stationed at EPG during Operation HARDTACK will be established as 3r.
to go aboard the target ships as soon as possible after WAHOO in order to
effect repairs, recalibrate equipment and make preparations for UMBRELIA.
3. In anticipation of the relatively early re-entry needed by Project 3.4
after WAHOO and the extended work requ ted aboard the target ships between
WAHOO and UMBRELLA, it is most desirable that the radiation dosage limit
for Project 3.4 personnel be raised to 4r.

participated in an atomic test before and that the earliest possible
participation after WAHOO and UMBRELLA tests will be in 1960.
It should
further be noted that every effort will be made to keep personnel exposure
as low as possible.
5. The Burem of Medicine and Surgery was approached by reference (a) with
respect to this change in the radiation dosage limit and has no objection
to this increase (reference (b)).
6. It is therefore requested that the radiation dosage limit for Project
3.4 personnel be raised to ér.
