As an example of the complex radiological #ituation which exists on
Eniwetok, one feland, Runit, ia shown in Figure 6 with a plot of ganme
exposure rates on that feland. Contamination frow eight teste on Runit
is measurable today. An early preliminary survey has confirmed the
presence of a plutoniua-bearing, send layer outcropping on the ocean side
of the island, and the existence of solid plutonium-bearing chunks,
grains, and other particulates on the island surface and near surface.
Earth and debris moving activities during and after test operations
have resulted in a complex radiolegical situation in which adjacent
ereas may be quite different as to lewela and vertical distribution of
radioactivity {in soil. Data available to date indicate that radiological
contamination {s less severe on other islands but fe sufficient to pose
a considerable probles.
At a September 7, 1972, Interagency Hecting, the fo)lowing agreenents
with respect to funding vere reached:
(a)
The AEC will fund the radfiolegical aepects of the
precleanup survey, the conduct of any other radiological
eurvey activity that might be required to understand
conditions in the environment ase they relate to exposures
ef people and developments of standards, and the conduct
of periodic follow-up radiological surveys that take place
after cleanup.
If later field and/or laboratory work {s
done by the AEC in euppert of cleanup, AKC should be reiabursed
by BOD.
(+)
DOD would be responsible for funding the engineering portions
of the precleanup curvey and these monitoring and survey
activities that are required to euppert cleanup operations
and to insure safety of persennel involved in cleanup
activities. DOD alec would fund the leter cleanup of both
radiological and non~radiclegical activities. DOI would be
responsible fer funding rehabilitation costs once cleanup ie
cowpleted.
Present best estimate of the cost of the AEC precleanup rad{elogical
survey is $1.3M.
Costs of subsequent studies and radiological
monitoring 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 620-40: and may go higher. The actual final
costes are highly dependent on the amount of soil and debria needed to be
removed and subsequent disposal methods employed. To date the DON has
committed approxiastely $S00K in the precleanup engineering survey.
