Hi could someone tell me a little more about shockwaves? I have looked everywhere but cannot find anywhere that shows explosive yield to blast radius and the dangers to human of being at different proximities to a blast. I know the closer you are to one the more likely you are to suffer internal injuries from the wave slamming into your body. Could really do with a chart or diagram displaying the various zones. Also could someone tell me if a shockwave travelling through atmosphere can carry on at the same strength if it encounters a vaccum? Just to put minds at rest im interested in protection from shockwaves not causing one myself! Thankyou in advance.
