What are Electromagnetic Fields (EMF)?
The word EMF is a general term that includes radio waves (electromagnetic waves with a specific magnetic:electric ratio of 1 milligauss:30 V/m), and an electric or magnetic field whether oscillating or not- even if it is a pure electric field such as from static electricity, or a purely magnetic field, such as from an electromagnetic (AC or DC) source. Radio Frequency (RF) is more specific than EMF.
In our modern world, we are exposed to EMF from a variety of sources: High Voltage Power Lines, Cellular Phone Towers, Electric Meters, WiFi Routers, and even common household appliances.
There are two types of fields that are of most concern: Magnetic and Radio Frequency.
