A generally licensed device, or “GL” device, is a device containing radioactive materials that is typically used to detect, measure, gauge, or control the thickness, density, level, or chemical composition of various items.
Examples of GL devices include:
- Tritium exit signs.
- Gas chromatographs.
- Density gauges.
- Fill-level gauges.
- Static elimination devices.
A general licensee is a person or organization that acquires, uses, or possesses a GL device and has received the device through an authorized transfer by the device manufacturer or a distributor.
We register and track these GL devices in order ensure they are properly maintained and disposed of or transferred properly.
