Radiation safety is a set of practices designed to protect people and the environment from harmful effects of ionizing radiation. This includes understanding the sources of radiation, such as X-rays, nuclear reactors, and radioactive materials, and implementing measures to minimize exposure. Key principles of radiation safety include time, distance, and shielding. By limiting the time spent near radiation sources, increasing distance from them, and using appropriate shielding materials, individuals can significantly reduce their risk of radiation exposure. Awareness and training are essential for anyone working in environments where radiation is present.
