Ionizing radiation is a form of energy that can remove tightly bound electrons from atoms, which may lead to the formation of ions. This interaction with biological tissues can cause DNA damage, leading to genetic mutations. Such mutations might not only affect the individual but can also be passed on to future generations if they occur in germ cells. The long-term consequences of radiation exposure include an increased risk of developing cancer and hereditary genetic conditions.

In imaging techniques, the benefit of diagnostic information needs to be weighed carefully against the potential risks of exposure to ionizing radiation. Increased lifespan and improved diagnostic accuracy reflect benefits rather than risks. Similarly, reduced treatment efficacy does not directly relate to the effects of ionizing radiation in imaging; rather, it pertains to treatment outcomes and is not a primary concern with imaging techniques. Therefore, the recognition of genetic mutations as a risk emphasizes the need for judicious use of ionizing radiation in medical imaging.
