Which statement about genetic risks from radiation is most accurate?

Explanation:
Genetic (hereditary) risks come from mutations in germ cells that can be passed to offspring. If radiation causes DNA changes in sperm or ova, those mutations can be inherited by future generations, not just by the person who was irradiated. Diagnostic doses carry a small but nonzero risk, so the possibility exists even at low levels. The statement that best captures this is that genetic changes may occur in future generations and are not limited to the exposed individual.
