- 10 best completed after return of the expedition to laboratories on the mainland. (4) Biological material collected in the field should be packaged, frozen, and dispatched to the Applied Fisheries Laboratory in a frozen state by Military Air Transport Service or other authorized carrier, accompanied by a member of the field party. Operation Schedule It is estimated that 30 to 40 days in the field should suffice to make the preliminary survey and to gather the samples needed to evaluate the immediate after-effects of radiation contamination. Time consumed in travel is difficult to predict but with sufficiently high priority it should be possible to complete the trip each way in 4-5 days. If time permits, a collecting trip to Likiep Atoll should be undertaken to obtain additional “control" material from an uncontaminated area.
