In this interview, Mary Kate Donais discusses the portable analytical devices used to uncover the secrets of the past. Can you tell us about how you came to work in archaeometry? I arrived at this ...
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
XRF stands for X-ray fluorescence, and the technique works by shooting high-energy X-rays at a sample and reading the unique “glow” of secondary X-rays that bounce back. It can detect elements ranging from chlorine to uranium, and results come back in seconds to minutes depending on the setup.

XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source.
Learn about XRF standards, calibration methods, and sample preparation techniques to ensure accurate, reliable, and comparable X-ray fluorescence analysis results.
An XRF analyzer is a sophisticated scientific instrument used for non-destructive elemental analysis. It allows users to determine the precise chemical composition of a sample—such as a gold ring, a silver bar, or a complex alloy—in a matter of seconds.

XRF describes the process where some high-energy radiation excites atoms by shooting out electrons from the innermost orbitals. When the atom relaxes, that is, when outer electrons fill inner shells, X-Ray fluorescence radiation is emitted. All this happens without touching or damaging the sample.
