1. A system for detecting radioactive contamination of scrap in a vehicle, comprising:

  • a first detector positioned proximate a roadway for detecting the presence of a moving vehicle;

    at least first and second laterally spaced scintillators downstream of said first detector, said scintillators being disposed on opposite sides of the roadway for therebetween defining a scan zone;

    a second detector positioned proximate the roadway downstream of said scintillators for detecting the presence of the moving vehicle;

    a vehicle identifier proximate one of said scintillators for identifying the vehicle detected by said detector;

    a controller operably associated with at least said first detector, said scintillators, and said identifier for activating said scintillators upon said first detector detecting a vehicle, for determining whether the vehicle contains radioactive contamination upon completion of a scan made by the scintillators, and for activating an indicator system should radioactive contamination be detected; and

    a visual indicator operably associated with said controller for identifying the vehicle having the contamination and an audible indicator operably associated with said controller for indicating the detection of contamination.
