As an exanple of the complex radiological situation wept axists on
Eniwetok, one {sland - Runit - is shown in Figure 6
with a plot of gamma
exposure rates on that island. Contamination fron
t tests on Runit
is measurable today. An early preliminary survey
confirmed the
presence of a plutonium bearing sand layer cutcrogping on the ocean side
of the fsland, and the existence of solid plut
bearing chunks,
grains, and other particulates on the island syrface and near surface.
Earth and debris moving activities during
after test operations
have resulted fn a complex rediological sityétion in which adjacent
areas may be quite different as to levels
ghd vertical distribution of
radioactivity in soil. Data available to/date indicate that radiological
contemination is less severe on other is
s but is sufficient to pose
a considerable problen.

To date the DOD has
