Claim 0:
1. 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 quantity of scrap metal in the form of a scrap bundle or a group of scrap bundles is provided, a scrap bundle being understood to mean a quantity of scrap fragments which are pressed together to form a bundle,
in which the scrap bundle or the group of scrap bundles is irradiated by the at least one neutron source,
in which the gamma radiation emitted by the scrap bundle or by the group of scrap bundles is captured by the at least one detector, and
in which composition information relating to the composition of the scrap bundle or the group of scrap bundles is determined on the basis of the gamma radiation captured by the at least one detector.
