    • "Berger et al. (1987) developed XCom for calculating m r or photon interaction cross-sections for any element, compound or mixture at energies from 1 keV to 100 GeV. Windows version of XCom is being called WinXCom (Gerward et al., 2004). The attenuation (the scattering and the absorption) of photons is related to the density and atomic number of an element. "

    ABSTRACT: Soda lime glasses doped with CeO2, Nd2O3 and MnO2 were prepared. Thermoluminescence (TL) properties, such as glow curves and linearity of TL response on irradiation dose were investigated. Results showed that the TL properties depended on the type and concentration of the dopants. Samples were selected to calculate energy trap depth parameters. To design materials for radiation dosimetry, physical properties, ion concentration, elastic properties and effective atomic numbers are important. Theoretical bond compression models were used to determine the elastic moduli for comparison with experimental values. Results show fair agreement between theoretical and experimental measurements. The high elastic moduli of the glass samples indicated high rigidity and stability of the glass matrix structure.

    • "The mass attenuation coefficient (l m = l/q) is more convenient to be used as it is related to reaction cross section, r (cm 2 ) for X-and c-rays: l m = N 0 r, where N 0 is the number of atoms (or molecules) per unit volume of material [2]. Several attempts has been made for theoretical calculations of mass attenuation coefficient for different compounds using XCom or Geant4 computer codes [18] [19] [20]. "

    ABSTRACT: In the present work the effect of concrete incorporation with two types of nano-lead compounds on its gamma-ray shielding characteristics is investigated. The concrete samples were prepared according to the local standards of building materials and doped by different percentages of PbO and PbTiO3 nano powders which were prepared using co-precipitation and oxalate precursor techniques, respectively. In addition, commercial PbO2 powder additive was used to check the effect of particle size on concrete attenuation properties. The phase composition and particle size of all the lead-oxide additives were confirmed by XRD and TEM imaging. The gamma-rays attenuation coefficients were measured as a function of the additive percentage of lead compounds for gamma-ray energies of 662, 1173 and 1332 keV using 137Cs and 60Co sources. The microstructure changes occurred in the concrete samples doped with Pb compounds additives were probed using the positron annihilation spectroscopy (PAS) and the results were compared with that for normal concrete. The obtained data revealed that the overall defect density of the investigated samples, as seen by the positrons, decreases with increasing the nano-PbO contents which is in agreement with the determined values of the samples apparent densities. It was found that the gamma-ray attenuation coefficient of concrete doped by nano-PbO is improved. The results are explained in the view of the fine structure enhanced modification and its impact on the gamma-ray interaction probability at different energies.
