What is the difference between federal and state licensing for radiation sources, and what records are typically required?

• A. NRC federal license vs state license; records include inventories, dosimetry, calibrations, training, waste logs and incident reports
• B. Federal license only; no records required
• C. State license only; minimal records
• D. No licensing required

Answer: (A)

Licensing for radiation sources involves who has regulatory authority and what must be documented to show ongoing safety. In the United States, the Nuclear Regulatory Commission issues federal licenses for possession and use of many radioactive sources. States that have an agreement with NRC take on the primary licensing role within their borders, enforcing the same or compatible requirements. So, you can be dealing with a federal license or a state license depending on where you operate, but the important point is that some form of licensed authority exists to regulate these sources and ensure safe practices.

The records you’re expected to maintain are aimed at proving control over the sources and monitoring worker exposure. An inventory shows every source you have, with details like type, serial number, and location. Dosimetry records document occupational exposure for workers, reflecting the doses received over time. Calibrations of instruments and survey meters ensure readings are accurate and measurements are reliable. Training records demonstrate that staff have completed the required radiation safety training. Waste logs track radioactive waste from generation through disposal, ensuring proper handling and compliance. Incident reports capture any spills, losses, or unusual events so they can be investigated and corrected. Together, these records support accountability, safety, and regulatory audits.
