Radiation Shielding Properties of recycled waste glass color doped powder cement pastes

In the present study, the gamma-ray shielding performance of cement (CEM), green, brown, and transparent glass materials was systematically investigated over the photon energy range of 0.015–15 MeV. Key radiation attenuation parameters including mean free path (MFP), half-value layer (HVL), tenth-value layer (TVL), effective atomic number (Zeff), and radiation protection efficiency (R) were evaluated using the Phy-X/PSD computational platform. The obtained results demonstrate a strong dependence of shielding parameters on photon energy, governed by dominant interaction mechanisms such as photoelectric absorption, Compton scattering, and pair production. Cement exhibited the lowest MFP, HVL, and TVL values across the studied energy range, indicating superior shielding efficiency, while colored glass samples showed competitive attenuation performance, particularly at intermediate photon energies. These findings suggest that cement and glass-based materials can serve as effective and practical alternatives for gamma-ray shielding applications.
