Dust clouds from seven high-explosive detonations ranging from 20 to 500 tons in the Middle Gust-Mixed Company series were sampled using various aircraft-mounted instruments. A wet cyclone system proved to be the best device for sampling airborne dust. Dust concentrations as a function of time and location in the clouds were determined. One cloud was underflown as early as Z 122, and another was entered at Z 136. Fallout was measured on three tests, and various experiments were conducted to detect sweepup of dust from outside the crater zone. Gas samples were collected and analyzed from inside the 500-ton Mixed Company III cloud. Selected airborne dust and fallout samples were sized using an optical image processing computer. Density measurements were made to determine if particles expanded or melted in the fireball. Author
