Eneu Eneu, the second largest island, is located along the southeastern rim of the Atoll near the main channel opening into the lagoon (Figure 1). The island was the logistics center for the atoll during the testing period. aircraft runway is located on the southern part of the island. Several piers are on the lagoon side. Towers are located at both ends and near the island center. Buildings are numerous - a large assembly building near the south tower, the terminal building and hangar near a large concrete parking area adjacent to the runway, and personnel housing along the Village Road and along the northeastern ocean beach. Only a few parts of the island seemed to have escaped the construction activity, notably the central region in the northern half, where there were a number of coconut-bearing palms. In general, the island was less overgrown with wild brush than was Bikini. Radiation levels on Eneu were quite low - among the lowest measured on the atoll. This island was the farthest away from the main testing locations along the north and northeast reef and was also favorably located to avoid fallout, including that carried eastward from shot Bravo. Measurements were made primarily near the road which runs along the lagoon side of the island. This is the area of most probable past or future native settlement.
