Explosions that create shock waves can do damage according to
the "overpressure" which is reasonable to measure in psi (and
decreases like 1/r^2 from the center of the blast, I think).
An explosion expands in a sphere so I would expect
it to decrease ~1/r^3.
Yes, except if the target and detonation are on the ground then the
wave
reflects off the ground and adds to the wave strength. Also for
damage,
flying objects can be more damaging than the compression wave itself.
