This study investigates the gamma radiation shielding properties of borosilicate glasses containing BaO as a substitute for SiO₂. Four glasses with compositions 60B₂O₃-5Na₂O-5PbO-(30-x)SiO₂-xBaO (x=5, 10, 15, 20 mol%) were prepared using the conventional melt quenching technique followed by annealing. The linear attenuation coefficient (LAC) was measured using an HPGe detector and compared with values calculated by Phy-X software. The samples were irradiated with point sources of Am²⁴¹, Cs¹³⁷, and Co⁶⁰. The LAC data were used to calculate the half-value layer (HVL) and tenth-value layer (TVL). Radiation shielding efficiency (RSE) was also evaluated. The sample with 20 mol% BaO (10S20B) showed the highest LAC due to its high density and atomic number content. The study highlights the importance of atomic number and density in gamma shielding. Gamma radiation, originating from nuclear processes, is widely used in medical applications but poses health risks. Shielding materials, such as concrete, steel, and lead, are used to protect against gamma rays. However, new materials like BaO, PbO, B₂O₃, Na₂O, and SiO₂ are being explored for their shielding properties. BaO enhances shielding by increasing material density. The study emphasizes the need for effective gamma shielding to protect healthcare workers and patients. The research aims to evaluate the shielding ability of borosilicate glasses with varying BaO content. The results show that increasing BaO content improves shielding efficiency. The study contributes to the development of safer medical technologies by improving gamma radiation shielding protocols.This study investigates the gamma radiation shielding properties of borosilicate glasses containing BaO as a substitute for SiO₂.
