Radiation dose is a measure of the amount of ionizing radiation absorbed by an object or person. It is typically measured in units such as sieverts (Sv) or gray (Gy). The amount of radiation dose received can have varying effects depending on the type of radiation, the duration of exposure, and the sensitivity of the individual or organism. Research in radiation dose focuses on understanding the potential health risks associated with exposure to radiation, developing methods to accurately measure and monitor radiation dose, and implementing strategies to minimize radiation exposure in various settings such as medical imaging, nuclear power plants, and space travel.
