Biodosimetry is the scientific field that involves measuring and analyzing the biological response to ionizing radiation exposure. This field is important for assessing the level of radiation exposure in individuals, particularly in the event of a nuclear incident, radiological emergency, or radiation therapy treatment. Biodosimetry techniques can include assessing chromosomal damage, gene expression, protein levels, and other biomarkers to determine the level of radiation exposure and its potential health effects on individuals. This information is crucial for providing appropriate medical treatment and determining long-term health risks for individuals exposed to radiation.
