accomplish the unit mission independently. TU 7 personnel moved between the two centers as the radiological situation warranted. Subcenters of the Bikini Radsafe Center were established aboard a barge adjacent to the USNS Fred C. aboard the USS Estes. Ainsworth, aboard the USS Curtiss, and These substations were primarily control and per- sonnel decontamination points for TG 7.1 and TG 7.5. Since the concept of subcenters had not been considered in initial staffing procurement plans, full staffing was not available. TU 7 per- sonnel were thinly scattered throughout, reducing their effectiveness in some areas, but this did permit decentralized and controlled recovery operations. Dual communications between the Bairoko Radsafe Center and the subcenters were maintained by the task group administrative net and a dedicated frequency radsafe net. These nets permitted direct communication between control points and the dosimetry record unit aboard the Bairoko. Decontamination. The Decontamination Group of TU 7 was to provide for the protection of personnel against radiological contamination and to establish effective contamination control. The following arrangements were made for this: @ Personnel decontamination stations were set up at the Parry Radsafe Center, aboard the Bairoko and the Curtiss, and aboard a barge alongside the Ainsworth @ Equipment decontamination areas were demarcated at Parry @ Entry and exit checkpoints were established at Parry, aboard the Bairoko and the Curtiss, and aboard a barge alongside the Ainsworth. e Laboratory Analysis. The Laboratory Group provided technical assist- ance to the Radiation Control and Decontamination Groups and laboratory services to all JTF 7 radsafe organizations. The group maintained all radsafe instrumentation for JTF 7 and processed and interpreted all film 82 ;
