As an exampla of the complex radiological situation which exiats en
Enivwetok, one island, Runit, fis shown in Figure 6 with s plot of gamma
exposure rates on that {sland. Contamination from eight tests on Runit
is measurable today. An early preliminary survey has confirmed the
presence of s plutoniumbearing, sand layer outcropping on the ocean side
of the faland, and the existence of solid plutoniue-bearing chunks,
grains, and other particulates on the island surface and near surface.
Rarth and Gabris moving aetivities during and after test operations
have resulted in a complex radiological aftuation {n which adjacent
areas may be quite different as to levels and vertical distribution of
radioactivity fn sof]
Data available to date indicate that radiological
contamination fe less severe on other {slands but is eufficient to pose
a considerable problem.
At a September 7. 1977, Interagency Meeting, the following agreements
with respect to unding were raachad
(a)
The ABD will fund the radiological aspecta of the
precleanup survey, the conduct of any other radtological
wurvey activity that might be required to undaratand
conditions in the environment as they relate to axposures
of people and developmenta of: eatandards, and the conduct
of periodic follow-up radiological surveys that take place
after cleanup.
If later field and/or laboratory work is
done by the AKC in suppert of cleanup, AEC should be reimbursed
by DOI
(>)
DOD would be responsible for funding the engineering portions
of the precleanup survey and those monitoring and eurvey
activities that are required tc support cleanup operations
and to insure safety ef personorel involved in cleanup
activities.
DOD also would func the later cleanup of both
radiological and non-radiclogical activities. DOI would be
responsible for funding retabi {tation costs once cleanup fe
completed
Present best estimate of the cost of the AEC precleanup radfological
survey is $1.3.
Coste ef subsequent studies and radiological
monitoring activities ere estimated to be approximately $1! per year
for FY 1974 anc beyond. DOD costs for cleanup and related activities
are estimated at between $20-4@: end may go higher. The actual final
costs are highly dependent on the amount of sofl and debris needed to be
removed and subseauent disposal matbods employed. To date the DOD has
committed approximately $5O0K in the preclaanup engineering survey.
