Nowadays, glass materials are one of the possible alternatives
to concrete because they can be transparent to visible light and
their properties can be modified by composition and preparation
techniques. Boric oxide, B2O3, acts as one of the most important
glass formers and flux materials. Melts with compositions rich in
B2O3 exhibit rather high viscosity and tend to be the formation of
glasses. In crystalline form, on the other hand, borates with various
compositions are of exceptional importance due to their interesting
linear and nonlinear optical properties. The boron atom usually
coordinates with either three or four oxygen atoms forming
[BO3]3 or [BO4]5 structural units. Furthermore, these two fundamental
units can be arbitrarily combined to form different BxOy
structural groups [1]. Good reviews on radiation shielding borate
glass development have been published recently by several
authors [2–5]. These results show that the borate glass can be used
in radiation shielding materials.
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.
