Sorry if this is the wrong subreddit to ask this, I'm just looking for some scientifically proven facts to back the concept of a book I'm looking into writing. If let's say, North America, was nuked (by a standard sized nuke? Is there a standard size lol?) which people would survive the initial explosion? Would it exclusively be tied to proximity to the blast? Could people in certain locations within the previously established 'kill-zone,' or 'blast-zone,' survive if they were for instance in a bunker/underground/in a particular situation? Also what kind of mutations would arise, and over what time period (for the people that survive that is). How far would the nuclear fallout affect living conditions and what would those conditions include. Thanks!
