“…The highest attenuation can be seen for N-acetylcysteine due to the existence of S element in the chemical composition of this sample (see Table 1). This interesting observation supports the fundamental concepts of gamma interactions with matter [43,44]. Figure 4 describes the attenuation properties of the investigated flavonoid samples in terms of half value layer (T 1/ 2 ) as a function of energy up to 15 MeV.…”

The chemical and physical characteristics of several flavonoid compounds such as geraniol, thymoquinone, betaine, apigenin, N-acetylcysteine, catechin, l-carnosine, epigallocatachin, and saponarin were examined in this work. Numerous molecular properties of all flavonoid compounds used in this study were calculated using the Calculate Molecular Properties module of Accelrys Discovery Studio v20.1.0.19295.0. These properties included molecular polar surface area, total solvent accessible surface area, and heat of formation. We used the MCNPX general-purpose Monte Carlo code in combination with the Phy-X PSD software to determine gamma-ray interaction parameters such as attenuation coefficients, effective atomic numbers, and buildup factors. The findings indicate that the flavonoids’ elemental compositions have a direct effect on their chemical and physical properties. Additionally, a synergistic interaction of chemical and physical behaviors has been observed. Among the flavonoids studied, saporanin was shown to have the highest polar surface area and solvent accessible surface area, as well as the highest stability. Additionally, saporanin had the strongest gamma-ray attenuation characteristics across a broad photon energy range. It may be inferred that saporanin’s elemental structure enables a synergistic relationship between its chemical and physical characteristics. The findings of this study may contribute to the evaluation of saporanin’s hypoglycemic, antibacterial, and hepatoprotective effects.

“…Six components, radioactive source, primary γ-rays collimator, sample, secondary γ-rays/detector collimator, and detector, were described by a cell in the text format file. The radioactive source was positioned inside the back of a lead collimator of the primary γ-rays 50 . A γ-rays point source was identified as an SDEF mono-energetic beam for each input file 40 , 51 .…”

The current study assessed two concrete mixes prepared using dolomite and barite/limonite aggregates to shield against both energetic photons and neutrons. After that, a designed mix which comprised barite/goethite aggregates plus fine-powdered boron carbide additive, was proposed to improve the overall radiation shielding properties and in the same time, doesn’t compromise or even improve the physic-mechanical properties of the mature concrete. The assessment started first with intensive experimental investigations to investigate the prepared mixes’ shielding capabilities against both γ-rays and fast neutrons. Then, analytical computations were performed via number of reliable software programs such as; Phy-X, NXCom, MRCsC, JANIS-4, and MCNP5, in order to confirm the experimental results and to validate the created Monte-Carlo models. Finally, an intensive radiation shielding assessment for all concrete mixes understudy using, mainly, the validated MCNP models, was performed. The obtained results have revealed the superiority of barite mixes over the dolomite mix concerning attenuating photons moreover, the proposed designed mix has shown superiority over the other two prepared mixes considering shielding against; energetic photons, fast/thermal neutrons, and secondary emitted γ-rays, which nominates this mix to be a suitable universal shield that can be used even in mixed radiation fields.

Understanding the influence of rare-earth ions in tellurite-rich glass is vital for developing the technology. With this motivation, the present study analyzes the radiation shielding, physical, structural, mechanical, and acoustic features of the tellurite glasses added Nd 2 O 3 rare earth material. Five different glasses coded as TMNd0.0-TMNd1.9 are simulated via MCNPX Monte Carlo code by varying the concentration of neodymium oxide (Nd 2 O 3 ) and the related characteristics are evaluated between 0.01 and 10 MeV. The obtained results reveal that Nd 2 O 3 has a favorable influence on the radiation shielding characteristics of the preferred glass sample. To assess the relation between Nd 2 O 3 concentration in tellurite glass and corresponding structural and mechanical changes in candidate glasses, Makishima-Mackenzie theory is applied and mechanical moduli are extracted. The structure and dimensionality of the preferred samples are derived based on the Bergman and Kantor model for fluid and compositions with the help of the fractal bond connectivity. In addition, the longitudinal velocity (V L ), transverse velocity (V S ), mean velocity (V mean ), and acoustic impedance (Z i ) related to the TMNd glasses are evaluated.
