The mass attenuation coefficients and partial interactions of BaO-ZnO-B2O3 glasses have been investigated using WinXCom program at difference photon energy. BaO-ZnO-B2O3 glasses were prepared in composition xBaO: 20ZnO: (80-x)B2O3 (where x = 15 and 20 mol %) by melt quenching technique under normal atmosphere. The densities of glasses are 3.0052 and 3.1022 g/cm3, respectively. The mass attenuation coefficients at 20% mol are higher than 15% mol of BaO in all energy range. The optical spectra were measured and good transparent behavior was obtained. Half value layer (HVL) of glasses are also report and compared with same standard shielding materials and show better shielding than ordinary concrete.

Understanding the characterization of photon interaction is vital in nuclear science and technology field. The information obtained from mass attenuation coefficients (μ / ρ) and effective atomic numbers Zeff are compared with the reference value for good interpretation of radiation interaction with matter. However, the methods of Zeff calculation sometimes are confusing. In the present work, the total mass attenuation coefficients (μ / ρ) T for photon interaction of Dy2O3 doped strontium borate glasses have been calculated using database tabulated by Hubbell and Seltzer, at the energies of 0.6 MeV and 1.25 MeV. For the calculation of the Zeff, the power law, cross section and Auto-Zeff are selected for comparison purpose in the energy range of 0.01 – 1.25 MeV. The relationship between the (μ / ρ) T andZeff clearly shows the increase in the value with the increase of Dy2O3 concentration. These variations are due to the major dominance of photoelectric effect and minor interaction of incoherent scattering. It is found that the calculation of Zeff between cross section and power law method is comparable at photon energy less than 0.1 MeV. As photon energy exceeds 0.1 MeV, the cross section method and the Auto- Zeff software are more preferred compared to the power law approach. It is recommended to use different approach of Zeff calculation at the specific energy of interest.

In this work, total mass attenuation coefficients and effective atomic numbers of a series of three host glasses with different chemical composition, 65RmOn: 10CaO : 25Na2O mol% (where RmOnare B2O3, SiO2and P2O5, respectively) have been studied as a function of photon energy. The total mass attenuation coefficient values were taken from WinXCom program, were used to evaluate the effective atomic numbers in the energy range from 1 keV to 100 GeV. The obtained results for all samples are compared and discussed.
