摘要: Abstract In this study, the radiation mass attenuation coefficients of different bismuth-borate glass samples as shielding materials are calculated at 356, 662, 1173 and 1332 keV photon energies by using general purpose Monte Carlo code MCNPX (version 2.4.0). The obtained numerical results agreed well with previous experimental, theoretical standard XCOM data. validated simulation geometry has been used then to investigate properties B2O3–Bi2O3–SiO2–TeO2 system. parameters such coefficients, effective atomic number, mean free path have variation in these was discussed terms both energy Bi2O3 concentration. maximum values number were found for Bbi7 sample. glasses compared half value layer some commercially-available developed SCHOTT company. Also, present those steel-magnetite concrete. comparison reveals that system can be applications.
