and experimental decontamination procedures were followed.

Approxi-

mately 300 men from various ships of TG 7.3 assisted in survey, sample
recovery, and ship and aircraft decontamination work.

Coordination of

this effort was done on the Estes.
Figures 48, 49, and 50 show the sequence of decontamination for
YAG-40.

Figure 48 shows the tug, Molala, hosing the ship down as she

returned to Enewetak.

Figures 49 and 50 show crews dressed in protec~

tive clothing on the YAG-40 using hoses from the YAG-39 to continue
the sequence.

Figures 51 and 52 show one of the aircraft carried on

the YAG decks being decontaminated at Parry (these were aircraft from
Alameda NAS that had been scheduled for salvage;

four were used in the

tests).

Shots:

BRAVO, ROMEO, UNION, YANKEE (Bikini).

Radiation Exposure Potential:

High for personnel aboard the vessels,

as well as for those engaged in recovery and decontamination operations.

For example, the average exposures received by NRDL and YAG

personnel were 0.170 R for BRAVO, 1.030 R for ROMEO, 1.100 R for
UNION, and 0.026 R for YANKEE.
Staffing:

One hundred and five people are specifically associated

with this project, including seven civilians for whom exposure records
are apparently unavailable.
