Model		10 kHz to 30 GHz field strength measurements associated with a variety of environments and work sites
Details		Measurements of RF field levels (10 kHz to 30 GHz) associated with a variety of environments and work sites. Specific sources include Coast Guard navigational transmitters, a Navy VLF transmitter, computer visual display terminals (VDTs), induction stoves and range tops, industrial induction and dielectric heaters, radio and television broadcast transmitters, amateur and citizens band (CB) transmitters, medical diathermy and electrosurgical units, mobile and handheld transmitters, cordless and cellular telephones, microwave ovens, microwave terrestrial relay and satellite uplinks, and police, air traffic, and aircraft onboard radars. The authors report the strongest fields were found near industrial induction and dielectric heaters, as well as close to the radiating elements or transmitter leads of high power antenna systems. Handheld transmitters produced near fields of about 500 V/m at the antenna. Fields in the general urban environment were principally associated with radio and TV broadcast services and measure about 0.1 V/m. Peak fields from air traffic radars sampled in one urban environment were about 10 V/m, although the average value was 0.03 V/m when the duty factor associated with antenna rotation and pulsing were factored.
