Magnetic fields, leukemia, and central nervous system tumors in Swedish adults residing near high- voltage power lines
Authors not listed · 1994
Living near high-voltage power lines doubled myeloid leukemia risk in Swedish adults exposed to magnetic fields above 0.2 microT.
Plain English Summary
Swedish researchers studied adults living within 300 meters of high-voltage power lines from 1960-1985, examining 325 leukemia cases and 223 brain tumor cases. They found that magnetic field exposure above 0.2 microT doubled the risk of certain blood cancers, particularly acute and chronic myeloid leukemia. Brain tumors showed no increased risk.
Why This Matters
This landmark Swedish study represents some of the strongest evidence linking power line EMF to adult cancers. The finding that myeloid leukemia risk more than doubled with cumulative exposure is particularly significant because it demonstrates a dose-response relationship - the hallmark of causation in epidemiology. What makes this research especially credible is its focus on calculated magnetic field levels rather than simple distance measurements, providing more accurate exposure assessment.
The 0.2 microT threshold identified here is crucial context for everyday exposure. While this level is typically found only very close to high-voltage lines, it's important to understand that many household appliances can produce similar or higher fields at close range. The key difference is duration - the Swedish residents experienced chronic, long-term exposure that most of us don't face from brief appliance use.
