“…The experimental and theoretical mass attenuation coefficients were found to be in a good agreement. The discrepancies are considered not to be very large because the differences are in the range of the reported experimental errors, which is < 3.5% [13]. A comparison of the measured mass attenuation coefficient values for different kinds of samples at the same energy measured in different countries is shown in Table 5.…”

The main goal of this work is to find natural rock materials that can be used as effective gamma rays shielding at minimal cost, reliability and wide applications. It must be at particular weight and volume (lighter and more protection). Natural bentonite clay can be used as shelters from nuclear waste because of its large availability and low cost. Bentonite clay was used in two forms naturally as it is from its ores and in ground phase. Natural bentonite was cut into cylindrical pellets at different thicknesses; also, the other form pressed into cylindrical pellets with different thicknesses and different pressing pressures (50, 100 and 150 bar). The different samples are coated with polyvinyl alcohol polymer to prevent nuclear waste leakage through porosity of clay. Chemical analysis and density are measured for all samples. Bentonite clay was found naturally in nanometer scale because it is formed from volcanic ash deposits. The nanoparticle size was determined by dynamic light scattering and Williamson-Hall size analysis using XRD patterns and the help of X-powder program. The particle size of natural bentonite was found to be 59.79 nm. The microstructure was characterized by scanning electron microscope and transmission electron microscopy. The linear and mass attenuation coefficients of nano-structured bentonite clay (natural and pressed) were determined at 662 keV energy of 137 Cs; at 1173 and 1332 keV energies of 60 Co, gamma ray sources were determined by using NaI(Tl) scintillation detector. The experimental results showed that the ground bentonite pressed at 150 bar gave the highest linear and mass attenuation coefficients than other samples. The theoretical and the experimental calculations of mass attenuation coefficient were found to be in a good agreement.

“…In the recent years, there has been increasing interest in using glass materials as radiation shielding. Several researchers, have attempted to prepare lead free glasses [2][3][4][5][6]. It is observed that, for bismuth borosilicate glasses the mean free paths have lower values than the values of several types of standard shielding concretes [7,8].…”

“…Glasses appeared now of special interest because they are optically transparent and easy manufactured. Therefore gamma-ray attenuation parameters have been thoroughly investigated for various types of glasses specially those containing heavy metal ions (HMIs) [ (Abdel_Ghany et al 2015), (Bagheri et al, 2016), (Kaewjaeng et al,2012), (Chahine et al, 2004), (Kirdsiri et al, 2011)]. Among various glass types, boro-silicate glasses represent an interesting glass family in the field of glass science.…”

The attenuation of gamma-ray radiation depends mainly on the energy of the incident gamma photon, the effective atomic number, density of the elements in the shielding material and the thickness of such shield. However, in this work, mass and linear attenuation coefficients, effective atomic number and electron density, mean free paths, half value layer and 10 th value layer of some barium-bismuth-boro-silicate glasses were obtained at gamma-ray photon energies of 0.662, 1.173 and 1.332 MeV, by using Win-XCOM computer program. The obtained data were then compared with the experimental data. The obtained theoretical results were found in good agreement with these obtained experimentally. According to the obtained results, it can be stated that, Boro-silicate glasses containing mixed heavy metal oxides (BaO and Bi2O3) appeared to be transparent and have good gamma-ray shielding properties. But the best glass sample that can act as good attenuator is that containing 25 mol% Bi2O3, at low gamma-ray energy photons.
