Measurement and analysis of power-frequency magnetic fields in residences: Results from a pilot study
Abstract
Overview
This study examines the exposure to extremely low-frequency magnetic fields (ELF-MFs) from various sources in residential environments, highlighting the need for high-quality assessments of ELF-MFs to inform better public health practices and reduce adverse health outcomes.
Subject and Methods
- Analysis of ELF-MFs from 3163 datasets in 100 houses across Australia, assessing compliance with the International Commission on Non-Ionizing Radiation Protection (ICNIRP) Guidelines.
- Comparison with 23 peer-reviewed studies to map out a broad understanding of magnetic field exposure in residential settings.
Findings
Magnetic field values varied across different residential locations, with considerable exposures noted near appliances and areas where individuals spend extended periods such as beds and bedrooms. Highlights include:
- Higher exposure levels observed near beds, bedrooms, and baby cots with a significant percentage exceeding ICNIRP guideline exposure levels.
- Spatial variations in magnetic fields across family rooms and children's play areas.
- Potential health risks associated with chronic exposure, particularly in sleeping areas.
Conclusion
The study establishes a new model for future data collection on ELF-MFs in residential areas, potentially aiding larger epidemiological studies and providing data for public use, especially for those without access to measurement tools. Recommendations include adopting simple precautionary measures to reduce ELF-MF exposure, thus minimizing health risks.
