“…In the third layer, substances with low atomic number are used to weaken the secondary electrons by producing minimum secondary X-rays. In this structure, the material of the middle layer with a high atomic number does not cause the production of secondary X-rays since the electrons in the primary layer are weakened (Arif Sazali et al 2019;Hussein et al 2020;Vepsäläinen et al 2020;Rudychev et al 2023).…”

The safety of electronic components used in aerospace systems against cosmic rays is one of the most important requirements in their design and construction (especially satellites). In this work, by calculating the dose caused by proton beams in geostationary Earth orbit (GEO) orbit using the MCNPX Monte Carlo code and the MULLASSIS code, the effect of different structures in the protection of cosmic rays has been evaluated. A multi-layer radiation shield composed of aluminum, water and polyethylene was designed and its performance was compared with shielding made of aluminum alone. The results show that the absorbed dose by the simulated protective layers has increased by 35.3% and 44.1% for two-layer (aluminum, polyethylene) and three-layer (aluminum, water, polyethylene) protection respectively, and it is effective in the protection of electronic components. In addition to that, by replacing the multi-layer shield instead of the conventional aluminum shield, the mass reduction percentage will be 38.88 and 39.69, respectively, for the two-layer and three-layer shield compared to the aluminum shield.

“…Three factors should be considered: time, distance, and shielding. 1 Shielding materials have been developed using lead, which has been the most preferred choice due to its low cost and suitability for attenuating radiation as it has high atomic number (Z = 82). However, lead has several drawbacks, such as being heavy, fragile, toxic, and harmful to the environment.…”

Thermoplastic natural rubber (TPNR) based on polybutylene adipate terephthalate (PBAT)/natural rubber (NR) has been prepared to develop flexible radiation shielding materials by adding antimony oxide (Sb2O3). TPNR composites were prepared with a composition of NR 40% and PBAT 60%, at various loading levels of antimony oxide. The properties of the resulting composites, such as tensile strength, elongation at break, hardness, and specific gravity of TPNR composites, were investigated. Gamma‐ray shielding properties were measured under the exposure of gamma rays in the energy range of 0.223–0.662 MeV by Compton scattering technique. X‐ray shielding properties were measured with a high‐frequency digital radiography X‐ray machine at 70–120 kVp and 40 mAs. The results show that the gamma‐ray shielding properties, such as the values of mass attenuation coefficient (μm), effective atomic number (Zeff), and effective electron density (Neff) of materials, increased with increasing amounts of Sb2O3. Similar results were observed for X‐ray shielding properties. The half‐value layer (HVL) values of all samples decreased with increasing Sb2O3 content. The obtained results confirm that TPNR/Sb2O3 can be effectively used as an alternative flexible radiation shielding material.
