Answer:
That"s a new one on me- Atoms can split- with usuallly humungous destructive effect- but I have never heard of a radiation miscarriage, though I am sure it can happen. It has been found crewmen who serve too long in the reactor compartments on Atomic subs- and these operate ( buttoned-up) for 90 day patrols) have shown symptoms of sterility. Naturally there are limits on how much sub duty the crewman can serve- and to some extent the problem can be ameliorated by remote controls- generally placing the reactor room (Off limits) in normal duty hours. This is another argument against Waves on submarines!
