| Abstract | Analysing archaeological artefacts made from metallic alloys is often challenging due to the impracticality of sample collection. Traditional non-invasive surface techniques, such as X-ray fluorescence (XRF), electron probe microanalysis (EPMA), scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX), and particle-induced X-ray emission (PIXE), among others, may yield misleading results if the objects are affected by corrosion or enrichment effects. Consequently, these techniques need to be complemented with others to gain a precise understanding of alloy composition. Gamma-ray transmission (GRT) is a non-destructive technique that can reveal the bulk composition of a sample. A new GRT setup has been developed to measure the concentrations of binary, ternary, and quaternary alloys using three sources simultaneously, reducing the measurement time. Alloys made in the laboratory were analysed with XRF, showing notable composition discrepancies in some cases, while the GRT results agreed with the expected composition. This innovative GRT setup, with its potential to contribute to future archaeological investigations of alloy compositions, proves to be a valuable tool for analysing metallic artefacts. © 2025 Elsevier Ltd |
