An Evaluation on Electrical Shock and Ignition Hazards in Metallic Structures Acting Receiving Antennas of Radio-frequency Radiation

고주파 방사에 대한 수신 안테나로 작용하는 구조물에서의 전격 및 점화 위험성 평가

Close to high power radio/radar transmitters, there is a possibility that electrical sparks may occur at discontinuities in metallic structures. If these structures are in an area where flammable mixtures are present, there is a danger that fire or explosion may happen by these sparks. Voltage may be induced on these metallic structures by the radio-frequency transmitter. In this case, a person who comes into contact with these structure may be undergone a severe electrical shock. In this paper, assessment of the these hazards was investigated through experimental and evaluation for actual tower cranes near AM radio transmitters.
