Anyone forced to go outside to find drinking water over the first few weeks have pretty poor odds, if the water contains fallout.
it really depends on the choice of warhead and in a worst-case scenario I do get to life for a few more days. But I had previously seen data for a Hiroshima-sized bomb and considered my chance of survival to be quite good. Turns out that yield class isn't really part of the discussion anymore.
