Preparation of flexible ceramic-rubber composite for hybrid gamma and neutron radiation shielding

Fabrication of flexible and light materials that successfully protect radiation workers and the environment from high-energy gamma and X-rays has already been accomplished in various practical applications. Conformability, cost-effectiveness, weight factor, toxicity, durability, and other factors must all be considered when selecting an appropriate shielding material. X-ray and gamma radiation, which may be protected by high density materials like cement, lead, and bismuth, is the most frequent ionising radiation type employed in many applications. Shielding materials for neutrons, on the other hand, are mostly depending on the kind of neutron source, its power, and the application type. Many investigations have been conducted on the neutron radiation shielding properties of materials generated primarily by the integration of hydrogen-rich elements. The present emphasis of industry and academic organisations is on producing neutron shielding materials. Because of tuneable elasticity, natural rubber (NR) can be considered as a promising candidate for neutron and gamma shielding material. Some research suggests that combining metal ores and aggregates with rubber may improve the flexibility, gamma absorption, and neutron shielding capabilities of the material. When constructing bio filled polymer composites, good filler-matrix adhesion, high modulus, low stress, low moisture absorption, high durability, and longer life length are all factors to consider. Ceramics and coconut shell may be used as a filler in biodegradable polymer composites because of their greater mechanical strength and thermal stability when compared to other agricultural wastes. The current proposal focuses on the development and testing of a series of rubber basted ceramic composites (heavier than wax) that would efficiently decrease shielding thickness and improve the shielding ability. The characteristics of the shielding material must be investigated in the thermal, epithermal, and fast neutron regions, as well as the prompt gamma yields
