EMF: How close is too close?

E.M.F. Three little letters that strike terror into many hearts, but why?

EMF testing

Donna Shay, a Colorado citizen, asked Western to conduct an electric and magnetic field reading at her cabin that sits just outside a 115-kilovolt transmission line’s right-of-way. EMF readings determined about 1 milliGauss of exposure near her front door.

Mostly, it’s because we don’t understand electric and magnetic fields, or EMF.

The truth is people come into contact with these fields every day. EMFs occur naturally, like the magnetic field caused by currents deep inside Earth’s molten core. Manmade fields are also created by common appliances and equipment we depend on every day, like talking on a cell phone or heating up lunch in a microwave.

At Western, our high-voltage transmission lines and substations give off EMF, which sometimes concerns landowners with lines over and near their property. To help allay concerns, Western’s electrical engineers will test landowners’ EMF exposures from our transmission lines on request. Read more »
