Comparative Study of Radiation Shielding Parameters for Bismuth Borate Glasses

Abstract

Melt and quench technique was used for the preparation of glassy samples of the composition x Bi 2 O 3 -(1-x) B 2 O 3 where x= .05 to .040. XCOM computer program is used for the evaluation of gamma-ray shielding parameters of the prepared glass samples. Further the values of mass attenuation coefficients, effective atomic number and half value layer for the glassy samples have been calculated in the energy range from 1KeV to 100GeV. Rigidity of the glass samples have been analyzed by molar volume of the prepared glass samples.

Physical, structural, optical and gamma‐ray shielding properties of Na2O‐CdO‐Bi2O3‐B2O3 glasses

“…It can be inferred that an expansion in the glass network was occurred with the addition of bismuth oxide, which may be due to increase nonbridging oxygen bonds and larger ionic radius of Bi 3+ (1.03 Ǻ) compared to B 3+ (0.27 Ǻ). This result is consistent with previous related studies 41,42 . This explanation was reinforced when the values of oxygen packing density reduced (126.919 to 77.806 g.atom.l −1 ) with increasing of Bi 2 O 3 content.…”

“…This result is consistent with previous related studies. 41,42 This explanation was reinforced when the values of oxygen packing density reduced (126.919 to 77.806 g.atom.l −1 ) with increasing of Bi 2 O 3 content. Regarding the optical basicity, an inversely proportion was reported with increasing of bismuth oxide bond strength.…”

The Effect of WO3-Doped Soda Lime Silica SLS Waste Glass to Develop Lead-Free Glass as a Shielding Material against Radiation

“…Concrete is efficient and cheap, and can be easily shaped into any desired design [4]. However, there are some limitations related to concrete, such as its opacity, preventing visible light from passing through, and its mechanical strength being reduced when exposed to radiation for a longer period of time [5][6][7][8]. Glass is a type of radiation shielding material that can be an alternative to concrete for protection from radiation risks due to its remarkable chemical and physical properties, such as excellent optical transparency to visible light, simplicity of manufacturing, nontoxicity , low cost, and its physical characteristics, such as density and effective atomic number, can be changed by inserting heavy metal oxides into the glass network for use as radiation shielding material [9][10][11].…”

Gamma radiation shielding studies on highly dense barium bismuth borate glasses

“…), which have shown enhanced radiation shielding characteristics. 6,9,11,12,14,19,21,[24][25][26][27][28][29][30] As glasses with HMO constituents, especially those of high bismuth content, are found to be effective in radiation shielding, we have investigated the gamma attenuation characteristics of bismuth borate glasses modified with different fractions of BaO in this study. Barium and bismuth content were varied in equal mole fractions of BaO and Bi 2 O 3 , that is, x(BaO-Bi 2 O 3 )-(1-x)B 2 O 3 (herein after referred to as barium bismuth borate [BBB]) system, where x = .15, .25, .…”

“…Specifically, there are reports on high‐content bismuth‐based glasses and glasses modified with different amounts of HMO (e.g., BaO, Bi 2 O 3 , etc. ), which have shown enhanced radiation shielding characteristics 6,9,11,12,14,19,21,24–30 …”
