"DNA... is the most wonderful thing in the world... Mankind went through epidemics, famine, and...trials, yet nature kept this... intact, because all life depends on it. ...[M]an has found a means to damage it. High energy radiation does so. ...There may ...be survivors after after an atomic war, but those... will be unable to produce a healthy progeny. Their progeny will be beset by abnormalities, monstrosities and diseases... and there will be no way back."
