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 Bi2O3 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 Bi2O3 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 Bi2O3 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 Bi2O3 mol % samples, respectively, (c) 2024 The Electrochemical Society ("ECS").
