Occupational Exposure to Extremely Low-Frequency Magnetic Fields and Risk of Amyotrophic Lateral Sclerosis: Results of a Feasibility Study for a Pooled Analysis of Original Data

This feasibility study reveals a critical gap in our understanding of occupational EMF exposure and ALS risk. While previous research suggested a connection between workplace magnetic field exposure and this devastating neurological disease, the methodological inconsistencies across studies have prevented definitive conclusions. The reality is that workers in electrical occupations, utility companies, and manufacturing facilities face daily exposure to ELF magnetic fields at levels far exceeding what most people encounter at home. What this means for you is that millions of workers may be unknowingly exposed to EMF levels that could increase their ALS risk. The willingness of eight research teams to share their data represents a rare opportunity to conduct the kind of rigorous, large-scale analysis needed to resolve this question. Given that ALS is invariably fatal and workplace exposures are preventable, we cannot afford to wait decades for absolute proof while workers remain unprotected.
