Something that I've found to be very useful is to have 2 radii instead of 1. You have an inner and outer radius that the designer can set.
Anything inside of the inner radius is affected at full strength and anything outside of the inner but inside the outer is affected with linear falloff (starting from the edge of the inner radius).
Check out UnrealEd for a working example to see it in action. It really works nicely.
