“…• The atomic number of the constituent elements in the alloy has a major impact on the values of Zeff and Neff. • Interpolation and direct methods have produced similar results and agree with the experimental results in the literature (Gunoglu et al, 2021;Abdel-latif & Kassab, 2022). • HVL, MFP, and TVL values are highest in the neighborhood of 10 MeV energy for all steels.…”

In this work, we investigated the effective atom number, the effective electron density, the mean free path, the tenth-value layer, the half-value layer, and the mass attenuation coefficient for some stainless steels: AISI 302, AISI 303, AISI 304, AISI 304L, AISI 310, AISI 316, AISI 321, and AISI 410. The mass attenuation coefficients were determined using the WinXCom computer program in the energy region 1keV- 100 GeV. The effective atom number and effective electron density have been calculated using two different methods, the direct method, and the interpolation method. The results reveal that the values of effective atomic numbers and effective electron numbers are greatly influenced by the atomic number of elements in the alloy and the interaction photon energy. The effective atom numbers grew as the atomic number of the constituents in the alloys increased. The effective atomic number and effective electron density values for all steels were found to have the highest values at 0–0.1 MeV energy and the lowest values in the 0.5–6 MeV energy range. The shielding properties of the steels produced close results, but AISI 304L provided the best protection while AISI 410 provided the least. The results obtained with both methods were also compared. The result of the present study may provide new and helpful knowledge about stainless steel for gamma-ray shielding applications.

“…Many calculations were performed using the PhyX input file, including those for the mass attenuation coefficients ( µ m ), etc. MeV’s elemental composition, densities, and energy ranges were added as PhyX input parameters 40 . The relative differences (Div., %) were also calculated by comparing the PhyX results for the CHBFX mortar samples with the MC results 41 , 42 : …”

The current work discusses the radiation attenuation capability and different shielding characteristics of different mortar samples. The samples were prepared by replacing different percentages of fine aggregate with iron filling and replacing different percentages of hydrated lime with Bi2O3 (0–50 wt.%). The prepared mortar samples are coded as CHBFX where X = 0, 10, 30, and 50 wt.%. The mass and linear attenuation coefficient was determined experimentally using a narrow beam technique, where a high purity germanium detector, and different point gamma-ray sources (such as Am-241, Cs-137, and Co-60). The linear attenuation coefficient was also calculated using the Monte-Carlo simulation code and the online Phy-X/PSD software. The comparison of the three methods showed a good agreement in the results. The linear attenuation coefficient drops from 19.821 to 0.053 cm−1 for CHBF0, from 27.496 to 0.057 cm−1 for CHBF10, from 42.351 to 0.064 cm−1 for CHBF30, and from 55.068 to 0.071 cm−1 for CHBF50 at photon energy range from 0.015 to 15 MeV. The half-value layer thickness, tenth-value layer thickness, and mean free path of the prepared mortar composites were also calculated photon energy ranged from 0.015 to 15 MeV. The fast neutron removal cross-section of the prepared CHBFX mortar samples have values of 0.096 cm−1, 0.098 cm−1, 0.103 cm−1, and 0.107 cm−1 for the mortar samples CHBF0, CHBF10, CHBF30, and CHBF50, respectively. The results showed that the mortar sample with the highest iron filing concentration, CHBF50, provides the best protection against gamma rays and fast neutrons which could be used in the nuclear and medical fields.

HAP (Hydroxyapatite) bio-composite has been used extensively to repair and replace bone and teeth tissues in the human body. However, because of the poor mechanical features of HAP bio-composites, significant enhancements in the strength and toughness of pure HAP have been achieved by the insertion of various alloys and materials into HAP. Accordingly, the present study evaluates the radiation shielding and mechanical features of the Fe2O3 -reinforced HAP composite as an implant for 0.0, 2.5, 5.0, and 7.5 wt.% Fe2O3. Also, the composite response in a magnetic field has been investigated. Employing FLUKA Monte Carlo Code, radiation shielding factors are obtained. In addition, the mechanical characteristics of the studied composites are evaluated using the theoretical method. Findings reveal that increasing the Fe2O3 contents in HAP bio-composite enhances the preferred samples’ radiation shielding and mechanical qualities. Furthermore, in the absence of a magnetic field, the particles' spatial map exhibits symmetric behavior along the x-axis, however, a different trend is observed in the presence of a magnetic field with a value of Bx=5 microT.
