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.
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.

“The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy (or equivalently, by virtue of the relations in the previous section, according to frequency or wavelength).”
Regions of the Electromagnetic Spectrum
“The following table gives approximate wavelengths, frequencies, and energies for selected regions of the electromagnetic spectrum.”
|Spectrum of Electromagnetic Radiation|
The notation “eV” stands for electron-volts, a common unit of energy measure in atomic physics. A graphical representation of the electromagnetic spectrum is shown in the figure below.
|The electromagnetic spectrum|
“Thus we see that visible light and gamma rays and microwaves are really the same things. They are all electromagnetic radiation; they just differ in their wavelengths.”
The Spectrum of Visible Light
The visible part of the spectrum may be further subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as illustrated (schematically) in the following figure.

"...............................I prefer wired communication over wireless. Most secure of all is voice/data transmissions over fiber optic cabling. But,..... I can't exactly say I've heard of a ton of cases where someone had fiber op installed in their home. But just to mention in case you din't already know, what makes communications over fiber so secure is the fact that is communication using laser optics (light) technology rather than transmissions superimposed on electical signals send over a twisted pair of copper wire. Also, fiber optic cabling is completely free from the electical interference that can plague twisted copper pair cabling. And, since all transmissions over fiber optics are always of the digital transmission type, sound clarity is superb. What's more, even if someone tried to tap your line by splicing into fiber optic, much like they can with copper pair wiring, that won't work. After all, it's light, not electricity used to transmit the voice/data connections. Actually, fiber op can even carry digital broadcast or cable TV transmissions....
