Who should monitor the XRF for leakage?

• A. Owner
• B. RSO
• C. QA Supervisor
• D. Technician

Answer: (B)

XRF devices used for lead inspections often contain sealed radioactive sources, so there are regulatory and safety requirements to check for any leakage or contamination. The Radiation Safety Officer is the person designated to oversee all aspects of radiation safety, including monitoring sealed sources, performing or supervising wipe tests, keeping leakage and survey records, and taking corrective action if leakage is detected. This role is specifically responsible for ensuring the device remains within safe operating limits and complies with regulations. While the owner handles overall compliance and the technician operates the instrument, and the QA supervisor focuses on QA procedures, the duty of monitoring leakage rests with the radiation safety professional.
