Brief
Discover how advanced concrete mixtures improve radiation shielding for photons and neutrons in nuclear and medical environments.
Insight
Concrete is a widely used material for radiation shielding due to its affordability, versatility, and effectiveness. However, its sprotection against phielding capacity can be significantly enhanced by modifying its composition. Recent research highlights how advanced concrete mixtures improve hoton and neutron radiation, making them vital for use in nuclear reactors, medical facilities, and radioactive waste storage.
The study tested 15 different concrete mixtures, evaluating their ability to block radiation and absorb fast neutrons. High-density materials such as barite and iron proved most effective against photon radiation, while concretes with high iron content, like Iron-Portland (IP) and Ferro-phosphorus (FP), excelled in neutron shielding.
Hybrid mixes, like Luminite-Colemanite-Barite (LCB), balanced protection against both types of radiation, making them ideal for environments with mixed radiation exposure.The findings reveal that composition and thickness are crucial for optimising radiation shielding.

Hybrid formulations provide comprehensive shielding, addressing the unique demands of facilities handling mixed radiation sources, such as nuclear reactors and spent fuel storage sites.By offering practical insights into optimised concrete formulations, this research aids in designing safer shielding solutions, ensuring enhanced protection in critical applications.
Facilities can now tailor concrete shielding to meet specific needs, prioritising safety and effectiveness.
