中波发射台周边电磁辐射监测与评价

目的 为正确了解中波台周边的电磁辐射水平，解决公众投诉、信访纠纷，为环保部门监管提供数据支撑。方法 采用对电磁辐射场强自动连续监测、瞬时监测、理论计算与实际监测相比对的研究方法。结果 对该中波台3 km范围内的监测数值可知，综合场强值的在2.08~13.59 V/m范围内，均在标准限值40 V/m以下。5年内，在其正常工作的情况下，中波台周边点位电场强度数值较平稳，没有明显变化。结论 从中波台周边电磁辐射水平来看，其周边3 km范围内未发现超标的监测点，未发现造成的电磁辐射污染。

Monitoring and evaluation of electromagnetic radiation from MW station

Objective In order to correctly understand the electromagnetic radiation level of MW integrated field intensities, solve public petition disputes, and provide data support for environmental protection department, this work was carried out.Methods The methods of automatic continuous monitoring, instantaneous monitoring, theoretical calculation and actual monitoring comparison of electromagnetic radiation intensities were adopted.Results The monitoring values within 3km around the MW showed that the electric field strength was in the range of 2.08~13.59 V/m, which are below the standard limit of 40 V/m.In 5 years, in the normal working conditions, the integrated field intensities of the points around MW were relatively stable and there was no significant change.Conclusion From the perspective of the electromagnetic radiation level around MW, no monitoring point exceeding the standard was found within 3 km, and no electromagnetic radiation pollution was found.
