“…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.

“…This change may have resulted from the boron anomaly and alkali (Na 2 O) content, known widely as a typical property of alkali borosilicate glass [14]. The mass attenuation coefficient and related shielding properties were calculated from experimental data [15][16][17][18]. The experimental values of the mass attenuation coefficients of the glass samples were evaluated using intensities of incident (I 0 ) and transmitted (I) gamma ray, while the theoretical values were calculated with the WinXCom program.…”

Abstract. In this work, Pb-free shielding glass samples were prepared by the melt quenching technique using subbituminous fly ash (SFA) composed of xBi 2 O 3 : (60-x)B 2 O 3 : 10Na 2 O : 30SFA (where x = 10, 15, 20, 25, 30 and 35 by wt%). The samples were investigated for their physical and radiation shielding properties. The density and hardness were measured. The results showed that the density increased with the increase of Bi 2 O 3 content. The highest value of hardness was observed for glass sample with 30 wt% of Bi 2 O 3 concentration. The samples were investigated under 662 keV gamma ray and the results were compared with theoretical calculations. The values of the mass attenuation coefficient (µ m ), the atomic cross section (σ e ) and the effective atomic number (Z eff ) were found to increase with an increase of the Bi 2 O 3 concentration and were in good agreement with the theoretical calculations. The best results for the half-value layer (HVL) were observed in the sample with 35 wt% of Bi 2 O 3 concentration, better than the values of barite concrete. These results demonstrate the viability of using coal fly ash waste for radiation shielding glass without PbO in the glass matrices.

The mass attenuation coefficients and partial interaction of xR m O n :(100-x)SiO 2 glass system (where R m O n are Bi 2 O 3 , PbO and BaO, with 30 x 70 % by weight) have been investigated at 662 keV on the basis of experiments and calculation. The theoretical values of total and partial interaction were obtained by the WinXCom software. The glass system was prepared by the melt-quenching method following the theoretically investigated compositions and its radiation shielding properties were measured. The experimental results showed good agreement with the theoretical ones. Total mass attenuation coefficients of glasses increased with the increases of Bi 2 O 3 and PbO component, because of the increase of photoelectric absorption. On the contrary, there was no significant change in mass attenuation coefficient when the fraction of BaO increased. These results indicated that photons were more attenuated in Bi 2 O 3 and PbO glasses than the BaO glass. The half value layer (HVL) and effective atomic number results indicate that Bi can replace Pb at this energy as a gamma-ray shielding material. For BaO, HVL was better than the ordinary concrete and commercial windows. This indicates that BaO glasses can be used to shield gamma-ray in replace of both of them in this energy. The Bi 2 O 3 and BaO glass will open new possibility for lead-free radiation protecting glasses with non-toxicity to our environment.
