damages living tissue and when deciding whether an should take place, we have to weigh up the to the patient from radiation against the potential benefit of having the exposure. Radiology involves striking a balance between and risk for the patient. The benefit is successful and treatment. The risks are radiation-induced in the individual and serious effects in descendants. When applying the principle of , the benefit to the patient of having the exposure must outweigh the risks. A criterion that is often applied is that the exposure is if the result of having the examination will change the clinical management of the patient.
