## 10 Effect of Sb\({}_{2}\)O\({}_{3}\) Modifier  
Sb\({}_{2}\)O\({}_{3}\) when added to glass enhances its structural, thermal, and optical properties [57]. Table 11 summarizes the mass attenuation coefficients of the studied glass with different fractions of Sb\({}_{2}\)O\({}_{3}\) at a wide photon energy range from 10 keV to 20 MeV. On the other hand, Table 12 summarizes the neutron effective removal cross sections of the studied glass with different fractions of Sb\({}_{2}\)O\({}_{3}\). The photon-shielding capabilities of glass have been enhanced with the addition of the Sb\({}_{2}\)O\({}_{3}\) modifier while the neutron-shielding capabilities are decreased.
