“…Numerous studies focused on the B 4 C content in the shielding material in order to confirm the suitability in the nuclear shielding applications. It was also reported by researchers that increase in B 4 C content tends to increase the neutron shielding ability of the material [22]. Moreover increase in the mass fraction of B 4 C was reported as an aid to increase the hardness of the material however that deteriorates the toughness of the material and therefore the fraction is restricted utmost to 30% in order to avoid degradation of mechanical properties [24].…”

“…Moreover the growth in the shielding properties was reported with incremental trend upon adding other heavy metals as minor additions with PbO [48]. Researchers earlier revealed the limitations of using carbon fiber with polymer matrix owing to low bonding ability and low surface energy [16,22]. On the other hand subjecting the material to suitable surface treatment techniques could overcome the above limitations and reported to develop irradiation shielding ability of the material.…”

Ionizing radiation finds its part in a wide spectrum of fields such as medicine, industry and research. These radiations in the form of alpha, beta, neutron particles, gamma and X-rays are very dangerous for not only humans but also for biotic and abiotic environments. The present article briefly works out the irradiation shielding ability of some potential composite materials to recognize the shielding tendency and enabling the same to find some promising applications in defense as well as nuclear research. The physics of irradiation decay and shielding is appraised in this critique. This review article studies about various materials employed for the attenuation of nuclear radiations and their response in terms of attenuation rates (I/I0 ) after exposure to the radiation. The study also focuses on the mechanical performance of the shielding materials meticulously for the application of dry storage of the spent fuel possessing a potential threat of radiation hazards. Moreover the evolution of composite materials in the structural applications is contemplated.

The nature and properties of neutron radiation impose specific requirements on the creation and operation of such materials. The presence of accompanying and induced radiation, weather conditions, as well as the peculiarities of the location of functional layers require a hierarchical approach to the development of such neutron-absorbing materials. It was shown that the conceptual scheme of creating Gd-containing protective materials consists in taking into account all factors of their operation. In particular, it is shown that the presence of neutron-absorbing components is a necessary but not sufficient condition for their successful application in environmental conditions. In this work, Gd-containing chitosan films were prepared as an example of the proposed conceptual scheme for the creation of environmentally friendly neutron-absorbing nanocomposites. The prepared Gd films were characterized and their neutron permeability was estimated. The approach presented in this work contributes to the development of sustainable and responsible production practices, supporting SDGs 9 and 12.

“…11 That is, neutron shielding materials require substances with large neutron absorption cross sections such as boron and heavy metals to attenuate secondary γ-rays. 12 Therefore, developing wearable articles bearing heavy metals and boron-containing substances is of vital importance to the radiation protection safety of human being in complex radiations. 13,14 Great achievements have been made focusing on rubberbased composites for wearable articles.…”

Developing wearable articles with radiation protection safety and wear comfort in complex radiations is one of the urgent issues because flourishing nuclear technologies lead to increasing radiation threats. However, current wearable articles either shield neutrons or γ-rays or display poor permeability of air and water vapor and so on, which leads to difficulty in satisfying the requirements of complex radiations. Herein, surface modification techniques are applied to construct sufficient hydrogen bonds between functional particles (B 4 C and PbWO 4 ) and PVA matrixes for intensifying the interface interaction, which facilitate the smooth wet spinning of as high as 50 wt % B 4 C/ PVA and 70 wt % PbWO 4 /PVA fibers under an exclusive pilot line for large-scale preparation. Then, both of the highly filled PVA fibers are woven into two kinds of fabrics that are overlapped for multilayer fabrics. They jointly shield neutrons and γ-rays while giving good permeability of air and water vapor. The overlapping two-layer B 4 C/PVA and two-layer PbWO 4 /PVA fabrics are provided with 72.90% thermal neutron adsorption (0.025 eV) and 38.62% γ-ray attenuation (105 keV). In addition, they also display 155.88 mm/s and 2536.37 g/m 2 •24 h air and water vapor permeabilities, respectively. Besides, good flexibility of the fabrics is not sacrificed in spite of the extremely high loading of functional particles in PVA fibers. This work provides a feasible approach to deal with the challenge of radiation protection safety and wear comfort of wearable articles in complex radiations.
