Fallout measurements were made on Fig Burst to
determine the range of militarily significance fallout
intensities produced by a 20-ton-plus 10% surface burst

on an extended land mass. For the burst environment of
Fig Burst, intensities greater than 1 r/hr measured at H
+ 1 hour will not extend beyond 2600 ft downwind. Levels
greater than 100 r/hr at H + 1 hour are estimated to
extend less than 1000 ft downwind and 150 feet
crosswind. From data obtained a fallout model will be
constructed which will be used to estimate extremes in
fallout intensity patterns caused by varying wind
conditions and cloud dimensions.
