Extremely Low-Frequency Magnetic Fields Exposure Measurement during Lessons in Elementary Schools
Abstract
Overview
Concerns about the potential health risks of electromagnetic fields (EMFs) are particularly relevant in educational settings. This study focuses on measuring extremely low-frequency magnetic fields (ELF-MFs) exposure levels in elementary schools during digital learning sessions.
Findings
- Numeric measurements of ELF-MFs were recorded using an EMDEX II field analyzer in multiple classrooms.
- Exposure levels were compared to International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines, finding that levels were generally compliant but varied across different schools and seating positions.
- Most ELF-MFs exposure at student seating positions was linked to nearby electrical appliances and wiring, with levels decreasing with increasing distance from these sources.
Conclusion
While exposure to ELF-MFs was within established guidelines, the variability and potential health risks warrant careful classroom design to minimize exposure. Further research is recommended to explore the broader impacts of ELF-MFs exposure on children's health and to develop effective exposure reduction policies.
