People are increasingly exposed to electromagnetic radiation with the rapid development of technologies such as broadcasting and mobile communication system. There is a concern that long-term exposure at low levels may be associated with various non-specific physical symptoms and ecological effects on animals and plants. It is extremely important to measure and analyze the electromagnetic radiation levels in order to protect people from the possible effects of electromagnetic radiation. A large-scale assessment of the effects of electromagnetic radiation on health or on ecology requires the ambient electromagnetic radiation levels over areas too vast to cover with conventional measurement methods. In this article, detailed information about the measurement tools and measurement method are given. The electromagnetic radiation exposure levels were measured on the main streets in the dense urban areas of Beijing, the capital of China. We apply ordinary kriging as an interpolation technique to assess the electromagnetic radiation exposure in large outdoor areas based on car-mounted measurements along the surrounding roads. The electromagnetic radiation exposure levels for larger areas can be investigated visually on the electromagnetic pollution map, which can assist decision makers by identifying the hotspots.
随着广播和移动通信系统等技术的迅速发展，人们越来越多地暴露于电磁辐射中。有人担心，长期低水平暴露可能与各种非特异性身体症状以及对动植物的生态影响有关。为了保护人们免受电磁辐射的可能影响，测量和分析电磁辐射水平极为重要。对电磁辐射对健康或生态的影响进行大规模评估，需要测量传统测量方法难以覆盖的广大区域的环境电磁辐射水平。本文给出了有关测量工具和测量方法的详细信息。在中国首都北京人口密集的城市地区的主要街道上测量了电磁辐射暴露水平。我们应用普通克里金法作为一种插值技术，基于沿周边道路的车载测量来评估大型户外区域的电磁辐射暴露。可以在电磁污染图上直观地研究更大区域的电磁辐射暴露水平，这可以通过识别热点来帮助决策者。
