Data underlying the publication: Exploiting activation radiation from neutron tomography reveals the hidden elemental composition of 3D art objects for free

This dataset was collected in an experimental study aimed at investigating the internal structure and elemental composition of the Kuvera statuette (object number: AK-MAK-311, c. 850–930, the Rijksmuseum Amsterdam) using a Geant4-based data fusion method that combines neutron tomography (NT) and gamma spectroscopy (GS). NT provided the statuette’s internal features, while gamma spectroscopy measured its elemental information. The dataset contains NT projections and GS spectra.
