Abstract

Overview

This study investigates the electromagnetic field (EMF) exposures in the urban area of Beijing, China, highlighting the association between EMF exposure levels, population density, and building density.

Findings

  • Measurement of EMF was conducted along approximately 400 km of roads across Beijing.
  • Most (89%) of the sampling points showed electric field strengths within 3 V/m.
  • A particular section of road was found to exceed national standard limits of electric field strength.
  • An innovative set of procedures was developed to analyze the correlation between electric field strength and demographic/geographic factors.
  • Areas with high population and building density typically showed higher electric field strengths.

Conclusion

It is crucial to enhance EMF monitoring especially in densely populated areas to manage potential health risks effectively. Continued surveillance can facilitate early warning and proactive management of EMF-related health concerns.
