电视、中波发射塔对电磁辐射环境的影响

通过对包头市城区历年的电磁环境监测,以及电视和中波发射塔周围电磁辐射情况,了解其环境质量状况和主要污染源。历年环境监测综合场强为0.30~0.47 V/m,年平均值为0.41 V/m。而广播和电视发射塔因距离而异,它们综合场强均值分别为1.26~3.43 V/m、1.44~5.34 V/m。虽然这些监测值都在标准限值之内,但可以看出广播和电视发射塔对电磁辐射综合场强的影响极大。

INFLUENCE OF TELEVISION TOWER AND MEDIUM WAVE TOWER ON ELECTROMAGNETIC RADIATION ENVIRONMENT

As human enjoy the convenience of the advanced technologies， electromagnetic radiation is gradually coming into ourliving space． By detecting the electromagnetic condition in the city of Baotou for many years，including the electromagneticradiation of TV and medium wave around the tower，the environmental quality and the main sources of electomagnetic radiationpollution． Integrated electromagnetic values range for environmental monitoring field is between 0. 30 V/m and 0. 47 V/m，theaverage annual value is 0. 41 V/m． Because the average value of integrated field strength of the radio and televisiontransmission towers is differentiated by the distance，ranges from 1. 26 to 3. 43 V/m and from 1. 44 to 5. 34 V/m，seperately．These monitoring values are within the standard limits． However，it can be concluded that the high impact of the radio andtelevision transmission towers on the electromagnetic radiation environment．
