Abstract
Exposure to high levels of ionizing radiation poses serious health risks, especially for workers in medical, industrial, and nuclear environments. Traditional shielding materials like lead have significant drawbacks, including toxicity and environmental concerns. This study fo-cuses on developing lead-free heavy metal oxide glass materials that offer effective X-ray and gamma-ray attenuation while maintaining transparency, structural durability, and cost efficiency. In this work, the radiation shielding parameters of the glass system, with the chemical composition xBi 2 O 3 − (55-x)B 2 O 3 − 15BaO − 10ZnO − 18SiO 2 − 2Nd 2 O 3 (where x =15, 20, 25, 30, and 35 mol%). was investigated. The radiation shielding properties were investigated through simulations using XCOM software over a photon energy range of 0.03 to 0.3 MeV. The results show that increasing Bi 2 O 3 content significantly increases the mass attenuation coefficient (MAC), indicating better shielding performance compared to similar glass compositions reported in the literature.
