Monitoring of the exposure to electromagnetic fields with autonomous probes installed outdoors in France

Abstract

Overview

The study employs a novel temporal analysis approach to monitor electromagnetic field (EMF) exposures across various French cities. This is executed through autonomous broadband E-field monitoring probes in conjunction with frequency-selective measurements and insights into nearby base station antennas.

Findings

• The data illustrates varying exposure levels with identifiable patterns such as seasonality and day-to-night variations.
• Significant findings include the revelation of day and night exposure differences using the said monitoring probes, a first in France.
• An empirical interval from 8 AM to 11 PM was used for detailed analysis, showing a ratio of averaged E-field levels between day and night ranging between 1.28 and 1.42 for probes with the highest RMS levels.
• The study confirms that both the positioning of probes and their proximity to base stations are crucial for accurate readings.
• It was noted that probes installed away from base stations in low-density areas generally recorded lower exposure levels.

Conclusion

The deployment of autonomous monitoring probes offers a robust methodology for analyzing EMF exposure. Probes not only detect variations but also provide crucial data aiding in understanding the impact of environmental factors like base station proximity and urban density on exposure levels.
