Concussion damage in various Atm. Densities

[Zparkz]

Are there any good way to calculate the concussion damage dependent on atmospheric pressure?

Or does it matter at all?
I use the TNE rules.

For breathable atmospheres, it pretty much doesn't matter.

Concussion forces half in meters of blast radius.
Atmosphere halves in density in kilometers of altitude. Air thin enough to reduce damage is unbreathable.
