ant PROCEDURE The flight altitude end operational plans were coordinated with the AOC (TG 7.4) and this organization assumed primary guard and SAR responsibility for the mission, The atoll and lagoon (Phase A and B) were surveyed immediately after take-off (1130 to 1230) and concluded with altitude correlation passes over Engebi at 100, 200, 300 and 500 feet. The area out to sea was surveyed from 1239 to 1500, and the mission terminated at Eniwetok. Based on the survey results, the aircraft was released for return to PATRON ONE at Kwajalein and the D+2 survey cancelled. The project equipment was installed, checked, and calibrated in the helicopter from 1015 through 1230 on D+#2. proceeded to Aomon. The mission then left Parry and Altitude runs were made across the bunker. The helicopter was hovered for one minute at 500 and 800 feet altitudes to obtain gamma spectral data. The pilot could not hover at less than 500 feet, so that lower altitude data was not obtained. Rojoa was selected to provide intensity data over an area with a lower density of contamination. 50 to 500 feet. fititude passes were run over the air strip from The open water runs were cencelled due to the extremely low levels of water contaminetion available. TEST FESULTS The eerial survey over the islands of the Eniwetok Atoll have been correlated to surface intensities. Examination of this data shows little or no fallout except the northeastern islands. Parry and Eniwetok were not surveyed, however, fallout intensity measured at the surfece reeched a peak of 20 mrfhr on Dl, No contamination could be detected in the lagoon or at sea, sround the atoll.
