IV. CONCLUSION
In this work, the Bi2O3-SiO2 glass system was synthesized,
their radiation shielding parameters were investigated,
and comparison studies were done. The
experimentally obtained values were generally in good
agreement with the values theoretically calculated using
WinXCom. The radiation shielding properties were
found to be improved with increasing Bi2O3 concentration.
The higher Compton scattering in the bismuthsilicate
glass than in the bismuth-borate glass resulted
in a higher total mass attenuation coefficient. The better
shielding properties of the glasses, compared to some
standard shielding concrete, suggest smaller size requirements
with a strong advantage for transparency in the
visible region. The comparison studies suggested that
the Bi2O3-B2O3 glass could be a better shielding material
and could replace lead, a high-toxicity material of
globally concern.
