As an exampis ef the complex radiological situation which exists on
Eniwetok, one island, Runit, ia shown in Figure 6 with a plot of gama
exposure rates on that island.
is measurable today.
Contamination from efght teste on Runit
An early preliminary survey has confirmed the
presence of a2 plutonius-bearing, sand layer outcropping on the
oce
ocean side
of the faland, and the exfstence of solid pluroniue-bearing chunks
grains, and other particulates on the fsland surface and near surface.
Earth and debris moving activities during and after test operations
have resulted in a eomplex radiological eftuation fn which adjacent
areas may be quite different as to levele and vertical distribution of
radioactivity in sofl.
Data evailable to date indicate that radiological
contamination is less severe on other islands but is sufficient to pose
a considerable probien.
At a Septender 7, 1972, Interagency Meeting, the following agreements
with respect to funding were raached:
(a)
The AEC will fund the radiological aspects of the
precleanup survey, the conduct of any other radiological
survey activity that might be required to understand
conditions in the environment as they relate to exposures
of people and developmente of etandards, and the conduct
of periodic follow-up radiological surveys that take place
efter cleanup.
If later field and/or leboratory work is
done by the AEC in support of cleanup, AEC should be reimbursed
by DOD.
:
(6b)
DOD would be responsible for funding the engineering portions
of the precleanup eurvey and those monitoring and survey
activities that are required to support cleanup operations
and to insure safety ef personnel involved in eleanup
activities. DOD also would fund the later cleanup of both
radiological and non-radiclogical activities, DOI would be
responsible for funding rehabilitation costs once cleanup is
coupleted.
fl
Present best estimate of the eost of the AEC precleanup radiological
survey is $1.3M. Costa ef subsequent studies and radiological
wonitoring activities are estimated to be approximately $1! per year
for FY 1974 and beyond. DOD costs for cleanup and related activities
are estimated at between $20-401i and msy go higher, The actual final
costs ere highly dependent on the amount of soil and debris neaded to be
removed and subsequant disposal methods employed. To date the DOD has
committed approximately $500K in the precleanup engineering survay.
