SLIDE 4 BRAVO fallout patterns based on meteorology. This contour of exposure rate was estimated by the Armed Forces Special Weapons Project (AFSWP). The contour was cucumber shaped. Exposure rates were hypothetical values at one noe after the shot. The contaminated region was an area of more than 70,000 (27,000 square miles) extending 50 km (30 miles) upwind and over 540 em (340 niles) downwind. The width of the crosswind direction was variable, the maximum being over 220 km (140 miles).
