A limited number of recoveries were made using trucks and heavy equipment, such as tractors. Recovery by this means was limited to the complexes on which safe parking was possible during the shot. This system was successfully used on the Rojoa complex for recovery of the detector cable lincs; however, prompt recovery on the Teiteiripucch! complex by this method was unsuccessful due to contamination of the tractor and land areas, This recovery was delayed for several days and, eventually, was accomplished using substitute cquipment, Precautionary measurcs were observed on those missions entcring hot areas where engine failure or other mishaps could result in dangerous radi~ nifan overdose, Recovery terins and helicopter or boat crews were thor- ouchly briefud on the nroecdures to be followed and the signals to Fo used, and stand-by helicopters and houts were provided. At Eniwetok Atoll, the main camp on Parry was not evacuated for any of the events, Wo-tsland camps were evacuated as required by specific exerts, Re-entry consisted of postshot recovery missions as governed by the 1adiolugical conditions; und as levels went down, by the re-entry of work parties preparing fur subsequent shots, and in the case of Runit, by_re- establishment of the camp on a lmited basis five days after’ “res fired, 2.11.3 Bikini Recovery and Re-entry The scope of the data recovery probiem at Rikini depended on the number of experimental projects participating on a given shot. Once the early recoveries were completed, Inter recoveries phased inte and became a part of the general re-entry, which involved, among other things, the carly transfer of control of operations from ship to shore without interruption and without disruptica of transportation services, and re-establishment of camp services as soen as possible. The procedure used to accomplish this recovery~re-entry was, in general, as follows. When the Radoeng Strait had clused to within about five miles of FEnyu Island (usually at approximately H+ 1-1/2 hours), two radiological survey helicopters were launched (via USS Curtiss for Rad-Safe Officers and the CP on Enyu, 28 appropriate, for CTG 7.1) to obtain information concerning radiological situation at FEnyu and in the lIagvon, and, as conditions permitted, gencral lines and levels of contamination throughout the atoll, As soon as definite indication was received that Enyu and the anchorage were clear, permis<ion was obtained to proceed with early recovery missions and with the initial phase of re-entry.
