Abstrakt: The X-ray and gamma radiation shielding parameters (mass attenuation coefficient, mean free path, half value layer, tenth value layer, effective atomic numbers, electron density, exposure buildup factors, relative dose, dose rate and specific gamma ray constant) have been studied for the Al-based glassy alloys Al 86 Y 7 Ni 5 Co 1 Fe 0.5 Pd 0.5 , Al 85 Y 8 Ni 5 Co 1 Fe 0.5 Pd 0.5 , Al 84 Y 9 Ni 4 Co 1.5 Fe 0.5 Pd 1 , Al 80 Y 13 Ni 5 Co 1 Fe 0.5 Pd 0.5 , Al 70 Y 23 Ni 5 Co 1 Fe 0.5 Pd 0.5 and Al 60 Y 33 Ni 5 Co 1 Fe 0.5 Pd 0.5. For the same alloys, the neutron shielding parameters (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) have also been explored. Al 60 Y 33 Ni 5 Co 1 Fe 0.5 Pd 0.5 was found to be a good shielding material for the X-ray/gamma radiation, while Al 86 Y 7 Ni 5 Co 1 Fe 0.5 Pd 0.5 is a good shielding material for neutrons.
