Abstract: This system relates to a system ( and a corresponding method ) of automatically sorting objects, wherein said system comprises a conveyor mechanism configured for conveying an object to a sorter device; a sensor device arranged such that the objects conveyed are caused to be located essentially within a predetermined reading space; and a calculator unit configured for receiving an electrical sensor signal representative of measurement data from said sensor device and configured for generating and emitting a control signal to said sorter device configured for sorting conveyed objects in response to/on the basis of said control signal, wherein said sensor signal is configured for detecting gamma radiation emitted from a conveyed object when exposed to a neutron flux with a given energy distribution, and configured for providing said sensor signal on the basis of said detection; and wherein said control signal is generated on the basis of said sensor signal.
