XRF analyzers emit which type of radiation?

• A. X-rays
• B. Gamma Rays
• C. Neutrons
• D. Beta Particles

Answer: (B)

XRF analyzers rely on photons in the X-ray range to probe the sample. The instrument’s X-ray source emits X-rays that excite the atoms in the material, knocking out inner-shell electrons. When those vacancies are filled, the atoms emit characteristic X-ray photons. By detecting and analyzing these emitted X-rays, the instrument identifies which elements are present and in what amounts. Gamma rays come from nuclear processes, neutrons are used in other techniques, and beta particles are electrons from decay, none of which are the basis for standard XRF analysis. So, the radiation involved with XRF is X-rays.
