Final report must include what XRF data?

Final report must include what XRF data?

• A. All raw data and laboratory results
• B. Only final results
• C. Calibration certificates
• D. Photographs of the test area

Answer: (A)

Documenting XRF results with complete data sets ensures traceability and integrity of the final report. The best approach is to include all raw XRF data—such as spectra, counts, instrument settings, and sample IDs—along with the laboratory results derived from that data, and any QA/QC notes and calibration information. This level of detail lets someone verify how the final numbers were obtained, reproduce the analysis, and confirm that data processing didn’t alter conclusions. Simply presenting final results hides the steps and evidence behind them, which can be critical for audits and regulatory review. Calibration certificates matter as supporting documentation, but they don’t replace the need for the full raw data and per-sample results. Photographs of the test area aren’t part of the data package used to substantiate the XRF results unless there’s a specific, stated requirement for site documentation.
