ca cae nnn a alr emt ° As an example of the complex radiological situation which exists on Eniwetok, one island, Runit, is 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 has confirmed the presence of a plutonium-bearing, sand 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 eurface. Earth and debris moving activities during and after test operations have resulted in a complex radiological situation in which adjacent areas may be quite different as to levels and vertical distribution of radioactivity in soil. Data available to date indicate that radiological contamination is less severe on other islands but is sufficient to pose a considerable problen. At a September 7, 1972, Interagency Meeting, the following agreements with respect to funding were reached: we (a) The AEC will fund the radiolopical 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 developments of standards, 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 AEC in support of cleanup, AEC should be reimbursed by DOD. (b) DOD would be responsible for funding the engineering portions of the precleanup survey and those monitoring and survey activities that are required to support cleanup operations and to insure safety of personnel involved in cleanup activities. DOD also would fund the later cleanup of both radiological and non-radiological activities. DOI would be responsible for funding rehabilitation costs once cleanup is completed. DOE ARCHIVES Present best estimate of the cost of the AEC precleanup radiological survey is $1.3M. Coste of subsequent studies and radiological monitoring activities are estimated to be approximately $1M per year for FY 1974 and beyond. DOD costs for cleanup and related activities are estimated at between $20-40M and may go higher. The actual final costs are highly dependent on the amount of soil and debris needed to be removed and subsequent disposal methods employed. To date the DOD has committed approximately $500K in the precleanup engineering survey.
