After obtaining cost estimates for logistics support from the DOD and the technical program from,ERDA, the Office of Management and Budget (OMB) determined that reimbursement of DOD's supplement. the survey would be conducted, and funds for logistics support were included in a DOI FY 78 DOE was directed to absorb the technical program costs. Although the U.N. Trust Territory Agreement with the U.S. is expected to end soon, it is clear that the U.S. will continue to have a vital national interest in the northern Marshalls. Resettlement of Bikini Island has suffered a setback due to radiation exposures significantly exceeding acceptable standards, and the conditional nature under which Enewetak is being resettled, and the need to continue following the health of the Rongelapese, will require radiological monitoring of these people and their environment for the foreseeable future. The aerial survey will be a major part of a standardized data base which will provide information needed for evaluating any future claims for damage or injury. It will contribute to :ne future monitoring program planned for Bikini, Enewetak, and Rongelap atolls. In addition to Enewetak, Bikini, and Rongelap Atolls, there are eleven other atolls or single islands that received intermediate range fallout from one or more of the megaten range tests. A number of these atolls are presently inhabited while others are used for food collection. operations, During nuclear test there was a limited monitoring program that did not provide anywhere near the coverage that can be obtained with the current aerial survey technology and instrumentation. In addition, there is little or no data on possible plutunium contamination outside of Bikini and Enewetak Atolls. The proposed aerial survey uses the same equipment and procedures which were successfully employed at Enewetak Atoll in 1972-1973. The people of
