Özet

© 2021 Elsevier LtdIn this work, five Ni-based alloys with different Cr, Fe, Cu, W, and Re metals mixtures have been prepared and coded as S0, S3, S4, S6, and S9. The crystal structure of the synthesized alloys was analyzed via X-ray Diffraction. The ability of using the prepared alloys for gamma-ray shielding applications has been evaluated via MCNP-5 Monte Carlo simulation code and Xcom theoretical program. All effective shielding factors; mass and linear attenuation coefficient, half-value thickness, and mean free path have been calculated. Mass attenuation coefficient values were ranged from 77.03 to 68.7 cm2/g for S9 and S0 alloys at 0.015 and 15 MeV, respectively. MAC values of the alloys follow the trend that (MAC)S9 > (MAC)S6 > (MAC)S4> (MAC)S3> (MAC)S0. Additionally, effective atomic number, exposure and energy absorption buildup factors have also been investigated. It is found that the sample posses high values of W + Re ratios possess highest effective atomic number. Furthermore the buildup factors have been changed according to the change in equivalent atomic number. The prepared alloys can be considered useful candidates in radiation shielding applications to reduce workers' exposure in the nuclear reactor area and medical centers.
