The half value layers (HVL) of all glass samples based on the
present work are shown in Fig. 6 with some standard radiation
shielding concretes and commercial window. It was found that
though out the concentration of the Bi2O3 and PbO studied, the
glasses exhibited better shielding properties than commercial window,
ferrite and barite concrete. This reflects the advantage of
using bismuth and lead component in radiation shielding glass.
In the case of the BaO glass, it has better HVL values than ordinary
concrete and commercial window, but showed poorer values when
compare to barite and ferrite concrete. This indicates that the BaO
glass might be used in place of ordinary concrete and commercial
window to shield gamma-rays at this energy.
