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.
