Study On Electromagnetic Radiation Problem Of Short Wave Transmitter Center

In recent years, people pay more and more attention to the problem of environmental protection, and the pollution problem caused by electromagnetic radiation is becoming more and more serious.By using the theory of electromagnetic field and electromagnetic wave, the electric field intensity around the antenna field is calculated. The field measurements were carried out on the electromagnetic environment of the antenna launching site and the short wave transmitter room. Based on the comparison of the field test and calculation results, the electromagnetic environment of the short wave transmitting station is discussed. After the calculation and real-time monitoring, The distance between the monitoring point and the antenna increases, and the intensity of the monitored electric field decreases.From the monitoring and software simulation of the data obtained in the distance from the antenna close to the next monitoring point, the electric field strength decay rapidly. The rate of decrease in electric field strength then tends to be steady.In the short-wave transmitter room, the distribution of electric field intensity also decreases as the distance between the monitoring point and the transmitter increases. In the scope of the activities of the staff of the launch station, the electric field strength of the station area basically accords with the relevant national standards, some of the electric field intensity points are near the feeder, in view of the feeder station layout in the transmitter area wider, Should cause the necessary attention. For the launch of the staff of electromagnetic protection should be reduced from the radiation source, reduce contact time, increase the radiation protection equipment and so on.
