Bismuth (Bi) and barium (Ba) are playing on important role in
radiation glass shielding and replacing lead (Pb) due to environmental
toxicity of Pb and protectionism in world economy. In this
work, we have measure the total mass attenuation coefficients of
the candidate materials which used for radiation shielding glass
development such as Bi2O3 and BaO in borate glass system at
662 keV, and compare with PbO in same glass system. Moreover,
shielding parameters such as half value layer (HVL) and effective
atomic numbers are also determined and compare with ordinary
concrete and commercial window for useful of radiation shielding
glass design, and investigate influence of Bi2O3 and BaO content in
xRmOn: (100 x)B2O3 (RmOn = Bi2O3 and BaO and where
x = 30 6 x 6 70% by weight) glass system.
