“…So it is desired to have materials which are transparent to visible light and have better shielding properties in terms of lesser volume requirement. Now a day heavy metal glasses are proving to be the promising candidates as an alternate to the conventional shielding material like concrete [4][5][6][7][8][9][10][11] . The commonly used heavy metal in glasses is lead.…”

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.

“…Decreasing band gap indicates a compaction of the glass network after irradiation. Radiation compaction includes displacements, electronic defects and breaking of the B-O bonds and thus allowing the structure to relax and fill the large interstices in the interconnected network of boron and oxygen [37][38][39]. This result is further supported by the shifting of absorption band towards higher wavelength and is attributed to the increasing number of nonbridging oxygen (NBO) atoms after breaking.…”

“…It can therefore be suggested that PbO act as network modifier in the range of 10-30 mol% of PbO in xPbO-20SrO-(80-x)B 2 O 3 glass samples. However, Limkitjaroenporn et al [23] has found that PbO plays the role of network former at lower concentration of PbO (x ≤ 20 mol%) in xPbO-20Na 2 O-(80-x)B 2 O 3 glass system. As such, the role of PbO in alkali/alkaline earth borate glass system at lower concentration is still not clear.…”
