“…Therefore, degraded energy photons exist for a longer time, which results in their buildup in the material. Photoelectric absorption has low importance, since these glass materials have high values of effective atomic number, Z eff [7,16]. It is well established that the photoelectric cross-section is proportional to Z 4−5 and inversely proportional to E 7/2 .…”

Gamma ray exposure buildup factors for three Heavy Metal Oxide (HMO) glass systems, viz. PbO-Bi2O3-B2O3, PbO-B2O3, and Bi2O3-B2O3 glasses are presented. The computations were done by interpolation method using the Geometric Progression fitting formula and ANSI/ANS-6.4.3 library for the energy range from 0.015 to 15 MeV, up to penetration depths of 40 mfp (mean free path). The buildup factors have been studied as functions of incident photon energy and penetration depth. The variations in the buildup factor, for all the glass systems, in different energy regions, have been presented in the form of graphs. Buildup factors of these HMO glasses cannot be found in any standard database, but they are useful for practical calculations in gamma ray shield designs, and they also help to determine and control the thickness of the shielding material used.

“…They observed that at high energy regions, the lead free glasses showed higher values of effective atomic numbers than lead based glasses. Manohara et al [7] studied the effective atomic numbers and related parameters for CaOSrO -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 energy ranges from 1 keV to 1 GeV. They found that for medium-Z glasses, effective atomic number was nearly constant and equal to the mean atomic number in a wide energy range dominated by Compton scattering process.…”

Abstract:The glasses studied here have been prepared by the melt quenching technique from Egyptian rice husk silica.The obtained solid glasses exhibit amorphous nature and transparency. These glasses were selected to obey the following composition, (75-x) mol % RH silica. 25mol % Na 2 O. x mol % Bi 2 O 3 , where x takes the values, 0, 5, 10, 15 and 20. It was found that, as Bi 2 O 3 was gradually increased both the density and molar volume values increased. The comparison between the experimental and empirical density and molar volume values confirm that all the studied glasses are in amorphous glassy phase. Moreover, all samples showed also good shielding properties against gamma ray radiation and neutrons. The mass attenuation coefficient of gamma ray radiation increased gradually as Bi 2 O 3 was gradually increased while the HVL values exhibit gradual decrease, and the sample that contains 20 mol % Bi 2 O 3 appeared the efficient one at low gamma ray energy (especially at 356 KeV). On the other hand "for shielding neutrons" the sample that contains 5 mol% Bi 2 O 3 appeared the best one since it exhibits the highest neutron removal cross section.
