Radiation Shielding Properties of B₂O₃-ZnO-BaO-TiO₂-Bi₂O₃ Glass System: A Study on Eu-152 Radiation

The focus of this investigation is the evaluation of the B₂O₃-ZnO-BaO-TiO₂-Bi₂O₃ glasses’ radiation shielding properties within the 0.122–0.867 MeV energy range. A 0.75 cm thickness glass’s radiation protection efficiency (RPE) was evaluated, revealing that the higher Bi₂O₃ content glass exhibits superior RPE compared to the other samples. The RPE of the glasses at 0.245 MeV are equal to 73 and 83% for the 18 and 30 Bi 2 O 3 mol % glasses, respectively. The transmission factor (TF) results demonstrated that increased glass thickness leads to a reduction in TF values, leading to higher attenuation. The TF values at 0.296 MeV are 40, 22, and 14% for 0.75, 1.25 and 1.6 cm thickness, respectively. It was revealed that the higher Bi 2 O 3 content glass has the lowest TF values. The TF values at 0.245 MeV are 27, 23, 19 and 17% for the 18, 22, 26, and 30 Bi 2 O 3 mol % samples, respectively. At 0.245 MeV, the effective atomic number values are 40.32, 42.45, 48.58, and 48.81 for the 16, 22, 26, and 30 Bi 2 O 3 mol % samples, respectively,
