What type of radiation does the XRF emit?

Explanation:
XRF devices emit X-ray photons. They generate X-rays to excite the atoms in a sample, and the atoms then emit characteristic X-ray photons as they return to lower energy states. This is how the device analyzes the sample and identifies elements like lead. Alpha and beta are charged particles from radioactive decay, and gamma rays come from nuclear transitions—neither is the type of radiation produced by the XRF itself. So the correct concept is that the radiation involved is X-ray photons.
