Bishop, J A; Lowance, F E

A study was made to determine the physical dimensions of the craters and lips resulting from the surface (S) and underground (U) explosions. Soil samples were taken to establish the characteristics and properties of the soil within the anticipated U burst crater area. Topographic surveys were made before and after the blast of the areas surrounding the zero points and the quantities of earth moved were estimated. An attempt was made to establish the true crater depth resulting from the U burst by measuring the amount of radioactive contamination obtained from the surface to a depth of two feet. The maximum depth of the U burst crater was approximately 53 ft and the width was approximately 258 ft. The maximum height of the lip above original ground surface was 8 ft. The S burst crater was approximately 17 ft in depth and the lip S ft above original ground surface. The width of the crater was approximately 90 ft. A radioactive gradient in the soil on the sides and in the bottom of the crater of the U burst was plotted. (D.L.C.)
