Gamma radiation shielding and optical properties measurements of zinc bismuth borate glasses
P. Yasaka,Nakarin Pattanaboonmee,Hyung J. Kim,Pruittipol Limkitjaroenporn,Jakrapong Kaewkhao +4 more
TL;DR: In this paper, the mass attenuation coefficients of ZBB glasses have been measured at different energies obtained from a Compton scattering technique, and the results show a decrease of the attenuation coefficient, effective atomic number and effective electron density values with increasing of gamma-ray energies; and good agreements between experimental and theoretical values.
