Historically at the
, a radiation control technician (RCT) and industrial safety personnel first enter a facility in order to establish accurate conditions for planning purposes. When performing an initial radiation survey, the RCT uses a standard Geiger-Mueller pancake probe to gather radiological information. Once this initial entry has been completed, a video technician may also be required to enter and collect video coverage. Finally a team of sampling technicians is sent into the facility to collect samples used to determine contamination levels and identify which isotopes are present. Typically, this data is then used to aide decontamination and decommissioning (D&D) planning activities.
