Impact of Bi₂O₃ on prepared nano (SiO₂-Na₂O-CaO-B₂O₃) glass as radiation shielding material

Melt quenching technique was used to create Bismuth Boro-Silicate nano glasses with compositions of 45SiO₂-10CaO- 25Na₂O- xBi₂O₃- (20-x) B₂O₃ (where x is 0, 5, 10, 15, and 20 mol %). Standard point sources AM-241, Ba-133, Co-60, Cs-137, and Eu-152 were used in the radiation experiment to evaluate the attenuation coefficients spanning the energy range of 59.51 keV to 1048.01 keV. The findings show that adding Bi₂O₃ in place of B₂O₃ increases the following: radiation protection efficiency (RPE%), transmission factor (TF%), absorption buildup factor values (ABF), exposure buildup factor values (EBF), mass attenuation coefficients (MACs), linear attenuation coefficients (LACs), and radiation protection efficiency (RPE%). In comparison to lead glass, these findings demonstrate the potential of nano Bismuth Boro-Silicate glass as a radiation shielding material.
