Radiation protection is the academic field and applied discipline concerned with the principles and methodologies for minimizing the detrimental effects of ionizing and non-ionizing radiation exposure on humans and the environment. It investigates the biological interactions of radiation, develops strategies and technologies for dose limitation through techniques such as shielding, distance, and time optimization, and establishes the fundamental principles and regulatory frameworks (like justification, optimization, and dose limits) necessary to ensure safety in contexts involving radiation sources. Its significance lies in safeguarding health and environmental integrity across various technological, medical, industrial, and natural settings.
