My mother was born in December of 1946. She was the first child of a man (my grandfather)who was in the Pacific until late 1945. I never heard from anyone that there was a stillborn child. Then again, knowing what I do working in a radiation area (fluroscope), male gametes respawn in about a month, therefore the radiation probably only really affected those who were there in August, went home in August and "got some." Those were probably the children who were stillborn.
