The Gamma-Ray Interaction Study of Gallium Gadolinium Borate Glass in Energy Range from 0.015 to 15 MeV using the Phy-X Program

Abstract

The gamma-ray interaction study of gallium gadolinium borate glass in the compositions of (72.5-x)B2O3 : xGa2O3 : 27.5Gd2O3 (where x is 0, 5, 10, 15, and 20 mol%) were computed by the Phy-X program in the energy range 0.015 to 15 MeV. From the calculation result, the mass attenuation coefficients, effective atomic number and effective electron density show the same trend in this energy range. The results show the rapid decrease with gamma ray energy in energy range 0.015 to 0.2 MeV and the K absorption edge were appear at 0.06 MeV. In the energy range 0.2 to 2 MeV, the results were decrease with the incoherent scattering is the main interaction. The results show increasing with a little at energy beyond 2 MeV. The mass attenuation coefficients show the closely values when compared. The effective electron density values show the decrease with the increasing of Ga2O3 concentration in glass matrix. The effective atomic number were decrease with gallium oxide content in energy range 0.015 to 0.2 MeV and show the increase at energy higher than 0.2 MeV. These results reflected to the radiation shielding ability of the gallium gadolinium borate glass in radiation shielding applications.
