Lead doors, also known as radiation shielding doors or anti-radiation doors, are functional doors specifically designed to shield ionizing radiation (such as X-rays and gamma rays). As a critical safety barrier in hospital radiology departments, nuclear medicine departments, industrial flaw detection rooms, and research laboratories, lead doors, through high-purity lead plate filling and precise structural design, effectively attenuate high-energy radiation, ensuring the safety of medical staff, patients, and the surrounding environment.
