“…The resistance of a material to radiation is attributed to many factors such as the type of radiation used, the rate of absorbed dose, radiation exposure (pulsed or continuous), area and size of the material, the surrounding environment (pressure, temperature, electric, or magnetic field) (McMillan 2019). But in inorganic materials, the radiation resistance depends on the type of chemical bond and crystal structure of the material (Wozniak et al 2017). Due to relatively high processing ability and durability, polymer composite materials are vastly used in various fields of industry.…”

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.

“…These conditions include deep vacuum, a sharp temperature drop (from −170 to +200 °C), ionizing radiation, vacuum ultraviolet radiation, micrometeorite particles, atomic oxygen, etc. Under the influence of these conditions, many polymers are destroyed, which leads to a serious violation of their functionalities [6, 7, 8, 9, 10, 11].…”

Radiation shielding composites based on polyimide and Bi 2 O 3 were synthesized. Surface and physical-mechanical properties of polyimide/Bi 2 O 3 composites were studied. Bi 2 O 3 particles were modified by polymethylphenylsiloxane for the uniform distribution of filler in composites. This paper presents data on the production of composites in two ways: hot- and cold-pressing. The hot-pressing method for the synthesis of composites is preferable compared to the cold-pressing method (the density increases by 10–12%, and the Vickers microhardness by 10–20%). The results show that the introduction of Bi 2 O 3 significantly increases the thermal stability of the composites. At 680 °C, a polymer composite containing 10 wt% Bi 2 O 3 retains 9.7% of its mass, and at 60 wt% Bi 2 O 3 , retains 58.4%. The radiation-protective characteristics of the composites with respect to gamma radiation were evaluated by experimental and theoretical methods. High radiation-protective characteristics of the composites have been established in the gamma-quanta energy range of 0.1–1 MeV.

“…Researches are ongoing for the development of reinforced composite shields which can be customized for specific radiation shielding applications. Notwithstanding the attractive radiation shielding potentials of reinforced composite materials, this class of materials also possesses higher mechanical quality and thermal stability in contrast to a plain (unreinforced) polymer [37]. Another point of attraction in the use of reinforced composites for radiation shielding is the fact that resin and reinforcement is chosen in line with the specific area of application.…”

“…Nambiar and Yeow [38] explained that neutrons and gamma-quanta have high penetrating force, which behoves designers to structure radiation shielding materials with a thickness and density that relies upon the attributes of the materials used to attenuate them [37,38]. Polymer composites can suitably suffice for these materials as a viable safeguards against radiations.…”

This review explored recent developments in reinforced composite design and applications for improved radiation shielding and high percentage attenuation. Radiation energy moves as a wave. Thus unguarded exposure to high-energy radiation is inimical to the human tissue and the overall health standing of individuals which may result in cancer, tumour, skin burns and cardiovascular diseases. Radiation energy is conventionally contained using lead-based shields. However, recent literature has faulted the continued use of lead citing drawbacks such as high toxicity, poisoning, lack of chemical stability, heaviness and hazardous after life handling. Consequently, the trending research evidence has shown mass deviation towards the use of reinforced polymer composite as an alternative to lead due to their light weight, low cost, high resilience, good mechanical tenacity and interesting electrical properties. The present review therefore summarizes the criteria for ionizing radiation shielding material design, mechanism of radiation energy shielding, beam penetration in composite shielding materials, theoretical shielding parameters in the design of radiation protective materials, scheme of reinforced composite material selection for shielding purposes and various control variables in the design of composite for ionizing radiation shielding. In addition, an attempt was made to highlight gaps in research and draw future scope for further studies. It is expected that this review will give some guidance to the future exploration in the design and application of reinforced composite with respect to ionizing radiation shielding processes.
