced shielding capabilities. Detailed assessments included linear and mass attenuation coefficients, half-value layer (HVL), mean free path (MFP), and transmission factors (TFs) across a wide photon energy spectrum. ATSAg0.50 exhibited the lowest TFs and shortest MFP, highlighting its potential as an efficient gamma-ray shield. The study concluded that ATSAg0.50 is a promising candidate for gamma-ray shielding applications, effectively balancing material efficiency with performance.
