In fact, the mutation rate among the children of Hiroshima survivors is greatly exaggerated and not supported by evidence. According to that article no health effects could be measured in the next generation. Another article: https://k1project.columbia.edu/news/hiroshima-and-nagasaki https://k1project.columbia.edu/news/hiroshima-and-nagasaki Note the distinction mentioned here: children conceived prior to the bombing, whose mothers were pregnant when they were exposed to radiation, did suffer negative health outcomes. Children conceived afterwards have no measurable health impacts from their parents' exposure to the radiation. So the evidence of these various studies seems to indicate that whatever harm radiation exposure causes will not be passed on to the next generation via sperm or egg cells, and we can speculate about the reasons why (error correcting mechanisms, spontaneous abortion in early embryonic development, etc.).
