Public concern about living near high-voltage power lines primarily centers on the electromagnetic fields (EMF) they produce and their potential health effects. It's important to understand that EMFs are a natural part of our environment and are also emitted by many common household appliances, such as microwaves and refrigerators.

Extensive research has been conducted on this topic for decades by leading health organizations worldwide, including the World Health Organization (WHO). The general consensus is that there is no conclusive scientific evidence linking the low-level EMFs from power lines to adverse health effects. The World Health Organization has classified extremely low-frequency magnetic fields (the type from power lines) as "possibly carcinogenic to humans" (Group 2B). It is important to note that this is the third-lowest of four classifications and is based on a limited statistical association with childhood leukemia found in some studies, not a proven causal link. Other things in this same category include pickled vegetables and aloe vera extract.

The key takeaway from the scientific community is that while it is impossible to prove a negative (that there is no risk at all), the current body of evidence does not substantiate a direct health hazard from exposure to the EMF levels typically found near transmission lines.
