Radiation dose refers to the amount of ionizing radiation energy absorbed by an object or person. It is typically measured in units such as Gray (Gy) or Sievert (Sv), which help quantify the potential biological effects of radiation exposure. Understanding radiation dose is crucial in fields like medicine, where it is used in radiology and radiation therapy to ensure patient safety while achieving effective treatment. The concept of radiation dose also plays a significant role in nuclear safety and radiation protection. Regulatory agencies set guidelines to limit exposure for workers and the public, ensuring that doses remain within safe levels. Monitoring radiation dose helps prevent harmful effects, such as increased cancer risk, from excessive exposure.
