Abstract

Overview

The study focuses on the varied effects of electromagnetic field (EMF) exposure in mobile communication systems on the human brain. Particularly, it addresses the uncontrolled variables in real-world environments such as body position and EMF source direction.

Findings

  • Evaluation of the time-averaged specific absorption rate (SAR) of the human brain across a broad frequency range (50-5800 MHz).
  • Analysis incorporates variable factors including the number of EMF sources, incidence directions, and polarizations.
  • Results based on data measured in Seoul, end of 2021, describing the SAR and daily specific energy absorption (SA) in children and adults caused by exposure from 3G to 5G base stations.

Conclusion

The comparative analysis reveals that the specific absorption from downlink exposures in mobile networks is significantly higher than the uplinks, showcasing a notable link to potential health risks due to higher EMF exposure.
