DISTRIBUTION AND CHARACTERISTICS OF FALL-OUT AT DISTANCES GREATER THAN 10 MILES FROM GROUND ZERO, MARCH AND APRIL 1953
Technical Report
·
OSTI ID:4034063
Detailed studies were made of the fall-out measurements made at distances greater than 10 miles from Ground Zero of Shots 2, 3, 4, 5, and 7 of Operation Upshot-Knothole. Shots 2, 5, and 7 resulted in downwind areas of moderate to high-level contamination, with the maximum contamination occurring at 15 miles from Ground Zero of Shot 7; a field dose rate of 1630 mr/hr and a surface contamination of 18,580 mu c/ft/sup 2/ were observed at this location. Particle-size studies of settled material indicate an inverse relation between median diameter and distance. Empirical relations derived from the data are presented. (D. L.C.)
