Gamma, X-ray and neutron interaction parameters of Mg-Gd-Y-Zn-Zr alloys

The X-ray and gamma interaction parameters such as mass attenuation coefficient, linear attenuation coefficient, Half Value Layer (HVL), Tenth Value Layer (TVL), effective atomic numbers, electron density, exposure buildup factors, relative dose, dose rate and specific gamma ray constant are studied in the Mg-Gd-Y-Zn-Zr alloys of different composition such as Mg-8.2Gd-3.8Y-1.0Zn0.4Zr, Mg-8.2Gd-4.3Y-1.0Zn0.4Zr, Mg-8.2Gd-4.8Y-1.0Zn0.4Zr, Mg-8.2Gd-5.3Y-1.0Zn0.4Zr, Mg-8.2Gd-5.8Y-1.0Zn0.4Zr, Mg-8.2Gd-6.3Y-1.0Zn0.4Zr, Mg-8.2Gd-6.8Y-1.0Zn0.4Zr, Mg-8.2Gd-7.3Y-1.0Zn0.4Zr and Mg-8.2Gd-7.8Y-1.0Zn0.4Zr. It is also studied the neutron shielding properties such as coherent neutron scattering length, incoherent neutron scattering lengths, coherent neutron scattering cross section, incoherent neutron scattering cross sections, total neutron scattering cross section and neutron absorption cross sections in the same Mg-Gd-Y-Zn-Zr alloys. A detail analysis of X-ray/gamma and neutron interaction in the Mg-based alloys reveals that the Mg-based alloy Mg-8.2Gd-7.8Y-1.0Zn0.4Zr is good absorption of both X-ray/gamma and neutron radiation. Hence we may suggest that this alloy can be used for the shieldding for X-ray/gamma and neutron radiation.
