Early in the field execution phase of these prograns, it was decided to abandon a rigid grid survey pian for the terrestrial radiation evaluation. Utilizing the aerial survey information, portable instrment readings were taken on the ground at each soil collection location. Thus, the aerial and ground readings could be correlated directly with the soils data. These would then be evaluated with the TLD information to produce an integrated statement of the terrestrial radiation exposure rates for all areas of the Atoll. The physical effort utilized to collect both soil samples and obtain instrument radings would then be minimized. The execution of a program to collect several thousand soil samples end obtain a similar number of instrument readings from an atoll with 43 separate islands was no mean feat. A brief discussion of what was involved in the field effort is appropriate to engender an appreciation of the problems encountered in conducting such a program and their effect on program desifn, scope and execution.
