Watch the Dogbone BANG run <https://www.youtube.com/watch?v=dDfRaDY2R_A> in HD to see these data points.
Geiger counter readings: 6:14:13, 8e-6 6:16:46, 9e-6 6:17:15, 3.3e-4 a few seconds later BANG The pressure went down initially from 0.7 to 0.5 the back up to 0.9 but at no point did the "PSI" exceed 1.0 so if that was measuring the build up of gas pressure energy, there wasn't enough to do anything like what we saw. It might have been a rapid conflagration of LiH coming in contact with atmospheric O2 if there was a breach just prior to the BANG but there was no indication of such a breach that I could see.
