Re: Wait - you punch WHAT?!? (or what would the damage from an atomic bomb be?)
For our campaigns, we have a simple rule for such situations--we call it the "enough rule". "How much damage do I take?" "Enough." The essence of KISS.
A couple more factors to consider though, folks, if it's Nazi's buying the bomb--is it a WW2 era design? If so--it used a hollow cylinder/plug design, and was NOT sub-critical mass. The conventional explosive was to drive the plug into the hole in the cylinder, thereby achieving critical mass. Therefore, if a brick tried to use the old "pound it flat to disarm" method--and hit it in the wrong spot, it could quite possibly trigger the full nuclear detonation. Time to check for unluck, though I'd recommend that one be a straight GM call.
The other thing to consider is--the soap and water decon is for fallout, not plutonium. The field manual treatment for plutonium contamination is immediate high amputation of the contaminated limb. Plutonium is one of the most deadly substances known to science, and the lethal mass is about the side of a pin head. Even supers wouldn't be casually shrugging that off.
