Description/Abstract:
FALLOUT MEASUREMENTS WERE MADE DURING SHOT FIG [ ] TO DETERMI NE MILITARY SIGNIFICANCE OF FALLOUT CONTAMINATION FROM SMALL-YIELD [ ] FISSION WEAPONS. RESULTS INDICATE THAT, WHEN THE SCALING T ECHNIQUES IN TM 23-200 (1957 EDITION) ARE EXTENDED TO [ ] GROSS OVERESTIMATES OF DOWNWIND EXTENT ARE MADE FOR H+1 HOUR INTENSITIES OF 100 R/HR OR LESS. A DYNAMIC CLOSE-IN FALLOUT MODEL IS PRESENTED FOR YIELDS OF 1 TO 100 TONS, WHICH ACCOUNTS FOR GROWTH AND DRIFT OF THE CL OUD DURING ITS RISE AND IS CONSISTENT WITH FIG MEASUREMENTS OF CLOUD S HINE AND AMOUNT OF ACTIVITY DEPOSITED TOGETHER WITH DOSE-RATE INTENSIT Y AS FUNCTIONS OF DOWNWIND DISTANCE. CALCULATIONS USING THIS MODEL AR E MADE FOR [ ] WINDSPEEDS OF 5, 15, AND 30 KNOTS. INTENSITIE S GREATER THAN 100 R/HR SHOW AN INCREASE, WHEREAS INTENSITIES LESS THA N 100 R/HR SHOW A DECREASE IN DOWNWIND EXTENT WITH DECREASING WINDSPEE D. HOWEVER THE 100-R/HR INTENSITY WILL EXTEND NO FARTHER DOWNWIND THA N 600 TO 700 FEET [ ]. THE FEW MEASUREMENTS OF PLUTONIUM CONT AMINATION INDICATE THAT NO SERIOUS LONG-TERM PROBLEM WILL RESULT FROM THIS SOURCE AFTER THE NUCLEAR DETONATION OF A SMALL-YIELD FISSION DEVI CE.
