The investigation of glass for radiation shielding material has been more intense. It occurs because the development of crystal is complicated, inflexible to shape and high-cost production. Meanwhile, glass possesses high refractive index, transparency, easy to fabricate and low-cost production. The glasses development were manufactured by melt and quenching method. The radiation shielding properties were measured by Compton scattering instrument. The addition of metal oxides such as Bi 2 O 3 , PbO, and BaO in silicate glass improved the density and effective atomic number of the glass sample. Meanwhile, the addition of oxyfluoride in borate glass decreased the mass attenuation coefficient of glass. Both experimental data of effective atomic number and mass attenuation coefficient of glass were compared by theoretical data. The theoretical data was calculated by WinXCom program. The highest of absorption spectra occurred due to the addition of oxyfluoride in glass system. All results showed that glass was a suitable candidate for radiation shielding material. The oxyfluoride glass possessed the more potential for radiation shielding material among glass samples.
