Based on the results of the radiological-safety surveys, R-hour was established at 0900on 2 November, and unrestricted radiological-safety clearance was declared for Parry and Eniwetok Islands and all lagoon water traffic south of Japtan Island. TU 7 set up their headquar- ters in Building 57 on Parry Island by 1200 hours on this date. Re-entry of the Task Force vessels into the lagoon was accomplished by approximately 0945 on 2 November, and the first personnel were ashore by approximately 1045. The re-entry of H&N personnel was accomplished in the following order: 1. Division heads, including the doctor. 2. Personnel to float and operate the M boats. 3. Personnel necessary to restore and operate the power, water, and telephone systems. 4. Complete mess hall complement. 5. Maintenance crews as necessary. The priority of re-entry of TG 132.1 personnel was based on the need for scientific and staff personnel to complete recovery operations and to begin the necessary preparations for King Shot. Certain TG 132.1 personnel remained afloat for a few days until adequate HEN support facilities were available. All personnel of TG 132.1 were ashore by M+4 days. All personnel who went ashore on the morning of M+1 day were provided with lunches for the noon meal. The H&N mess hall was open for the evening meal. On 3 November unrestricted re-entry was declared for the islands of Aniyaanii and Japtan, including lagoon traffic to these islands. Small boats were further authorized to travel in the northern half of the lagoon if they were accompanied by a monitor from TU 7. As radiological-safety conditions permitted, re-entry into other islands was permitted. Work on Runit was authorized on M+2 days. 3.12.2 t King Shot Since a complete personnel evacuation was not required for King Shot, the re-entry problem applied only to the islands north of Parry. Again, thé re-entry to these islands was based on radiological-aafety surveys which were accomplished in much the same manner as those following Mike Shot. 3.13 DOCUMENTARY PHOTOGRAPHY Operation Ivy was documented on film, both still and motion picture, ground and remote, as a basis for a photographic record for historical purposes and as a motion-picture report to the JCS and AEC depicting the scope and conduct of Operation Ivy. The JCS, at the request of JTF 132, established a military requirement for the USAF Lookout Mountain Laboratory to support Operation Ivy, and Headquarters USAF approved its employment to organize and sup- port a documentary photographic unit (TU 9) as part of TG 132.1. Complete documentary motion pictures and still coverage of Operation Ivy were required and obtained. A scientific historical documentary motion picture which summarizes the record of the operation will be produced. This film will not be limited by security classification. The film will not be required to contain material classified Top Secret Restricted Data; however, this material may be included if it is deemed necessary to portray the history of the operation. In the event the film is Top Secret, only three prints will be made. In the eventthe film being processed is given a final security classification of Top Secret, this print will be reedited to produce a film with a lower security classification so that it may be shown to larger audiences. To produce this version, various Top Secret sequences will be removed which will make the classification no higher than Secret. Seven copies of the reedited version will be made. 37
