electron densities and mean free path of bismuth borosilicate glass
systems over a wide range of photon energies from 1 keV to
100 GeV. Our results show that Zeff and Ne,eff parameters are dependent
on photon energy, influenced by different interactions showing
peaks (absorption edges) at low photon energy due to
dominant photoelectric effect near the M-, L- and K absorption
edge of glass compositions. The bismuth borosilicate glasses
(>5 mol%) were found to have the lowest mean free path values
and followed by serpentite, odinary, chromite, ferrite and barite
in ascending order. The results from this study indicated that the
bismuth borosilicate glass systems are good materials for gamma
rays shielding applications.
