This study investigates the gamma radiation shielding characteristics of borosilicate glasses with varying compositions of 60B₂O₃–5Na₂O–5PbO–(30-x)SiO₂–xBaO (x = 5, 10, 15, and 20 mol%). The glasses were prepared using the conventional melt quenching technique followed by annealing. The linear attenuation coefficient (LAC) values were determined using an HPGe semiconductor detector and compared with calculated values from Phy-X software, showing good agreement. The glasses were irradiated with point sources of Am²⁴¹, Cs¹³⁷, and Co⁶⁰ to measure LAC, which was further used to compute half-value layer (HVL) and tenth-value layer (TVL). The radiation shielding efficiency (RSE) of the prepared glass materials was evaluated. Sample 10S20B exhibited higher LAC values due to its higher density and weight fraction of elements with higher atomic numbers, leading to better attenuation. The study highlights the importance of atomic number and density in enhancing shielding effectiveness.This study investigates the gamma radiation shielding characteristics of borosilicate glasses with varying compositions of 60B₂O₃–5Na₂O–5PbO–(30-x)SiO₂–xBaO (x = 5, 10, 15, and 20 mol%).
