“…This finding contrasts with ECS, where the order was solely dictated by the incidence energy of photons. The comparison with previous work by Dhobi et al (2021) on the Klein Nishina differential equation for radiation shielding materials emphasizes the nuanced nature of these interactions. Furthermore, the TMCS values are observed to be greater than ECS.…”

“…The scattering of the incident photon is characterized by an angle θ, which is determined by the Klein-Nishina differential cross-section equation. This equation, as outlined by Dhobi et al in 2021, provides a mathematical description of how the incident photon scatters at different angles, offering insights into the Compton scattering phenomenon at this specific photon energy (Dhobi et al, 2021):…”

Radiation shielding is a critical practice involving the utilization of materials or barriers to safeguard against ionizing radiation by absorbing, scattering, or blocking the radiation. Its primary objective is to curtail exposure and mitigate potential health risks associated with radiation. In diverse fields like medicine, industry, and nuclear applications, radiation shielding materials play a pivotal role in ensuring the safety of individuals and equipment, contributing significantly to the maintenance of secure environments. This study focuses on characterizing materials for radiation shielding, particularly of Platinum group alloys in varying compositions with hydrogen. Using the Klein-Nishina (KN) formula, the investigation calculates electronic cross-sections (ECS), total mixture cross-section (TMCS), and mass attenuation coefficient (MAC) for different weight percentages of Platinum group alloys (0.1 to 0.6) when exposed to γ-ray photons of various energies. The outcomes emphasize the strong dependence of these cross-sections and MAC on photon energy and the charge number of the material, revealing a decrease with increasing photon energy and an increase with the charge number to mass number ratio (Z/A). The research underscores that fundamental parameters such as charge number, photon energy, and Z/A can be manipulated to enhance the utility of these elements in radiation shielding, protection, dose measurements, and imaging. The study's implications extend to the optimization of Platinum Group alloy compositions, offering insights for the development of tailored materials with enhanced shielding effectiveness in radiation protection and safety applications.

The objective of this work is to study the Klein-Nishina (KN) cross section during the collision of free electrons and atoms (H-atom and Pt-atom) near the cathode of Proton Exchange Membrane Fuel Cell (PEMFCs). The developed KN cross section was computed using MATLAB shows KN cross section decrease with an increase with the temperature. The maximum KN cross section recorded for single scattering is about -70.2m2 and -66m2 in natural log terms during the collision of free electrons with H-atom and Pt-atom, respectively. The maximum KN cross section recorded for 1ml flow of hydrogen is about -26.6m2 and -22.25m2 in natural log term during the collision of free electrons with H-atom and Pt-atom, respectively.

In this study, we investigate the Klein-Nishina differential cross-section equation for total cross-section and extend it to calculate the total molecular cross-section for compounds Al2O3, PbO, and Fe2O3. Our findings reveal that the total molecular cross-section of these compounds is significantly larger, with values 5 times greater than the total atomic cross-section. Furthermore, we determine that the molecular cross-section of Al2O3, PbO, and Fe2O3 is 73, 132, and 118 times greater than the total electronic cross-section, respectively, while the atomic cross-section of these compounds is 15, 66, and 24 times greater. At low energy levels ranging from 1-5 MeV, the entire molecular, atomic, and electronic cross-section dominates due to Compton scattering. However, as the photon energy increases, Compton scattering becomes negligible, and a slight contribution from pair production scattering is observed. We also establish the adequate atomic numbers for Al2O3, PbO, and Fe2O3, which are determined to be 15, 66, and 24, respectively. These results highlight the significance of mass attenuation, cross-section, and adequate atomic number in the selection of radiation shielding materials for various protection purposes. The findings from this study provide valuable insights into the properties and behavior of these compounds, enabling informed decisions in radiation shielding applications.
