EMFs - Electric and magnetic fields. This site will refer to fields from 60 Hz power.
Electricity - A form of energy created by the flow of current or the presence of voltage.
Current - The movement of an electric charge.
Voltage - The potential strength of electricity, or how much pressure there is in a line to move electricity.
Electric Fields - Invisible fields of force created by electric voltage. Electric fields are measured in volts per meter (V/m). The field is more intense when the voltage is greater and the closer to the source you are. Most objects block electric fields.
Magnetic Fields - Invisible fields of force created by electric current. Magnetic fields are measured in milligauss (mG). The field is more intense when the current is greater (i.e. when your electric stove runs on high versus low). Magnetic fields pass through most objects.
Frequency - the number of repetitions of an electric wave per second.
60 Hertz Power - The type of electric power that we use in North America, in which current alternates back and forth 60 times per second.
Epidemiology - A type of research that tries to find statistical links between the occurrence
of specific diseases and people's exposure to possible causes.
