Why is maintaining an inventory of sealed sources and portable gauges important?

• A. Increases administrative burden with no benefit.
• B. Optional.
• C. Maintaining an inventory of sealed sources and portable gauges ensures traceability and accountability.
• D. Only for decorative purposes.

Answer: (B)

Maintaining an inventory of sealed sources and portable gauges is essential for traceability and accountability throughout the item’s life cycle. For each source or gauge, you record its identity (such as serial number), activity, calibration status, current location, and the person responsible for it. This creates an auditable trail inspectors can review, helps verify that nothing is missing or misplaced, and ensures safe handling, transfer, and eventual disposal. If something becomes unaccounted for, you can promptly investigate to locate it or report it, reducing the risk of exposure or improper use and preventing orphan sources. Regulatory requirements and license conditions typically mandate accurate inventories, so this practice is a fundamental part of a responsible radiation protection program. It isn’t merely an administrative burden or optional, and it isn’t for decorative purposes—it's a necessary safety and compliance measure.
