Genetic radiation effects involve damage to which cells?

Genetic radiation effects are about heritable changes—mutations that can be passed to offspring. That happens when germ cells, the sperm and egg, incur DNA damage. Because germ cells contribute genetic material to the embryo, mutations there can be inherited by future generations. Damage to somatic cells, like blood or muscle cells, causes effects in the irradiated individual but isn’t passed on to children. So the reproductive germ cells are the ones involved in genetic (heritable) effects.
