Abstract
The efficiency of radiation shielding is crucial across industries having radioactive activities, from medical facilities to nuclear power stations. Radiation-Shielding Concrete (RSC) emerges as the preferred material for its cost-effectiveness, robust mechanical performance, ease of production, and excellent radiation attenuation properties against ionizing radiations such as gamma rays, X-rays, and neutrons. This comprehensive review delves into the evolution of SCI indexed research on concrete materials for radiation protection, focusing primarily on studies published in the last decade. It meticulously analyze the latest literature to understand how RSC materials enhance radiation attenuation. The review provides valuable insights into the influence of irradiation on both macro- and micro-properties, enriching the knowledge base for material efficiency and effectiveness concerning different types of radiation and shielding requirements. Additionally, this review with a set of recommendations for future research to advance progress in modern construction, encouraging further examination and innovation in the selection of RSC materials. • The effectiveness of various materials in Radiation-Shielding Concrete (RSC) production has been identified and analysed. • The impact of irradiation on the micro and macro properties of concrete has been thoroughly explored. • The mechanisms of interaction between irradiation and cement hydrates, along with their multi-scale effects, have been reviewed. • The influence of irradiation in inducing Alkali-Silica Reaction (ASR) has been explored. • The key future research needs for enhancing RSC have been identified.
