SECRET-RESTRICTED DATA
+
The development of very low-yield nuclear weapons and the
evolution of the Davy Crockett weapons system resulted in a requirement
for the experimental determination of the effects of such weapons.
An
extensive effects program was therefore conducted in conjunction with
four test firings of a subkiloton device during the Eniwetok and Nevada
phases of Operation HARDTACK.
The resulting data are correlated and
summarized in this report and realistic troop safety and casualty radii
are presented for yields ranging from 1 to 200 tons.
The experimental data from three subkiloton shots of Operation
ACK indicate that
(a) the initial nuclear radiation is the controlling effect
for the determination of troop-safety distances and casualty radii,
(ob)
the safety distances and casualty radii specified by the
(c)
with the exception of fallout and of blast overpressures
conceptual studies of the Davy Crockett weapons system are realistic,
below 10 psi, the weapons effects of interest agree generally with
extrapolations of data from higher yield detonations.

(U)
Tne purpose of this work was to verify theoretical calculations
that will predict the radiation level above a umiformly contaminated
plane of gamma radiation and serve as the open-field data for later shielding experiments.
Two sources, cobalt-60 and cesium-137, were used to simulate
the uniforrly contaminated plane. The dose rates at various heights above
