The main idea is that somatic radiation effects affect the body of the person who was exposed and do not get passed on to offspring. Somatic cells are all the body's non-reproductive cells, so damage there stays with the irradiated individual and doesn’t alter the genetic material that would be inherited by the next generation. For an effect to be heritable, the germ cells (sperm or eggs) must be damaged, which could transmit genetic changes to children. So, the reason this question’s correct answer is “no” is that it’s specifically asking about somatic effects, and those do not become inherited.

The other statements don’t fit this context: saying inheritance occurs may reflect germline mutations, but that’s about germ cells, not somatic tissues. Saying inheritance only at very high doses isn’t the key distinction—the inheritance question is about which cells are affected (somatic vs germ), not just the dose.
