Claim 8:
9. A method for analysing and/or sorting scrap aluminium, comprising:
providing a conveyor system for conveying scrap bundles;
a measuring device, which has at least one neutron source for irradiating scrap bundles conveyed on the conveyor system, and at least one detector for capturing gamma radiation emitted by the scrap bundles as a result of this neutron irradiation; and
a computation device which is arranged to determine composition information relating to the composition of one or more scrap bundles conveyed on the conveyor system on the basis of the gamma radiation captured by the at least one detector,
in which a plurality of scrap bundles and/or a plurality of groups of scrap bundles are provided, a scrap bundle being understood to mean a quantity of scrap fragments which are pressed together to form a bundle,
in which the respective composition information for the scrap bundles and/or the groups of scrap bundles is determined in that the respective scrap bundle or the respective group of scrap bundles is irradiated by at least one neutron source, the gamma radiation emitted by the respective scrap bundle or the respective group of scrap bundles is captured by the at least one detector, and composition information relating to the composition of the respective scrap bundle or the group of scrap bundles is determined on the basis of the gamma radiation captured by the at least one detector.
