Chapter 3 BIKINI OPERATIONS 3.1 Facilities and Services Operations similar to those at Eniwetok were carried out at Bikini. Control points were established as required, primary points being the boat landing and the helicopter pad, In addition, for afloat operations, check points and radiological-safety centers were established on the USNS Alnsworth, the USS Curtiss, the USS Badoeng Struit, the USS Estes, and the USS Catamount. These rad-safe centers included plotting and briefing areas, clothing and equipment issue points, and personnel-decontamination stations. Radex areas were established as required in a manner similar to that discussed for Eniwetok. 3.1.1—Personsel-decontamination facilities, which were a duplicate of those on Eniwetok, were established on Enyu Island adjacent to the Rad-Safe Building. Approximately 3400 people were processed, Laundry services necessary to maintain the protective clothing were provided by H&N personnel using the laundry facilities that were installed on the rad-safe barge. This barge provided complete personnel-decontamination facilities as well as laundry facilities and was to be used only in the event that operations were to be conducted entirely from shipboard. Only the laundry facilities were ever used. 3.1.2—The equipment-decontamination station on Bikin! processed approximately 100 vehicles during the operation. In addition, several helicopters were decontaminated for the Marines. Army Chemical Corps decontamination trucks were used for all equipment-decontamination operations as no steam generator was available at Bikini. 3.1.3—As at Entwetok, the Plotting and Briefing Section was responsible for all surveys. These surveys were coructed by helfcopter. A pre-entry survey was flown at H+2 to H+4 br, with a detailed one following at approximately H+6 hr. Other detailed surveys of the entire atoll were flown on - 29 =
