“…Theoretical simulations have been carried out to investigate lightweight materials for attenuation of gamma and neutron radiation where multi‐layers assemblies of the Fe‐Interlayer‐Pb represented outstanding shielding performance 25 . Similarly, polyester composite comprising varying proportions of lead iodine were studied for its shielding properties and validated by comparing the results of theoretical transport code 26 . The radiation shielding clothes with use of lead and non‐lead materials have been studied for application in dental clinics and hospitals for protection of workers and patients from unintentional exposure 8 .…”

Radiation shielding composites of ethylene‐propylene diene monomer (EPDM), reinforced with tungsten (W) and barium sulphate (BaSO4) in different filler weight (wt%) were synthesized. The effects of W and BaSO4 on gamma and neutron attenuation properties of the composites were studied by experimental methods using 137Cs, 60Co and 252Cf radioactive sources. EPDM composites with W and BaSO4 fillers were also investigated for filler dispersion using scanning electron microscopy and X‐ray radiograph. The experimental results revealed that the incorporation of W and BaSO4 significantly improved the radiation attenuation properties of the EPDM composites. It was observed that the attenuation properties of the composite material increases with higher concentration of the filler. The half‐value layer (HVL), tenth value layer thickness and relaxation length of the composites were found to decrease with increasing concentration of the filler. The results also showed that the attenuation behaviour of 50 wt% BaSO4 filled polymer composite is comparable to that of the composite with 25 wt% W. The developed composite with 75 wt% W filler exhibited the maximum radiation attenuation with lowest HVL thicknesses.

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

2021

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.

“…31 Recently, research institutes and scientific groups have reported that various polymer matrices can be used for radiation shielding applications, such as boron/polyethylene modified polymer composites, 10 lead monoxide incorporated polymer composites, 32 light-weight bismuth nanoparticles based polymer composites, 33 lead (II) chloride modified polymer composites, 34 boron and wolfram carbide filled polymer composites, 35 lead modified polymer composites, 36 nanosized lead FRPC, 37 silicon polymer composites, 38 lead oxide polymeric nanocomposites, 39 niobium incorporated polymer composite, 40 lead (II) added polymer composites. 41 Although base materials used to prepare polymer composites possess necessary electrical properties and are excellent insulators; however, this property can be enhanced by incorporating micro/nano-sized filler materials as they impart special properties to the resins, reduce cost, and decrease thermal strains due to the variations in the coefficient of thermal expansion. 42,43 However, increasing the amount of filler materials may also increase the cost of composites, especially in resourcedeficient countries.…”

In this study, polymer/glass fiber fabric‐based nanocomposite plates were fabricated with 0.01%–0.1% single‐walled carbon nanotubes (SWCNTs) and filler materials (barite, magnetite, and colemanite) using a hand layup process. Mechanical properties (e.g., tensile strength, flexural strength, and Charpy impact strength), thermal conductivity, and radiation shielding properties (e.g., gamma radiation and neutron radiation) of the specimens were determined. The results revealed that the specimens containing barite and magnetite managed to exhibit adequate mechanical properties (especially Charpy impact strength). Among different filler materials used, barite‐filled specimens outperformed colemanite and magnetite‐filled specimens in terms of mechanical properties. The mechanical performance of filler‐modified specimens can be further enhanced by adopting efficient dispersion techniques to disperse filler material and SWCNTs throughout the composite plates. The thermal conductivity of barite, magnetite, and colemanite‐filled specimens (with/without SWCNTs) increased by 30.56%–60% as compared to specimens only containing SWCNTs and neat polymer, which avoids the accumulation of heat required for radiation shielding applications. Similar to thermal conductivity, specimens containing filler materials (with and without SWCNTs) provided higher gamma and neutron radiation shielding properties as compared to neat polymer‐ and SWCNT‐modified specimens. In the case of gamma and neutron radiation shielding, barite‐ and colemanite‐filled specimens provided better results, respectively.
