What is a generally licensed device (GLD)?
Under Title 10, Section 31.5, of the Code of Federal Regulations (10 CFR 31.5), “Certain detecting, measuring, gauging, or controlling devices and certain devices for producing light or an ionized atmosphere,” a “generally licensed device” is defined as a device containing radioactive material in a sealed source (that is, a shielded, sealed housing). Such devices must be designed and manufactured with inherent radiation safety features so that they may be safely used by someone with no special radiation training or experience. Examples include static eliminators, ice detection devices, gas chromatographs used in chemical analysis, and certain in vitro kits used in clinical or laboratory testing. Owners of such devices must fulfill certain recordkeeping requirements, but because of the built-in safety features, they do not have to apply to the NRC or a State regulatory agency for a specific license to possess or use the radioactive material.
