Abstract

Abstract Summary: Exposure to Radio-Frequency Electromagnetic Fields

Overview

This study explores the critical yet under-researched topic of human exposure to radio-frequency electromagnetic fields (RF-EMF) from vehicular connectivity. The research focuses specifically on RF-EMFs generated by vehicle-to-vehicle (V2V) communication antennas.

Methodology

The analysis was conducted using computational dosimetry on a 3D numerical model which included a car equipped with two V2V antennas and an adult human model simulating a road user near the vehicle. Each antenna was fed with 1 W, operating at 5.9 GHz.

Findings

• The highest specific absorption rate (SAR) was observed in the skin of the head (34.7 mW/kg) and in the eyes (15 mW/kg).
• Comparatively, SAR levels in the torso and limbs were notably lower or negligible.
• Overall, the whole-body SAR was calculated to be 0.19 mW/kg.
• Importantly, all observed SAR values were significantly below the international safety limits set by the ICNIRP for the 100 kHz-6 GHz band.

Conclusion

The study successfully demonstrates a method to assess RF-EMF exposure using V2V communication systems under various scenarios. This technique can be extended to different setups and age groups to further understand electromagnetic safety.
