unintentional radiator
An unintentional radiator or incidental radiator is any device which creates radio frequency energy within itself, which is then unintentionally radiated from the device.〔(47 CFR 15.3 - Definitions )〕 This can interfere with other electronic devices.
==Example radiating devices==
A computer is a typical example, where spurious emissions may not be contained within the case.
A radio receiver will often use an intermediate frequency which is detectable outside the radio—the concept behind at least one audience measurement concept for roadside detection of radio stations which passing motorists are listening to.
Other examples include the motor, transformer, dimmer, and corona from electrical powerlines. Unintentional radiation from these devices can create interference on AM radio, and on the video of television stations.
