The aerial survey revealed hot spots on several islands which then received special attention from the terrestrial effort. Concern over the contradictory nature and adequacy of the earlier rad-safe support reports was justified when the aerial survey also located an abandoned 69c9 source at the site of an old dosimeter calibration facility on Parry Island (ELMER). This source was recovered and taken to the Nevada Test Site for burial in an approved disposal site. . A complete set of aerial photographs of all the land and reef areas of the Atoll was obtained as a byproduct of the aerial survey. photographs were invaluable: These assisting in locating the safest approach to islands for landing efforts, locating survey party positions and objects more exactly in the field, and determining the most efficient route to locations. Statistical Planning Basic Objectives The general objective of the Eniwetok Precleanup Survey was stated “to be: “to thoroughly evaluate radiological conditions on all islands of the Atoll prior to commencement of cleanup activities in order to provide sufficient radiological intelligence to be able to develop an appropriate cleanup program to be accomplished ,"~/ This overall objective was interpreted to provide specific goals for the soil and terrestrial radiation survey program, These extended objec- tives were: 1. To conduct a sample collection and terrestrial radiation survey program which would assure truly representative sampling of the soils and determination of the radiation 1 EO eee 1 em orem er ments aio . em me ga
