“…Also, using the same experimental setup, few polymers have been studied with the determination of mass attenuation coefficient, total cross section, molar extinction coefficient, effective atomic number, and electron density ( μ m , σ t , σ e , ε , Z eff , and N eff ) for gamma-ray shielding application using NaI (Tl) scintillation detector and XCOM program. Among the chosen samples, nylon 1,1 showed better shielding capabilities (More et al 2017 ). Polymethyl methacrylate and kapton polyimide polymers were investigated and their gamma-ray attenuation parameters such as mass attenuation coefficient, total and electronic cross section, molar extinction coefficient, effective atomic number, and electron density were measured using NaI (Tl) crystal detector in the energy range 84–1330 keV.…”

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.

“…Then the atoms move and can be work as projectile to excite other atoms and produce secondary displacements. Gamma rays are most conventional irradiation process that can directly produce electronic excitation (More, Bhosale, & Pawar, ). Gamma rays are short wavelength waves and its interaction with one atom usually consumes a large fraction of the energy.…”

Digital holographic interferometry (DHI), X‐ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR) and scanning electron microscopy (SEM) were used to study the effects of gamma irradiation on the physical and structural properties of basalt fibers. For this purpose, set samples of basalt fibers were subjected to different doses of gamma irradiation (3, 10, 25, and 40 kGy). The Mach–Zehnder interferometer was used to capture holographic patterns which are used then to determine the unwrapped phase. From the unwrapped phase distributions, the optical path difference within the irradiated basalt samples was determined. Thus, refractive indices, and birefringence of irradiated basalt fibers were determined at different irradiation doses using DHI method. XRD technique was used to investigate the effect of irradiation doses on the crystalline behavior of fibers. FTIR was performed to each of the basalt samples to evaluate the changes in the surface chemical properties due to radiation exposure doses. The morphology of irradiated fibers was examined using SEM. The results indicate that basalt fiber has a resistance to gamma radiation. There are no significant effects on the physical, structural and chemical properties were demonstrated of basalt fibers in the doses range of irradiation.

“…Gamma-ray shielding properties of bentonite clay /PVA Polymer Matrix were theoretically examined and the obtained results were compared with experimental data in the energy range 662 to 1332 keV by Sallam et al 19 Photon and neutron absorption parameters of some polymers which were lead monoclinic-(I), lead monoclinic-(II), lead tetragonal, azelato barium (II) polymer, 1-D coordination barium polymer (I), helical lead (II) coordination polymer, calcium bromide polymer (I), calcium bromide polymer (II), 1D-cadmium coordination polymer, and 2D-cadmium coordination polymer were calculated by Nagaraja et al 20 and their results showed that X-ray and gamma radiation absorption properties of helical lead (II) is higher than other investigated polymers while neutron absorption properties of 1D coordination barium polymer (I) is higher than other investigated polymers. 40 Radiation shielding properties of lead, gadolinium, bismuth doped polymers which are poly-acrylonitrile, polyethylene, and kevlar were investigated by Khan et al 21 and they reported that lead-based polymeric nano-fiber compound is suitable for industrial and medical areas. 41 42 and their results indicated that gamma-ray absorption properties of nylon 1,1 were better than other investigated samples.…”

As radiation is an essential tool in various technological applications, searching for a suitable shield is an urgent demand to minimize its damaging effects on human beings. In this research article, we report on the radiation shielding properties of some commercially available polymers namely poly(N-isopropylacrylamide), polyethylene terephthalate, polystyrene, and polycarbonate (denoted by P1, P2, P3, and P4, respectively). The gamma ray attenuation parameters are calculated using the Geant4 simulation, PHITS code, and XCOM program. Half value layer (HVL), linear attenuation coefficient (LAC), gamma dose rate at different energy levels, mean free path (MFP), specific gamma ray constant, effective atomic number (Z eff ) and effective electron density (N eff ), removal cross section for fast neutron, and total cross section for thermal neutron are investigated at energies of 0.01, 0.03, 0.05, 0.07, and 0.1 MeV.The results indicate that the highest LAC values were observed for P2 polymer at 0.1 MeV, while the lowest LAC values were noted for P3 polymer at 0.01 MeV among the studied commercial polymers. The total cross sections of thermal neutrons for the investigated polymers change from 24.0717 to 31.8611 cm −1 . Moreover, the MFPs and HVLs of the investigated polymers were very close to those of ordinary concrete and RS-253-G18 commercial glass, especially at the low energies. This suggests the utility of using the present polymer samples for shielding applications against gamma and/or neutron radiations.
