Without computers, or at home away from the mainframe, we really had slide rules for just about everything you would need to routinely calculate. A lot of them are sponsored or provided by corporations or trade associations, TRW provided the ICBM Effectiveness & Survivability model which looks really useful: https://osgalleries.org/collectors/davis/info_and_image.cgi?string1=nuclear&string2=2079 https://osgalleries.org/collectors/davis/info_and_image.cgi?... Even more handy would be the Ground Zero/Bomb Damage slide rule: https://osgalleries.org/collectors/davis/info_and_image.cgi?string1=nuclear&string2=2089 https://osgalleries.org/collectors/davis/info_and_image.cgi?... This is an outstanding black slide rule and its maker has remained anonymous, it's pretty dark but I guess a bright enough flash of light is expected to be available when you need to do this calculation.
