AERB registration, managed by the Atomic Energy Regulatory Board in India, is a vital regulatory process for entities using ionizing radiation, nuclear materials, or operating nuclear facilities. It ensures that these organizations adhere to stringent safety and security standards to prevent radiation-related accidents and unauthorized access to nuclear materials. The registration process includes a thorough evaluation of safety procedures and infrastructure, ensuring compliance with national and international regulations. Regular inspections and audits are conducted post-registration to maintain safety standards. AERB registration is essential for safeguarding public health, the environment, and national security by overseeing responsible nuclear technology use.
