Title: Total mass and concentration of particles in dust clouds

Abstract

The clouds from seven Pacific Proving Grounds nuclear tests and two Plowshare cratering experiments have been sampled to determine the mass loading of the clouds. The average value for the total mass of debris from surface bursts of megaton yield is 0.2 Mt mass/Mt yield; the measured particle concentration in air ranges from 6 x 10/sup -10/ to 7 x 10/sup -9/ g/cm/sup 3/. The mass of debris per unit yield from cratering explosions is about two orders of magnitude higher than is the case for surface bursts, but only a small percentage of the mass is still present in the cloud after a few minutes. The average concentration of dust in explosion-produced clouds is in the same range as the mass concentration measured in naturally occurring high tropospheric clouds.
