‘The presentation was aided by a large number of "height of burst
charts" for the various weapons effects.
Some of the points brought.
out were the following: There is a "bonus factor" in the sealed
effects (on a light steelframe structure, for example) of 1 MT versus
these of 1 KT, due to the longer wind duration with the higher yield
explosion,
Against aircraft, dynamic pressure and penetrating radia~
tion effects seem the most important. (For a 2 KT shot against a B-29_
at 10,000 ft the 5000 r radiation envelope reaches out farther than
the thermal and wind effects, except in certain directions in which
the last have a greater lethal range.
At 40,000 ft radiation has a -
larger lethal radius than any other effect.)
With respect to surface
contamination, induced activity predoninates over fallout for high
altitude bursts.
