A study of X-ray, gamma and neutron shielding parameters in Si- alloys

We have studied the X-ray and gamma radiation shielding parameters such as mass attenuation coefficient, linear attenuation coefficient, half value layer, tenth value layer, effective atomic numbers, exposure buildup factors and specific gamma ray constant in aluminum silicon alloys (Al-47, Al– 32S,...

Description
Summary:We have studied the X-ray and gamma radiation shielding parameters such as mass attenuation coefficient, linear attenuation coefficient, half value layer, tenth value layer, effective atomic numbers, exposure buildup factors and specific gamma ray constant in aluminum silicon alloys (Al-47, Al– 32S, Al-43, Fe–Si, Al-356, Al-355 and Al-A355). We have 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 aluminium silicon alloys. It has been compared the shielding properties among the studied aluminium silicon alloys. From the detail study it is found that mean free path, HVL and TVL is minimum and exposure buildup factor is maximum for ferro-silicon alloy. Hence it is clear that ferro-silicon alloy is good absorber for X-ray and gamma radiation. The attenuation parameters for neutron are large for ferro silicon alloy. Hence, we suggest ferro silicon alloy is the best shielding materials for X-ray, gamma and neutrons. •We have studied the X-ray and gamma radiation shielding parameters in silicon alloys.•We have also studied the neutron shielding properties.•It has been compared the shielding properties among the studied aluminium silicon alloys.•The attenuation parameters for neutron are large for ferro silicon alloy.•We suggest ferro silicon alloy is the best shielding materials for X-ray, gamma and neutrons.
