Well, considering worst case (best case is you die without ever knowing) is Total Civilization Death:

Stay in place, indoors, and underground. Do not breathe or come into contact with anything from the outside (rain or dust or particles).

Once the first few days (and rains) are over it should be safe to go outside, by which I mean you're going to die of starvation or a badly infected tooth long before the cancer any residual radioactivity could give you. By all means if you want to keep playing medieval-style peasant for the remaining years you have left, go for it, but I would recommend just going on a tourist hike, see some cool post-nuclear scenery, and call it a night with a good bottle of alcohol and a bullet.
