My parents bought a house and the EMF readings are really high. It seems that the source is outside the home in a certain direction. How can we find out what the source is and what can we do to protect ourselves from the EMF? Also, are there professionals that deal with this? What is their professional title?

What kind of electric field, magnetic field, or electromagnetic wave are you talking about? How and why were they measured? If you are talking about electromagnetic interference (also called radio frequency interference, or RFI), there are plenty of tools, starting with the old fashioned transmitter hunt. Carry a receiver tuned to the interfering frequency, with a directional antenna. Use it to hunt down the sources. Is it entering the house via the power lines, phone lines, TV antenna or cable lines? Directly from a nearby antenna? Cable TV and masthead TV amplifiers are a common interference source. Your cheapest and friendliest help is likely to come from local ham radio operators, see arrl.org.

The most effective way of solving EMC problems is to pinpoint and reduce the actual sources of the interference. A very important method to tackle EMC problems already on chip-level is the so-called “surface scan method (IEC 61967-3)”. With this method the actual magnetic components, as well as the electric components of the electromagnetic field at the surface of the IC can be visualized. Using this method, the source of the electromagnetic emission of an IC can be located very easily.
