A. We have compisted an estinate of radiation fosages to be
received by Task Group 7.4% personnel during Operation RARDTACK.
Results iniicate that only aircrevs of sampling aircraft and possibly
af Program 5 effects aircreft can be expected to be axposed to raeiiation dosages greater than the normal operstional limit established
by JTF SEVEN for JTF SEVEN personnel during REDWIN). This linit was
published in Annex K, JTF SEVEN Operational Plan 1-56, and was ee
tablished at 3.9 roentgens (3.9r) for any 1}-veek period.
R. We understand that requests for special maxim peruissibie
exposures (NPR's) for Program 5 aircrews, if required, will be re-

3. uring REDWING a Limiting dosage of twenty roentgens (20r)
wes established for saxpler cress.
In actual fact, however, sampler
crews achieved an svereage exposure of 5.9 roentgens (5.9r) per man and
the maximm individual exposure was 9.8 roentgens (9.8r) while senpling.
In addition, es did everyone elee om Enivetck Island, these individuals
received sbout two roentgens (@2r) per man fron secidental fallout
@uring the operation.
hk. We believe that the averege sampler crew meniber guring RARDTAX
will bave to be exposed to greater total radiation exposure than this
uverage crewnsn during REDWING.
‘There are tvo (2) reasons for this:

Shere are move shots to be sampled.

There are nore shots at Bikini, where the dosage is
greater than at Enivetok because af the greater fiy-hame distance.

BARDIACK will go to approximately eight roentgens (8r) and the maximum |
for any individual may go as high as tvelve roentgens (ler) exclusive
of possible accidental fallout on Bnivetok.
