The purposeof this Standard Operating Procedure is to establish procedures fur the following types of ground surveys at Eniwetok Atoll: (a) Initial Recovery Survey. This is a survey made at each recovery station prior to commencement of recovery operations at the station. (b) Recovery Survey, This is the survey made by the monitor accompanying the recovery party. (c) Reentry Survey. This is a survey made of an island to clear it for reentry. C.13.2 Initial Recovery Survey (a) General, When the radiological intelligence indicates that recovery operations may be initiated at a station or stations, the Control Officer will send a monitor to make a ground survey there. From these data the Control Officer will be able to advise the recovery party of the radivlogical hazard. (6) Personnel and Equipment. The initial recovery survey will be made by a monitor using a helicopter for transportation. Intensity readings will be taken with a T1B survey meter. The monitor will be provided with a map or aerial photograph and with a special overlay grid of the island or islands concerned. A duplicate set will be retained at RIC for inter. He will not undertake to make a more extensive survey than that required for accomplishment of the recovery. C.13.3 Recovery Survey Each recovery party wiil be accompanied by a monitor with a TIB survey meter. The same general instructions for the init.al-recovery monitor apply. The recovery monitor must be prepared to advise the recovery party of any new or previously undetermined radiological hazards encountered. He will report ra-liological information to RIC as prescribed, C.13.4 Reentry Surveys fa) Elmer. The ground survey monitor and an assistant will leave the USS Rendova, when directed, for the air strip on Elmer. They will carry two TIB survey meters and appropriate aerial photographs and grid overlays. A '%-ton 4 by 4 truck will be parked at the RadSafe Building (Buiiding 57) for their use. The ground-survey monitor will proceed to survey 13 LAND DAMEN <Cre meerememren aeemmenaraernes ‘ (c) Procedure, The initial recovery monitor will determine the most practical route of entry to the station. He will direct the helicopter pilot to land as close io the station as possible. Upon landing the monitor will dismount from the helicopter and approach the station. If ihe station is reached, he will report the intensity at the station to RIC. If a station cannot be approached, this fact will be reported together with the intensity at the point of nearest approach. The monitor will complete the survey expeditiously and leave the contaminated region. TAALOADAG SARHS NanaeAF OP mt etaCait Ont RmTRENERITA ke Ve wihon ee pretation of the coded data reports.
