USS Sioux and other vessels from TG 7.3
Operations:
Water-sampling and submerged radiation-meter t@chniques
were used to obtain fallout data in free ocean areas.
Folldwing
YANKEE and NECTAR, vessels traversed fallout fields, collecfliing data
used in conjunction with aircraft surveys conducted by the
.
(Times involved were H+6 to D+4 for YANKEE, with completionfof operations for NECTAR by 0530 on D+2.)
Shots:
YANKEE (Bikini); NECTAR (Enewetak).
Radiation Exposure Potential:
High for all personnel colledting sam-
ples, less severe for those performing the aerial survey or]ffor those
shipping samples to NRDL for analysis.
Staffing:
Seven civilians were associated with this proest four
from SIO and three from NRDL.
Exposures for crews of the n
al ves-
sels appear in Table 59.

Operations:
Two samples (on 7 and 9 May) were taken from tlle
while traversing the fallout pattern subsequent to YANKEE.
