83% of office workers near transformer stations face magnetic field exposures linked to leukemia risk in epidemiological studies.

Plain English Summary

Summary written for general audiences

Turkish researchers measured magnetic field exposure for office workers in buildings above or near electrical transformer stations and enclosures. They found 83% of workers were exposed to levels above 0.2 μT, which epidemiological studies have linked to increased leukemia risk. The highest measured exposure was 6.8 μT, significantly above typical home background levels of 0.3 μT.

Why This Matters

This study reveals a concerning reality for thousands of office workers whose buildings share space with electrical infrastructure. The science demonstrates that 83% of these workers face daily exposures exceeding the 0.2 μT threshold that epidemiological research has associated with elevated leukemia risk. What makes this particularly troubling is how common this building design has become in urban areas where real estate is expensive. The measured levels up to 6.8 μT represent exposures more than 20 times higher than typical home environments. The reality is that most of these workers have no idea they're being exposed to these elevated magnetic field levels during their 8-hour workdays. This represents a significant occupational health issue that building owners and employers should address through proper EMF assessments and, where necessary, relocating workspaces away from electrical infrastructure.

Quick Questions About This Study

Magnetic field levels ranged up to 6.8 μT in offices above or near transformer stations, with 75% of measurements exceeding 0.3 μT background levels and an average exposure of 1.19 μT.
83% of office workers in buildings with transformer stations or electrical enclosures were exposed above 0.2 μT, the level epidemiological studies associate with increased leukemia risk.
Yes, 75% of office measurements exceeded 0.3 μT home background levels, with some areas reaching 6.8 μT - more than 20 times typical residential exposure.
Two national banks and one industrial company with over 500 employees each showed elevated magnetic fields, with the highest single measurement reaching 6.8 μT near electrical infrastructure.
While measured levels stayed below occupational safety limits, 83% exceeded the 0.2 μT threshold that epidemiological research has linked to increased leukemia risk in long-term studies.
