Radiation protection refers to the measures taken to safeguard people and the environment from harmful effects of ionizing radiation. This type of radiation can come from natural sources, like cosmic rays and radon gas, or from man-made sources, such as medical imaging and nuclear power plants. Effective radiation protection involves limiting exposure time, increasing distance from the source, and using shielding materials. Key principles of radiation protection include time, distance, and shielding. By minimizing the time spent near a radiation source, maintaining a safe distance, and using barriers like lead or concrete, individuals can significantly reduce their risk of radiation exposure. These practices are essential in various fields, including healthcare, industry, and nuclear energy.
