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
hoyr after the shot.
The contaminated region was an area of more than 70,000
km”
(27,000 square miles) extending 50 km (30 miles) upwind and over 540 km
(340 miles) downwind.
The width of the crosswind direction was variable,
maximum being over 220 km (140 miles).
