• Involves implementing safety measures, optimizing procedures, and using protective equipment.
• Encourages continuous improvement in radiation safety practices.
• Based on the principle that any exposure to radiation carries some risk.
• Promotes the use of time, distance, and shielding to reduce radiation exposure.
• Frequently applied in medical, industrial, and nuclear power settings to protect workers and the public.
• Part of regulatory requirements and guidelines set by organizations such as the International Commission on Radiological Protection (ICRP).
