Abstract

Overview

The study examines the exposure levels of electromagnetic fields (EMF) in urban Beijing, highlighting potential health threats and impacts on electronic systems.

Measurements and Findings

  • Measurements conducted along approximately 400 km of urban roads in Beijing.
  • About 89% of sampled points showed electric field strengths within safe limits (3 V/m). However, certain areas exhibited higher levels, sometimes exceeding national standards.
  • The association between electric field strength and factors such as population density and building density was analyzed using data mining techniques.
  • Lower EMF exposure typically found in areas with medium or lower population density and low building density. Conversely, higher exposure levels (1.5-4 V/m) were prevalent in densely populated and built-up areas, with values above 4 V/m in areas of extremely high population density.

Conclusion

Recommendations include intensified EMF monitoring in high-density areas and continuous monitoring of urban EMF trends to manage and mitigate potential health risks effectively.
