The synthetic B2O3As2O3 glass ceramic are prepared to investigate the physical properties and the radiation shielding capabilities with the variation of concentration of the As2O3 with 10, 20, 30, and 40%, respectively. XRD analyses are performed on the fabricated glass–ceramic and depicted the improvement of crystallinity by adding As2O3. The radiation shielding properties are studied for the B2O3As2O3 glass ceramic. The values of linear attenuation coefficient (LAC) are varied with the variation of incident photon gamma energy (23.1–103 keV). The LAC values enhanced from 12.19 cm−1–37.75 cm−1 by raising the As2O3 concentration from 10 to 40 mol% at low gamma energy (23.1 keV) for BAs10 and BAs40, respectively. Among the shielding parameters, the half–value layer, transmission factor, and radiation protection efficiency are estimated. Furthermore, the fabricated samples of glass ceramic have low manufacturing costs and good shielding features compared to the previous work. It can be concluded the B2O3As2O3 glass ceramic is appropriate to apply in X-ray or low-energy gamma-ray shielding applications.
