Abstract

The radiation parameters of barite sodium silicoborate glass (BaSO₄:Na₂O:SiO₂:B₂O₃) with different concentration of barite (BaSO₄) were studied. The mass attenuation coefficient (μ/ρ), effective atomic number (Z_eff) effective electron densities (N_e,eff) and half value layer (HVL) have been calculated by theoretical approach using WinXCom program in the energy range of 1 keV to 100 GeV. The results of these parameters are show graphically for total and partial photon interaction. It was found that the Z_eff show discontinuous jumps related to absorption edges and dominance photoelectric effect at low energies, pair production have two types which are nuclear and electron field and its slightly increased with increasing photon energies. The variation of N_e_,eff was related to the value of Z_eff. The half value layer (HVL) of glasses were compared with commercial window and some standard shielding concretes which observed that the value of 20 mol% BaSO₄ has lower than commercial window, ordinary and hematite-serpentine concretes. These results showed that glass sample is promising radiation shielding materials.
