From what I know, there were certain areas that were hit by bombs, important areas to the countries, such as the D.C. area. However, certain areas weren't hit as hard, either only surrounded by missiles or not even a target, Vegas an example. However, you have enough radiation leaking into the air and it will spread, exactly what happened. Plus remember that people surviving and running around are going to loot what they can and freak out, destroying things purposely or accidentally.
The rest of the world does get hit I believe, but as said I'm sure, you're not supposed to know. You're stuck in your one hole and when you emerge you look around, and see what you can see only. You travel around the fellow areas a bit, but there's a lot of areas you'd have to travel to, and the mystery surrounding it helps add to the atmosphere
