Abstract
The purpose of this study is to assess the radiation shielding performance of the lithium barium bismuth phosphate glass system from energy 0.081–1.332 MeV where the concentration (mol%) of barium and bismuth were varied yet lithium and phosphate were fixed. A few radiation shielding parameters such as linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), half value layer (HVL), and effective atomic number (Zeff) of the glass system were calculated through MCNP6 code. Enhancement of the amount of Bi2O3 on the lithium barium bismuth phosphate glass system amended the density of glass systems that’s why the value of effective atomic number was increased. Obtained results represent that the value of half value layer was 27 times higher for upsurging the incident photon energy from 0.081 M to 1.332 MeV. Moreover, at energy 1.332 MeV, the value of half value layer for sample LiBaBiP5 and LiBaBiP30 were 3.80 cm and 2.73 cm, respectively, which specifies that with the greater amount of Bi2O3 in the lithium barium bismuth phosphate glass system enhanced the radiation shielding ability. Glass system 5Li2O-5BaO-30Bi2O3-60 P2O5 showed the highest value of radiation shielding performance from energy 0.081–1.332 MeV. Eventually, it can be stated that Bi2O3 is the more suitable additives to enhance the shielding ability of glass material among the two oxides BaO, and Bi2O3.
