PREDICTION OF FALLOUT FROM ROW-CHARGE SHOTS
In principle, the fallout pattern from a row of subsurface nuclear
detonations may be estimated with the crate::ng fallout model, provided the model input parameters are adequately known for 1row-charge
events. In the current state of knowledge, the cloud-geometry input
parameters and the value of F, appeartobe the most difficult to specify.
Study of time-lapse photography of the main-cloud and the base-surge
evolution from past high-explosive row-charge tests give significant
experimental information on the cloud~geometry parameters. For example, empirical methods of predicting crosswind radius and height of
the base surges originating from high-explosive row-charge shots have
been studied.’ In this study it was shown that for five equal-weight
charges, equally spaced and emplaced at the same depth of burial, the
