PARTICLE MOTIONS NEAR EXPLOSIONS IN HALITE
Peak particle velocities and displacements are mearured for tamped (coupled) and cavity (decoupled) explosions in halite. Recordings are illustrated of particle velocity versus time in the salt medium and of pressure versus time on the cavity wall. Peak particle velocities from tamped shots decrease as d/sup -1.//sup 65/ over distances equivalent to 40 to 800 feet for 1000 pounds of high explosive. Decoupling factors that are directly observed apply only to close-in stations. One method of extrapolating close-in data yields distant decoupling factors ranging from 40 to 100 for these particular experiments. Actual measurements of distant decoupling factors give larger numbers by a factor of 2. Extrapolation to nuclear explosions is not attempted here. (auth)
