Somewhere on my bookshelves there is a US Government tome entitled The Effects of Nuclear Warfare dating from 1962. It has some rather unamusing information regarding survival prospects, including a nifty little pull out calculator to calculate blast areas based on megatonnage. It's a rather sobering tome.
If you want rather thought provoking film that utilises most of the nuke survival docos of the time, search for a copy of The Atomic Cafe, excellent film and a wonderful soundtrack to boot.
