Definitions
The properties and effects of non-ionising radiations are very diverse. For the purpose of this Policy non-ionising radiations include:
Extremely low frequency (ELF) radiation
Electromagnetic radiation with frequencies in the range 0 Hz (static fields) to 3 kHz, including the 50 Hz electric and magnetic fields associated with the domestic mains electricity supply such as in domestic electrical appliances, electricity supply substations and overhead power lines.
Radiofrequency (RF) radiation
Electromagnetic radiation with frequencies in the range 3 kHz to 300 GHz, which is produced by artificial sources such as visual display units and mobile phones.
Microwave (MW) radiation
Electromagnetic radiation with frequencies in the range 1 GHz to 300 GHz, which is produced by artificial sources such as in microwave ovens and by microwave communication devices. (This radiation is now considered part of Radiofrequency radiation.)
Infrared (IR) radiation
Electromagnetic radiation with wavelengths between 700 nm and 1 mm, which is present in sunlight and produced by artificial sources such as electric radiator heaters.
Visible light
Electromagnetic radiation with wavelengths between 400 nm (blue) and 700 nm (red), which is present in sunlight and produced by numerous artificial sources, including lasers.
Ultraviolet (UV) radiation
Electromagnetic radiation with wavelengths between 100 nm and 400 nm, which is present in sunlight as well as produced by artificial sources such as arc welding and sterilization lamps.

What is a Negative, or Positive, Frequency? October 2, 2006

“The concept of negative and positive frequency can be as simple as a wheel rotating one way or the other way. A signed value of frequency indicates both the rate and direction of rotation. The rate is expressed in units such as revolutions (aka cycles) per second (hertz) or radians/second (where 1 cycle corresponds to 2π radians). By convention, a positive frequency is associated with rotation in the counterclockwise direction, whereas a negative frequency represents rotation in the clockwise direction.”
