+ aan eatitnnah emer Meaty enabled helicopter and LCM recovery missions to begin as soon as possible. Crews began decontaminating the small craft left behind in the lagoon during the shot. Likewise, personnel on board the Bairoke decontaminated HMR-362 helicopters as they returned aboard the carrier from survey or recovery missions. A returning helicopter would land in the canvas bathtub, where it was scrubbed and hosed down with fresh water Pp. (Reference ll, 6-7). After initial survey and recovery efforts were underway, the Curtiss and the Ainsworth returned to the lagoon, followed by the rest of the task group ships. These vessels entered last since many of their postshot ac- tivities were dependent upon radiological surveys of the water in the vi- cinity of the shot site (Reference ll, p. 6-7). Table 10 summarizes radsafe-related activities at Bikini near each shot time. ENEWETAK SHOT. Shot NECTAR, fired on 14 May at 0620, did not require a full-scale evacuation of Enewetak Atoll. Instead, personnel moved to Enewetak, Parry, and other islands in the southern portion of the atoll. Nevertheless, "all ships were evacuated to nearby operating areas at sea aS a precautionary measure." Reentry began immediately after the detona- tion and within an hour all ships had returned to their berths in the lagoon in readiness to evacuate the atoll should fallout pose a danger to personnel (Reference 11, p. 6-8). POSTEVENT SAFETY MEASURES General Procedures All personnel on Bikini were evacuated before each detonation. Early reconnaissance by helicopter established the radiological levels in the lagoon and on the islands of the atoll. All islands were considered con- taminated until cleared by TG 7.1 Radsafe Control personnel. Preoperation planning called for Enewetak postshot control and decontamination activities to be centered at Enewetak and Parry islands. On ws 125
