Abstract

Overview

The study explores the impact of electromagnetic (EM) technologies used in military applications, focusing on the exposure of crew personnel to high EM fields from vehicular antennas.

Methods

  • Evaluation of EM exposure in the presence of an HF vehicular antenna ranging 2–30 MHz.
  • Numerical simulation of a typical exposure scenario with a monopole antenna connected to a 3D polygonal vehicle structure.
  • Use of the Duke virtual human body model to simulate the operator partially outside the vehicle.
  • Measurements consider both EM field levels and specific absorption rate (SAR) values.
  • Assessment also involved modeling a protective helmet.

Findings

  • E-field intensity in areas occupied by crew personnel may exceed international safety guideline limits.
  • Local SAR values have a maximum of 14 mW/kg, while whole-body and 10-g averaged values remain within safety limits.

Conclusion

The simulation confirms significant potential EM field exposure, though specific absorption rates inside the human body are below critical safety thresholds. In-depth assessments are crucial to ensure the well-being of military personnel using EM technologies.
