“…In conclusion, the photons having high energy will have more penetration within the epoxy based composites comparing to the photon having low energy. When the results are compared with a commercial polymer composite consisting of 15 wt.% polypropylene copolymer, 75 % iron oxide powder and 10 wt.% impact modifier (QUEO 8210), since the commercial polymer composite has the mean free path values of 2.549 cm (81 keV) and 4.694 cm (356 keV) and the HVL values of 1.767 (81 keV) and 3.254 (356 kev) (Büyükyıldız et al, 2018); it was revealed that both epoxy composites include 40 wt.% PbO or 40 wt.% BaO reinforcing material exhibit better gamma radiation shielding than the commercial composite for each photon. Additionally, as expected the Epoxy /PbO composites have lower HVL, TVL and  parameters than that of Epoxy/PbO composites for both incident photon energies.…”

This study was devoted to investigate the gamma ray shielding abilities of the epoxy composites prepared by using two different reinforcing materials: barium oxide and lead oxide. The Epoxy/PbO and Epoxy/BaO composites were produced by using 10 wt.%, 20 wt.%, and 40 wt.% reinforcing materials to obtain low weight radiation shielders. The heaviness of the samples were compared with some conventional shielding materials such as lead, steel, concrete etc. The gamma ray shielding performance of the pure epoxy and the composites were measured experimentally by using NaI(Tl) detector. In the experiments, Ba-133 point radioactive source was also utilized as a gamma ray source with the 81 keV and 356 keV energies. As the gamma ray shielding parameters of the composites, the mass attenuation coefficient, half layer value and tenth layer value thicknesses and mean free path distance were considered. After comparison of the related parameters of the PbO and BaO added epoxy composites, it was revealed that the gamma radiation shielding performance of the PbO added epoxy composite can also be obtained by adding BaO to the epoxy. However, to achieve the same performance, BaO should be added twice as much as the PbO additive percentage. On the other hand, it was determined that 40 wt.% BaO added epoxy composite exhibits a better radiation shielding performance than steel, concrete and Gd2O3 nanoparticle added epoxy composite for the photons with 81 keV and 356 keV energies. Thus, a lightweight and non-toxic gamma-ray shielding material can be produced by using an Epoxy/BaO composite.

“…Büyükyıldız et al evaluated the suitability of different PPA composites, both unfilled, with glass and carbon fibers, as materials for shielding against both or either X-ray gamma radiation. 101 Using a model and wavelength dispersive X-ray fluorescence (WDXRF), they allocated the mass attenuation coefficients at 81 and 356 keV, calculating the half-value layer, mean free path, effective electron density and effective atomic number needed to measure the effective atomic number (Z eff ). The calculated models had less than a 7% difference with the recorded values.…”

The focus of this review is on the family of polymers commonly known as polyphthalamide (PPA), employed in the automotive industry along with other industries. This includes electrical parts, manufacturing or oil extraction because of PPAs chemical resistance, high strength, stiffness at high temperature, and dimensional stability. A significant amount of research was found and was divided into two main sections: first, PPA and its blends, and second, PPA composites. A consistent notation was devised to aid the understanding of older sources and enhance the comparison between different materials, increasing comprehension. Undiscovered or unpublished properties of PPAs means that there is a rich vein of opportunity, and many studies yet to be performed. This will open up a plethora of breakthrough research in electrical vehicle and aerospace applications.

“…Therefore, the shielding design for neutrons is one of the important considerations in radiation safety [6,7]. In recent years, the shielding properties of many new materials or different materials with modified characteristics have been investigated [8,9]. For effective neutron radiation shielding, the material structure should consist of hydrogen-rich or low atomic number element combinations [10].…”

In this study, the linear attenuation coefficients (LAC), mass attenuation coefficients (MAC), half-value layer (HVL), and mean free path (MFP) of various materials such as water equivalent, ABS, Presage, RMI457, RW3, SW557, Epoxy, A150, Rhizophora spp., and Nylon-12 have been calculated using the Monte Carlo simulation method, EpiXS, Phy-X/PSD, and XCOM. Additionally, the fast neutron effective removal cross sections (ΣR) have been calculated using the empirical calculation method, Phy-X/PSD, MRCsC program, experimental and MNCP5 with the help of fast neutron mass removal cross sections. Among all the materials studied, Nylon-12 has the highest ΣR value. The calculated values of HVL, MFP, LAC, and MAC reveal that RW3, Epoxy, and Presage are the best materials in terms of their shielding properties, respectively.
