Electropollution has a language all its own. Among some of the commonly used terms are:
Atom. The smallest component of an element that has all its properties and can exist alone.
Current. A flow of electrically charged particles.
Electromagnetic field. Currents create magnetic fields around themselves. If the current flows backwards and forwards far enough and for a long enough distance, then electromagnetic energy will move away at the speed of light.
Electron. A subatomic particle with a negative charge. Electrons usually orbit around atoms and are attracted by protons -- subatomic particles that carry positive charges.
Frequencies. The number of times an electromagnetic field changes direction per second, per minute or per other unit of time.
Hertz. A unit of frequency measuring cycles of electricity per second. One hertz is like one complete wave in the ocean.
Ions. Atoms that have negative or positive charges because they have unequal number of electrons and protons.
Ionizing radiation. Electromagnetic energy that generates ions by knocking electrons from the orbit of atoms. Includes cosmic rays, gamma rays and X-rays, all of which have a very high frequency.
Nonionizing radiation. Electromagnetic fields that oscillate at a slow rate and are unable to knock electrons from the orbit of atoms. Nonionizing radiation includes visible light waves, infrared, television signals, radio waves, short waves, extremely-low-frequency (ELF) waves and even ordinary household alternating current (AC).
Radiation. Energy emitted as particles or waves.
Watt. A unit of electrical power.
Volts. An expression of how hard electrons are pushed through a wire; a measure of electricity's pressure.
