| Objective To provide data support for control method of electromagnetic radiation hazard in low frequency communication system. Methods Based on IEEE-Std-C95.1-2005, GJB5313A-2017 and GB8702-2014, the near field integrated field intensity of antenna in low frequency communication system was obtained in details under different power and frequency conditions, and the working area was divided into dangerous zone, short-time activity zone and secure working zone. Results The range of 40 meters radius with the center of the rhombus antenna was the dangerous zone as the peak field intensity in which was higher than 70 V / m; the range of 40 to 70 M was a short-term activity zone; and the range outside 70 meter radius was the secure working zone. Conclusion Test verification and area division of near field electromagnetic radiation from low frequency antenna can provide technical support for the effective control of electromagnetic radiation hazards generated by the low frequency communication system. |
