“…Different barite concentrations 0%, 10%, 20%, 30%, 40%, and 50% were added to epoxy, and the linear attenuation coefficients of the composites increased with the increase in barite concentrations (Al-Sarray et al 2017 ). Styrene-butadiene rubber (SBR-1502)/montmorillonite nanocomposites in the presence of ferric oxide (Fe 2 O 3 ), zinc oxide (ZnO), molybdenum oxide (MoO), and titanium dioxide (TiO 2 ) were synthesized to investigate their effectiveness in shielding against gamma radiation.…”

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.

“…Although there are three ways for the radiation protection, the shielding of radiation is the most commonly used method. Many different studies on the linear attenuation coefficient for different materials can be found in [2]. With the increasing application of gamma radiation in industry, medicine, agriculture, nuclear reactors, and particle accelerators, the shielding becomes of a paramount importance in order to use this radiation without a risk.…”

Low-cost polymer nanocomposites prepared for the nuclear radiation shielding have highly linear attenuation coefficients, light weight, and elastic, good mechanical, optical, and dielectric properties. The carboxymethyl cellulose (CMC)–polyvinyl pyrrolidone (PVP) polymeric blend is prepared with concentrations: 60 wt.% CMC and 40 wt.% PVP. The lead oxide nanoparticles are added to the CMC–PVP blend with different concentrations: 0, 2, 4, 6, and 8 wt.%. The structural and optical properties of (CMC–PVP–PbO2) nanocomposites are studied. The results show that the absorbance of the (CMC–PVP) blend increases and the energy band gap decreases, as the concentration of PbO2 nanoparticles increases. The optical constants of the (CMC–PVP) blend increase with the concentration of lead oxide nanoparticles. The (CMC–PVP–PbO2) nanocomposites have highly linear attenuation coefficients for gamma radiation.

“…40 keV showed that composites with 10% of ZrO2, and only 1.0 mm thick, can attenuate 60% of the x-rays beam. Al-Sarray et al [111] in a similar study, produced polymeric composite materials and measured their radiation shielding properties. Barite was used in different rates of 0%, 10%, 20%, 30%, 40%, and 50% as reinforcement in the epoxy composite.…”

Trends in reinforced composite design for ionizing radiation shielding applications: a review

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.
