4.12.3

Dose Summary for Operation WIGWAM.

The maximum dose limit for WIGWAM was 3.9 rem of gamma radiation for the
duration of the operation.

The two vessels (YAG-39 and YAG-40) stationed

downwind of the detonation were subjected to contamination by water droplets
of the base surge.

Because of the special shielding, however, none of the YAG

personnel exceeded the radiation limit.

All doses were low because most of

the radioactivity was confined deep under the surface of the water (16: 10,11).
WIGWAM was the first series in which nearly all participants were issued
film badges.

Personnel whose duties were such that exposure to radiation was

possible (such as sampling radioactive water, recovering equipment or
instruments) were issued additional film badges on a daily basis.

One of the

vessels, the USS Wright, contained a film processing center where badges were
read and personnel exposures were recorded.

Over the period of the operation,

approximately 10,000 film badges were issued (16: 10).

4.13 OPERATION REDWING.
REDWING was conducted in 1956 as the sixth nuclear test series at the
Marshall Islands, specifically at Enewetak and Bikini Atolls.

The series

consisted of the 17 detonations identified in the accompanying table.
