Abstract
This invention provides a scanning system for scanning an object in a scanning zone. The scanning system includes both a radiation source arranged to irradiate the object with radiation having a peak energy of at least 900 keV and a scatter detector arranged to detect radiation scattered from the object wherein the radiation source is arranged to irradiate the object over a plurality of regions to be scanned within a single irradiation event. The scatter detector includes a plurality of detection elements, each detection element being arranged to detect scattered radiation from a predefined part of the scanning zone and a signal processor arranged to calculate scatter intensity across the plurality of detector elements.
