What does XRF stand for?

• A. X-ray fluorescence spectroscopy
• B. X-ray fluorescence
• C. X-ray radiative factor
• D. X-ray filtration

Answer: (B)

XRF is the shorthand for X-ray fluorescence. When a material is irradiated with high-energy X-rays, its atoms emit secondary X-rays with energies that are characteristic of the elements present. Detecting and analyzing these emitted X-rays lets you identify and quantify the elements in a sample. The phrase “X-ray fluorescence spectroscopy” describes the analytical technique that uses this phenomenon, but the common expansion of the acronym XRF is simply X-ray fluorescence. The other options describe unrelated terms, so they don’t fit the standard meaning of the acronym.
