“…The value differences between the experimental and the theoretical results suggest systematic errors; these may be due to the nonstoichiometry ratio of the glass formula after melting at high temperature. The half-value layers of the glass samples with Bi 2 O 3 content were compared with serpentite concrete, ordinary concrete, chromite concrete and barite concrete at 662 keV [6,13]; the results are shown in Figure 2(b). It was found that at 35wt% of Bi 2 O 3 , the half-value layer of the glass samples was shorter than that of all the standard shielding concretes, indicating that the glass in the present study may be developed as radiation shielding material.…”

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.

Melt and quench technique was used for the preparation of glassy samples of the composition 0.40 MO-0.60 B 2 O 3 where MO contains oxides of lithium, sodium, potassium and bismuth. 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 and effective atomic number at various photon energies is calculated. Values of half value layers have been compared with concretes. Density and molar volume studies have been carried out to get the idea regarding rigidity of glass network.

Abstract. Cantera is a quarry tuff widely used in the building industry; in this work the shielding features of cantera were determined. The shielding characteristics were calculated using XCOM and MCNP5 codes for 0.03, 0.07, 0.1, 0.3, 0.662, 1, 2, and 3 MeV photons. With XCOM the mass interaction coefficients, and the total mass attenuation coefficients, were calculated. With the MCNP5 code a transmission experiment was modelled using a point-like source located 42 cm apart from a point-like detector. Between the source and the detector, cantera pieces with different thickness, ranging from 0 to 40 cm were included. The collided and uncollided photon fluence, the Kerma in air and the Ambient dose equivalent were estimated. With the uncollided fluence the linear attenuation coefficients were determined and compared with those calculated with XCOM. The linear attenuation coefficient for 0.662 MeV photons was compared with the coefficient measured with a NaI(Tl)-based J-ray spectrometer and a 137 Cs source.
