We were discussing this last night.
Apparently:
In a Random Gen (http://7daystodie.gamepedia.com/Random_World_Generation) map, the Nuclear Fallout Zone is present as a barrier at 10k km in a circle around the 0,0 coordinates. This was added in A13 due to bugs happening when you get to far away from the center of the map. You can edit this in the XML's though and still have a truly limitless world.
I'm going to go due south until I hit the alleged boundary then I plan to circle it in its entirety. If my O level maths is correct the diameter would be 20km witha Random Gen map therefore of 314 sqkm
