. As an example of the complex radiological situation which sxists on Eniwetok, one {sland - Rumit - La shown in Figure 6 with a plot of gamma exposure rates on that island. Contamination from eight tests on Runit is measurable today. An early preliminary survey fas confirmed the presence of a plutonium bearing sand layer outer ping on the ocean side of the island, and the existence of solid plutonfes bearing chunks, grains, anc other particulates on the island surface and neer surface. Earth and debris moving activities during and after test operations have resulted in a complex radiological sityation in which adjacent areas may be quite different as to levels ehd vertical distribution of radioactivity in soil Data available to date tndicate that radiological contamination is less severe on otber (tslande but fs eufficient to pose a considerable prob! em At a September 7, 1972, Interagency Meeting with respect to funding were reached (a) the following agreements The AEC wtil fund the rddiological aspects of the pre-cleanup survey, thé conduct of any other radiological survey activity that ght be required to understand conditfons in the environment as they relate to exposures of people and developments of standards, and the conduct of periodic follow-up radiological surveys that take place after cleanup. Jf Later field and/or laboratory work {s done by the AEC 4n support of r' eanup, AEC should be reimbursed by bor (b) DOD would be responsible for funding the engineering portions of the pre-cleanup survey and those monitoring and survey activities that are required to support cleanup operations and to fneure safety of personne! fuvolved io cleanup activities DOD also woud fund the later cleanup ¢: both radiological and non-raditelogical activities. DOI would be resporaible for funding rehabil{tatiom costs once cleanup is comp let ec Present best estimate of the coat of the AZC pre-cleanup radiological survey is $1.3M Costes of subsequent studies and radiological wonitoring s¢tivities are estimated to be approximately 814 per year for FY 1974 and beyond. DOD costs for cleanup and related sctivities are estimated at betwean §20-40% and may go higher. The actual final costs are highly dependent on amount of sofl end debris needed to be removed and subsequant disposal methods employed. To date the DOD has eousitted approximately 85O0K in che ore «leanup engineering survey. OFFICE » SURNAME bp __ DATED Form AEC-318 R-. % >t AE M “24 0 Aae nC
