Distribution and characterization of fall-out and airborne activity from 10 to 160 miles from Ground Zero, Spring 1955
Technical Report
·
OSTI ID:6670302
Fall-out patterns of four tower shots were delineated by survey-instrument methods to distances of approximately 160 miles from Ground Zero. Surface-contamination levels in terms of ..mu..c/ft/sup 2/ and fall-out particle-size distributions were determined by soil-sample analyses. Airborne radioactivity concentrations determined by air samplers of different types and supports agreed within a factor of 4; aerosol radioactivity median diameters of < 5 ..mu.. were determined by cascade impactors. The solubilities of fall-out and airborne radioactivity in 0.1N HCl ranged from 20 to 30 and 65 to 85%, respectively. More than 90% of the fall-out from two shots was magnetic. Beta-decay slopes ranged from T/sup -0/ /sup 80/ to T/sup -1/ /sup 59/, and field gamma-decay slops ranged from T/sup -1/ /sup 07/ to T/sup -2/ /sup 10/. Principal beta-energy peaks of 0.6 and 2.0 MeV were observed.
