OPERATION HAQDTACK
Radiological Safety Support fer
all Target Fleet Projects.
The 3 week rad-safe training program for Project 2,10b demonstrated that
a 4 week course was required to adequately train BuShips and Navy erlisted
personnel into an efficient rad-safe groupe Cpsrationally, the logistic
support from TU-7 provided a minor obstacle in the supply ef protective
clothing. The rediac instrimentation support from TU-7 and TG 7.3 afforded
adequate coverage. Pnotodosimetry processing for the NRDL experimental
film badge program was carried out with the help of the Air Force. One-half
of the red-safe coverage of Project 2.105 was for the cperation and turn-
around of the YAGS 39 and 40 as wes els» the case in Operation CASTLE, The
baiance of the red-safe coverage for NRDL projects was accomplished adequa-
tely with support from T™-7 and TG 7.36
Some of the radiological monitoring data from ships and barges posit7.oned
in the fellout pattern from previous operstions are tabulated telow to
indicate the order of magnitude of the rediolcgicsl situztion:

Res’dual gamma radiation intensities of abeut 1000 rf/hr at H +i msy
be expected on the target fleet array on Operation HARDTACK. It. is to be
noted
that Romeo was a water surface shot <n the M? range, Wigwam w23 a
desp underwater shot ef about 30 KT and Tewa was a water surface shot, in
the HT range. The whole bedy gamma dosage was contrclied by rotating
personnel in the decontanination teams.
