Hello BuyingTips and other Real Estate Agents / Brokers,
I am a dedicated EMF inspection and testing professional and have been doing this longer than 10 years for hundreds of concerned homeowners and commercial businesses here in the Dallas - Ft. Worth area .
The short answer to your question about "how far away is safe" is that it is complicated as others have commented, and Mr. Bruce Lynn is correct about the amperage being a factor. The other is the geometry of the support towers and phasing between the lines and how it affects the resulting falloff gradient. I have seen much higher fields from a miswired 3 way switch than from some 238 keV feeders, so in short, you can never tell by looking.
I am not a fearmonger and I do not try to convert skeptics as I have an electrical engineering background and take the more dramatic claims with a grain of salt, though I do believe in providing data and context so that a client can see where along a continuum their home lies compared to others in general and to certain safety standards that have been chosen by different organizations. There is nothing like a bit of experience and knowledge to bring balance and peace of mind to what may look scary.
But as a parting thought, even if you do not believe in the ill effects of EMF, an inspection often turns up wiring errors that while not usually expensive to fix, are code violations that you might want to know about.
A lot of questions about an EMF inspection are answered on my FAQ page here at:
