-===== Dose estimate in radiation emergencies and epidemiological studies ​ ===== +
- +
-EPR can be used to identify exposures occurred during accidental nuclear and radiological events (radiological equipment malfunctions or harmful use of ionizing radiation) when conventional personal dosimeters are absent or inadequate. Radio-induced defects on everyday objects such as clothing or screens of mobile phones, or on biological tissues such as nails or teeth, can be used as indicators of accidental exposure and, through the use of calibration curves, as an instrument of evaluation of the absorbed radiation dose. +

-Reconstruction of the individual dose finds application in: +
- +
-  * the assessment of the risk of radiation in individuals exposed to accidental events to prevent their harmful effects and provide any necessary medical treatment;​ +
-  * the estimation of radiation risk factors through the study of epidemiological cohorts in which the health effects are related to the absorbed dose values. +
