. - 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.
