Abstract
We prepared four Gd
2
O
3
doped borate glasses and investigated their physical, optical and radiation shielding features. The density of glass samples was increased linearly with the Gd
2
O
3
content. The transmission spectra of the samples show more than 85% transmittance suggesting their superior transparency in the visible region. The band gap decreases with increase in Gd
2
O
3
content. The Geant4 code was used to find the attenuation factor for the samples between 0.284 and 2.506 MeV. The results demonstrated that the transmission factor changes from 51% (corresponding to 20 mol% of Gd
2
O
3
) to 39% (for 35 mol%) at 0.284 MeV. The addition of Gd
2
O
3
affects highly the mass attenuation parameter at 0.284 and 0.347 MeV. The effective atomic numbers of the glass sample corresponding to 20 mol% of Gd
2
O
3
are in the range 12.06–18.79. The maximum tenth value layer was observed for 20 mol% of Gd
2
O

sample (15.768 cm).
