“…Numerous studies reported metallic shielding aluminium composites reinforced with B 4 C has good modulus good melting point, high hardness, good tribological and impact properties and possess good chemical resistance [18]. Moreover these materials can absorb effectively the fast neutrons and thermal neutrons from a wide range of neutrons owing to the high neutron absorption cross-section of Boron thereby enabling the material as a neutron absorber for wet storage pools and dry storage casks as well [15].…”

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.

Here we report the syntheses of polyimides with meta-carborane cages embedded in the polymer chain and their characterizations. Aromatic carborane diamines were prepared by a Sonogashira reaction in the first place; reaction of the obtained diamines with commercially available dianhydride led to the formation of carborane polyimides with high molecular weight. Thermogravimetric analysis (TGA) of the samples showed that they have excellent thermal stability, with 5 wt% decomposition temperatures (T d5% ) higher than 520 C. Due to the boron-rich nature of the obtained polyimides, samples prepared here have potential applications in the aerospace industry and nuclear power stations as building blocks for neutron shielding and detecting devices.

“…The domain of application of nuclear technology has been expanding rapidly. As a result, the environments in which shielding materials are used are becoming increasingly harsher [5]. The effectiveness of radiation shielding is subject to strict rules and standards, and there are corresponding requirements for the mechanical properties and heat resistance of the shielding material that must be met [6].…”
