ganna field contours were constructed.
This information was obtained
by completely analyzing the wind structure existing at and after shot
time with respect to its effect on fallout particles originating in tae
stem and cloud. To establish a pattern on this basis it was necessary
to make the following assunptions:
(a)
The relative contribution of particles less than 25 4 in
diameter to the residual gamma field defining the area of prinary falla
out was negligible.
The particle size distribution is the same at all eleva(b)
tions and homoeneous throughout the visizle dimensions of tue cloud
and stem. ‘this assumption was arbitrarily chosen as tne best
