Population Density and DL EMF Exposure Levels by Region in Korea

In 2023, the electric field strength within mobile communication bands was measured in the largest city (Seoul), a small city (Gwangju, Gyeonggi province), and a rural area (Yangpyeong, Gyeonggi province) in South Korea. The three measurement regions were selected based on population density; The population densities of Seoul, Gwangju, and Yangpyeong are about 15,550/km², 856/km², and 133/km², respectively. Measurements were performed by mounting the SRM3006 antenna on the roof of a vehicle and driving for approximately 40 km in each region. In this paper, the authors report the results of analyzing downlink RF-EMF levels in mobile communication networks currently in operation by frequency, time, and region.
