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. | ae SURNAMEp | a cf ee OFFICE p | 1 t ATE “apm AEC-318 (Rev 9-53 ARCM J co co : Le ) 024 1 . “4s cree fieeee ~~ oo “AO .
