Direct contamination - Ground samples should be eollected at various
locations around the point ef detonation and subjected to radio-
chemical analysis,
These results should be correlated with
distance from the center and type of surface. Preliminary analyses
of the chemical and physical characterietics of the soil should
be made prior to the detonation in order to correlate them with
the erater characteristics.
