Working at a nuclear power plant does not generally cause any health problems, and should not cause any fertility or pregnancy issues. Radioactivity is only an issue for people who actually work with the reactor itself; they've got all kinds of procedures for dealing with it. For the average worker, radioactivity is only an issue in case of an accident, which is exceedingly rare. (And considering the chemicals and such many companies work with, in case of an accident you would probably not be much better off at a different place.)
If you were not armed it would have been alright. but since you are armed I think there is a chance it can affect your unborn children.
