Abstract

Some glass samples having the molecular composition [(70-X) mol % B2O3 + 10 mol % BaO + 20 mol % Na2O + X mol % As2O3 where X = 0, 5, 10, 15 and 20] have been prepared by melting at 1200 ºc for two hours. They were thoroughly investigated from the gamma – ray attenuation parameters by applying both MCNP and Win X-Com programs. The applied gamma-ray energies were 661.7 keV (emitted from 137Cs) and 1173.2 & 1332.5 keV (emitted from 60Co). It was found that as As2O3 was gradually increased, the linear attenuation coefficients increased gradually, while the half value layer and mean free Path decreased. On the other hand, both linear and mass attenuation coefficients decreased and the half value layer and mean free Path increased as the energy of the incident γ-ray photon increased. Finally, it can be concluded that these glasses can be used as good γ-ray attenuators especially at low gamma-ray energies.
