People are often concerned when considering the purchase of a home near high-voltage power lines. A common question is: how close is too close?
In the past, we provided general distance guidelines on our website. Over the years, however, we have learned that distance alone does not tell the full story. The only reliable way to determine EMF levels is through on-site testing with highly accurate equipment.
Proper measurement is essential. EMF levels can vary significantly depending on factors such as the type of power line, electrical load, nearby wiring, and even conditions within the home itself. We follow a proven testing protocol to ensure measurements are accurate, thorough, and meaningful.
The bottom line is simple: rather than guessing based on distance, it is best to have an experienced professional perform the testing so you know exactly what levels are present.
According to widely recognized precautionary guidelines, magnetic field levels in living areas should ideally be well below 1 mG, with bedroom levels kept as low as reasonably possible. There are also recommended limits for electric fields, which should be evaluated separately according to third-party trusted guidelines.
Many people are surprised to learn that elevated EMF levels are sometimes found in homes that are nowhere near major high-voltage transmission lines. In some cases, the source may be household wiring issues, nearby distribution lines, or other electrical infrastructure.
