In terms of the half life of the radiation, it wouldn't make a damned bit of difference.
I thank you for your gracious recommendation of books that could increase my knowledge of nuclear weapons, but I already know all I want to know about these weapons and I didn't gain this knowledge from books. (Well, maybe a few classified manuals.) After Vietnam, I served most of the 1970s on U.S. Army Special Forces SADM Teams and I came away with a good knowledge of these weapons and their capability.
Good day, Sir. I'm done with this thread.
