Radio frequency (RF) fields are a widespread occurrence produced by high-power broadcast systems, such as AM/FM radio, television, and other communications systems. Other RF sources include power lines, transformers, electromechanical switches, computers, cellular phones, medical equipment, and natural sources like lightning. The potential hazards of RF fields include the disruption of radio and TV signals, poor connectivity between communication points and systems, electronic eavesdropping, malfunctioning medical equipment, and in some cases, the detonation of explosives. RF doors are an integral component of a room designed to contain radio frequencies. The conductive surfaces on the ceiling, floor, walls, and door assembly all interface together to form an impermeable RF shielded enclosure. RF shielding is designed to reduce electromagnetic emissions to prevent the transmission of sensitive information outside of the shielded facility as well to exclude external RF noise from penetrating the shielded enclosure and adversely affecting sensitive equipment or test environments. RF shielding doors are installed in a variety of facilities such as embassies, X-ray imaging and medical facilities, military installations, government buildings, communication centers, sensitive compartmented information facilities (SCIF), radio stations, computer rooms, and transient electromagnetic pulse emanation surveillance technology (TEMPEST) sites.
