  • a carriage adapted to be movably mounted on said length of pipe;

    a source emitting a beam of penetrating energy mounted on said carriage;

    a detector array having a plurality of detectors arranged in an elongated array to receive and measure the intensity of said beam of penetrating energy, said detector array mounted on said carriage in a spaced apart relationship with said source so as to allow the diameter of the pipe to pass between them as the carriage is moved axially along its length, said detector array oriented so that its length is positioned generally perpendicular to the intended path of travel of the carriage along the pipe.
