Operation TUMBLER, Pre-Shock Dust, Project 1.9
Abstract
The objective of Project 1.9 was to determine the concentration and the particle size distribution of the pre-shock dust generated from the surface of the ground by air currents resulting from the incidence of thermal radiation on the surface of the ground. Cascade impactors and filter samplers were used to sample pre shock dust for the brief period of time between the time of detonation and the arrival of the shock wave at the station. The following conclusions are drawn: (1) The presence of pre-shock dust in concentration of from ten to several hundred times background has been established. (2) There was no significant difference between the particle size distribution of pre-shock dust and background dust. (3) Little variation in dust concentrations from shot to shot was shown.
