XRF stands for which technique?

• A. X-ray Flux Radiation
• B. X-ray Fluorescence
• C. X-ray Frequency Radiation
• D. X-ray Formulation

Answer: (B)

X-ray Fluorescence is the technique described. In XRF, a sample is irradiated with X-rays, which excites the atoms inside. The excited atoms emit secondary X-rays at energies characteristic of each element. By measuring these energies and their intensities, the instrument identifies which elements are present and how much of each there is, such as lead. This makes XRF a fast, non-destructive method suitable for on-site screening of paints, metals, and soils. The other phrases aren’t recognized techniques for this purpose.
