Impact of BiO on prepared nano (SiO-NaO-CaO-BO) glass as radiation shielding material.

Melt quenching technique was used to create Bismuth Boro-Silicate nano glasses with compositions of 45SiO-10CaO- 25NaO- xBiO- (20-x) BO (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.
