I'm not exactly sure what you mean by that, but radiation-induced deformities are not passed down through the genes. If a woman is pregnant during the exposure, then there is a strong possibility of fetal damage, but survivors of Hiroshima/Nagasaki, for example, didn't go on to have deformed children because of their exposure to radiation.
Apparently you missed the episode of Gilligan's Island where Gilligan found radioactive vegetable seeds.
Why have the Ukranians keep the zone around their reactor free from human habitation?
We really do not know what will happen to folks around the disaster zone in Japan.
Why not serve the wild boars in Japan as a main course.
