STATUS REPORT ENIWETOK RADIOLOGICAL SURVEY (As of December 1, 1972) (See Attached Map) This report summarizes significant activities and results to date of the radiological survey in progress on Eniwetok Atoll. The aerial survey of all islands was completed on November 23, 1972, and included radiation missions (high and low energy scales) and black and white and multispectral photo coverage. All high energy radiation missions were flown on 150-foot grid paths (parallel to longitudinal axis of islands). Time and weather constraints dictated that majority of low energy missions be flown on 300-foot grid spacing. Exceptions were SALLY, JANET, ALICE, BELLE, YVONNE, and TRENE. Photo processing and data handling initially were impeded by power outages on Eniwetok, which causedwater shortages and loss of air conditioning for computer operation. Even so, some data reduction was accomplished and overlay radiation contour plots have been completed for 16 islands. provided in the attachment. Observations regarding these plots are A map of the Atoll is also attached to aid in identification of island locations. A partial ground survey was accomplished on OLIVE and BELLE and it is interesting to note that correlation of aerial and ground measurements thus far is excellent; a fine demonstration of the sensitivity of the aerial equipment. Ail data from the aerial survey has now been returned to CONUS for completion of processing.
