POST-OPERATION ORGANIZATION AND ACTIVITIES

After 7 September all survey and construction activities at Bikini were rapidly brought to a close, and the atoll was evacuated by 26 September 1946. Following a meeting on the West Coast from 17 to 20 September concerning decontamination procedures, some officers from JTF 1 were ordered to temporary duty under Commander Western Sea Frontier to follow up and coordinate the decontamination, monitoring, and clearance of exposed ships. On 24 September, in a joint speedletter, the Bureau of Ships and the Bureau of Medicine and Surgery assumed responsibility for giving final radiological ship clearances and prescribed detailed decontamination and clearance procedures. JTF 1 was formally dissolved on 1 November; its successor was a JCS committee, the Joint CROSSROADS Committee, whose task it was to oversee the final test activities, publish the final reports, and supervise the Bikini Resurvey Operation of summer 1947, described in Chapter 6 (Reference C.9.206, pp. V-(D)-5 through V-(D)-7).
