The risk of a radiation-induced fatal malignancy (total body exposure 5%/Gy) for a medical administration of radiation must be considered as very low in comparison to the natural risks. The radiation tolerance of normal tissue structures regarding the induction of functional deficits shows great variation but always has a threshold value, which is usually not exceeded in diagnostic procedures. Various factors (R) influencing the clinical manifestation of radiation effects have been identified related to the exposure pattern. The effects of radiation on tissues are classified into early and late and their pathobiology is significantly different. ![]() The time course of the reaction of tissues to radiation exposure extends over wide ranges up to many decades. This article examines the biological mechanisms at the tissue and molecular level, the clinical manifestation of radiation effects, dose-dependence of the risk and the temporal progression as well as influencing factors. ![]() ![]() Knowledge of the biological mechanisms underlying these effects is essential for individualization of the application. Diagnostic or therapeutic exposure to ionizing radiation can result in tissue changes and tumor induction in the long term. The therapeutic application of irradiation is highly effective against cancer however, this implies exposure of normal tissue structures to significant doses of radiation. Exposure to ionizing radiation for diagnostic purposes is inevitable in modern medicine. ![]()
