Abstract
The invention discloses a scanning method and apparatus suitable for scanning a pipeline or a process vessel in which a beam of gamma radiation from a source is emitted through the pipeline or the process vessel to be detected by an array of detectors, which are each collimated to detect gamma radiation over a narrow angle relative to a width of the emitted beam of gamma radiation.
