Due to their excellent heat resistance, superalloys are used predominantly in the manufacturing of engine parts and accessories for aircraft and aerospace equipment. The Monte Carlo simulation (MCNP-5) code was performed to estimate the mean track length of the incident photons inside six different alloys. Then, based on the simulated track length, other important γ-ray shielding parameters were calculated. In this study, the highest mass attenuation coefficient was obtained for alloys encoded MAR-302 and MAR-247 and varied in the range 0.035–72.94 and 0.035–71.98 cm2·g−1, respectively. The lowest mass attenuation coefficient was found for alloys coded Inconel-718 and Nimocast-75 with a range of 0.033–59.25 and 0.32–59.30 cm2·g−1, respectively. Use was made of a recently developed online program Phy-X/PD to calculate the effective atomic number, equivalent atomic number, and the buildup factors for the alloys of interest. The effective removal cross-section for the fast neutron was also calculated for the studied alloys: the highest value was found for the alloys coded with Inconel-718 (∑R = 0.01945 cm2·g−1) and Nimocast-75 (∑R = 0.01940 cm2·g−1), and the lowest value was obtained for alloy coded MAR-302 (∑R = 0.01841 cm2·g−1). Calculated data indicate that MAR-302 and MAR-247 are superior candidates for shielding of gamma-rays, while Inconel-718 and Nimocast-75 MAR-302 are suitable for the shielding of fast neutrons.

In this work, shielding parameters of LAS (lithium-aluminum-silicate) Li2O-Al2O3-SiO2 glass samples have been reported with the help of the WinXCom code, a Windows version of the XCOM database. The effect of increasing P2O5 concentration on the shielding parameters has been examined in the used Li2O-Al2O3-SiO2 glass samples. The shielding effectuality of the materials for gamma-ray can be interpreted with the help of several different attenuation parameters which plays key role in understanding the shielding capabilities of the material. The mass attenuation coefficient, defined by = / , is the most basic coefficient used to calculate the shielding parameters. These parameters are the mean free path (MFP), half value layer (HVL), tenth value layer (TVL), effective electron number (Ne) and equivalent atomic number (Zeq). The exposure buildup factor (EBF) and GP fitting parameters are also calculated by the method of logarithmic interpolation using Zeq of a Li2O-Al2O3-SiO2 glass system. The EBF values for Li2O-Al2O3-SiO2 glass samples show an inverse relation with Ne. Further, P1 (least Ne) offers maximum values of EBF and P6 (highest Ne) offers minimum EBF values. The change in different shielding parameters for the selected glasses was interpreted by considering three interactions with the substance (Photoelectric effect, Compton scattering and pair production). The obtained results show that the strongly depends on the photon energy, chemical composition and density of the shielding materials. It is clear to see that P6 glass sample having the highest P2O5 concentration is the most effective glass sample among the other glasses of Li2O-Al2O3-SiO2 system in nuclear radiation shielding ability.

In this study, three different sliding bearing alloy samples were investigated in terms of their performance on attenuation characteristics and behavioral attitudes under 0.015–15 MeV gamma-ray exposure. Accordingly, different types of advanced calculation methods were utilized to calculate the radiation shielding parameters. Next, several gamma-ray shielding parameters and exposure rates in addition to fast neutron removal cross-section were determined. Furthermore, exposure and energy absorption buildup factors were determined by using G-P fitting method. Mass attenuation coefficients (MAC) values were recorded as 2.5246, 2.5703, and 2.5827 (cm2/g) for Alloy1, Alloy2, and Alloy3 samples at 15 MeV photon energy, respectively. At 40 mfp, the highest EBF values were reported as 1,376,274, 1,003,593, and 969,373 for Alloy1, Alloy2, and Alloy3 samples. The results of this extended investigation showed that the Alloy3 sample with the highest Pb reinforcement amount has superior shielding capability among the investigated samples. It can be concluded from the results that substitution of Pb with Bi in the recent alloy structure has a monotonic effect on different types of shielding parameters. Therefore, it can also be concluded that Pb is a remarkable tool for the improvement of the shielding properties of studied alloy structures.
