Abstract
The aim of this investigation was to present the gamma-ray and neutron shielding properties of different type of Ga additive Pd/Mn binary alloys. Therefore, mass attenuation coefficient (μm) values of different types of Pd-Mn-Ga alloys were calculated using the MCNPX simulation code in the 0.02–15 MeV energy region. Afterwards, the obtained μm values have been utilized for determination of HVL, TVL, MFP and Zeff gamma shielding parameters for evaluation of the gamma radiation shielding abilities of alloy samples. Moreover, effective removal cross-sections (∑R) of investigated alloy samples have been calculared. The results showed that both μm and Zeff values are increased as the Ga concentration increases. Thus, the study is indicates that 25Ga alloy sample owns distinguished protection ability to attenuate the gamma-ray radiation. The results also showed that 0Ga alloy sample which containing %0 of Ga has the highest ∑R value as a most effective alloy sample among the other samples for fast neutron shielding. To observe the shielding paerformance of superior sample, we have compared our results with previous available investigations in literature. It can be concluded that Ga additive for this type of binary alloys can help to increase the shielding gamma-ray performance.
