X-ray fluorescence spectroscopy

Definition

X-ray fluorescence spectroscopy is a non-destructive analytical technique used to determine the elemental composition of materials by measuring the characteristic X-rays emitted from a sample when it is exposed to X-ray radiation. This method is especially valuable in archaeology as it helps in the analysis of ceramics and other artifacts, allowing researchers to identify the raw materials used and understand cultural and technological practices of ancient societies.
