Comparative study of gamma ray shielding and some properties of PbO–SiO2–Al2O3 and Bi2O3–SiO2–Al2O3 glass systems

New gadolinium based glasses for gamma-rays shielding materials

“…In the composite materials, the interactions of photon with these materials are related to the obtained Z eff values and photon energies. Similar results have been published for shielding glass materials (Manohara et al, 2010;Kirdsiri et al, 2010;Singh et al, 2002Singh et al, , 2004Singh et al, , 2005Singh et al, , 2008Singh et al, , 2014Kurudirek et al, 2010;Chanthima et al, 2012;Yasaka et al, 2014;Kirdsiri et al, 2009). It might be concluded that the Z eff depends on the photon energy.…”

“…Because of environmental toxicity of lead (Pb) and protectionism in world economy, the development of lead-free radiation protecting glasses are important. Several investigations Singh et al, 2002Singh et al, , 2004Singh et al, , 2005Singh et al, , 2008Singh et al, , 2014 have been on Pb-free glass samples those could be use as a radiation shielding material. Manohara et al (2010), reported effective atomic numbers and related parameters for CaO-SrO-B 2 O 3 , PbO-B 2 O 3 , Bi 2 O 3 -B 2 O 3 , and PbO-Bi 2 O 3 -B 2 O 3 glasses at photon energies from 1 keV to 1 GeV.…”

OPTICAL PROPERTIES OF [(TeO2)0.7 (B2O3)0.3]100-x (BaO) x GLASS SYSTEM

“…It was found [7] that barium-borate glasses have good value in mass attenuation coefficient and effective atomic number which make good radiation shielding materials. (B 2 O 3 TeO 2 ) glasses have been shown progressive changes in both the boron and tellurium coordination with the addition of other ions [8,9]. The aim of the present work is to study, the physical and optical properties of [(TeO 2 ) 0.7 (B 2 O 3 ) 0.3 ] 100-x (BaO) x (x =50,60,70) in order to show the effect of chemical modifier such as BaO on physical and optical properties when added to (B 2 O 3 TeO 2 ) glasses.…”
