Personal exposimeter coupled to a drone as a system for measuring environmental electromagnetic fields

Abstract

Overview

Personal exposimeters are essential tools in assessing human exposure to electromagnetic fields (EMFs). Traditionally, these devices are either carried by individuals or mounted on moving vehicles like bicycles or cars. This study introduces an innovative approach by attaching a personal exposimeter to a drone, aiming to enhance environmental radio-frequency measurements.

Findings

• The interaction between the drone's remote controller and its communication does not negatively affect the relevant mobile telephony bands, suggesting no significant cross-talk effect.
• The structure of the drone can influence the measurements. However, this effect is quantifiable, allowing for accurate adjustments.
• A detailed 3D representation of the electric field around a building was achieved, demonstrating the drone's ability to measure vertical electric profiles effectively.
• The attenuation of radiation due to a building was estimated, highlighting potential EMF exposure risks from external sources.

Conclusion

Using drones equipped with exposimeters may significantly advance our capability to monitor EMF emissions near antenna sources safely and validate propagation models experimentally. This method also ensures minimization of human exposure risk during the measurement process.
