Instruments and Measurement Techniques to Assess Extremely Low-Frequency Electromagnetic Fields

Abstract

Category: Instrumentation and Measurement Tags: ELF-EMF, measurement, occupational exposure, instrument selection, health risk, regulatory compliance, weighted scoring matrix DOI: 10.3390/s25154866 URL: mdpi.com Overview This study presents a comprehensive evaluation and selection framework for extremely low-frequency electromagnetic field (ELF-EMF) measurement instruments. Recognizing the diversity of application environments and technical constraints, the framework addresses the challenges of selecting appropriate tools for specific scenarios. It integrates a structured, quantitative approach through a weighted scoring matrix that evaluates instrumentation across six criteria: - Monitoring duration - Sensitivity - Environmental adaptability - Biological/regulatory relevance - Usability - Cost Findings Complementing this is a logic-based flowchart that visually guides decision-making based on user-defined operational needs. The framework is applied to a realistic occupational case study, demonstrating its effectiveness in producing evidence-based, scenario-sensitive instrument recommendations. Conclusion This method provides stakeholders with a transparent and adaptable tool for ELF-EMF device selection, an important step in occupational safety and public health, especially given the connection between electromagnetic fields and potential health risks.
