That's what I was thinking
I saw a bullseye laid over a map of the greater Cleveland area, over what would happen if a 1 megaton nuke blew in the center. Even though I lived in the suburbs I would've been dead in 2 weeks. Probably with my skin falling off.
I remember my 1st thought was, a 1 megaton bomb? At that time everyone was probably up to 20, 30, 40 at least....
