LOL! Electromagnetic fields, my azzzzz. They have know idea what an electromagnetic field is.
These guys should be more worried about sitting too close to their microwave.
Microwave? What do they think their Computer Monitor generates?
I do...I do! An electromagnetic field is a pasture where you allow electromagnets to graze and grow strong!
An engineer at my company lived in a neighborhood where the poser company wanted to raise the voltage on the lines to make up for the increased draw. The neighborhood was all in a tizzy about the "cancer risks [associated] with living near high-voltage utility lines". So naturally they turned to their resident engineer who goes out and borrows a Gauss meter and goes around taking readings to measure the EM strength around high tension lines.
The result was that you receive more EM radiation in front of a CRT than from standing directly beneath 160kV power lines. Being reasonable people, the neighbors shut up and allowed the power company to do as they wanted.
