Abstract
To develop a structured, risk-based framework for evaluating electromagnetic safety and assessing occupational health risks for personnel operating in the vicinity of military radar systems, in compliance with internationally recognized exposure standards. Operational data from representative radar systems were collected and three-dimensional antenna simulations were performed using CST Studio Suite 2024. Electric and magnetic field distributions, near- and far-field regions, and safe exposure boundaries were determined and post-processed in MATLAB. A three-dimensional human operator phantom was modeled to compute exposure metrics, including E- and H-field strengths, power density, and tissue-specific SAR, which were then compared against IEEE C95.1 and ICNIRP limits. A dedicated software tool (EMF Medical Surveillance) was used to quantify health risk indices and prioritize control measures. The results demonstrate that while the electromagnetic performance of the studied radar systems generally complies with international safety limits, certain long-term occupational exposure scenarios can lead to moderate to high health risk levels, highlighting the need for targeted health surveillance and enhanced control strategies. The study introduces an integrated, quantitative risk-based assessment framework that combines full-wave electromagnetic simulation, detailed human phantom modeling, and a decision-support software tool to link SAR-based dosimetry directly to occupational health risk classification and control prioritization for radar operators. The proposed framework enables the establishment of a systematic and risk-informed occupational health monitoring program aligned with electromagnetic safety standards. By focusing on realistic operational scenarios and exposure durations, it supports targeted personnel management and contributes to improving the operational safety of military radar systems.
