广电传输发射中心电台改造后的现状监测及类比分析

Status monitoring and analogy analysis of radio and television transmission at the transmission center after reconstruction

广播电视传输发射中心电台发射天线会对周围环境产生一定的电磁辐射,为掌握电磁辐射污染源的辐射水平,保障辐射环境安全,通过对迁建改造后的广播电视台发射塔项目开展环境影响评价,对其发射装置产生的电磁辐射进行现状监测,同时对电台运行情况开展了环境监测,类比分析其电磁辐射影响水平.结果表明,所监测的电场强度值均小于公众曝露电场强度控制限值,说明周围的电磁辐射环境质量现状良好.

The transmitting antenna of the radio and television transmitting center can produce certain electromagnetic radiation to the surroundings.To grasp the radiation levels of the pollution sources of electromagnetic radiation and to ensure the safety of the radiation environment,an assessment of the environmental impact has been made for the radio and television transmission tower after its relocation and reconstruction.The current situation of electromagnetic radiation produced by the transmitter is monitored,the operation of the radio station is monitored,and the influence of electromagnetic radiation is analyzed by analogy.The results show that the intensity values if the monitored electric field are lower than the control limits of the electric field intensity of public exposure,indicating that environment quality of the surrounding electromagnetic radiation is in good condition.
