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.
What is a Ring Tone?

A ring tone is the sound made by a telephone to indicate an incoming call. The term, however, is most often used to refer to the customisable sounds available on mobile phones. This facility was originally provided so that people would be able to determine when their phone was ringing when in the company of other mobile phone owners.
A phone only rings when a special “ringing signal” is sent to it. For regular telephones, the ringing signal is a 90-volt 20-hertz AC wave generated by the switch to which the telephone is connected. For mobile phones, the ringing signal is a specific radio-frequency signal.
Malware is software designed to infiltrate or damage a computer system, without the owner’s informed consent. There are disagreements about the etymology of the term itself, the primary uncertainty being whether it is a portmanteau word (of “malicious” and “software“) or simply composed of the prefix “mal-” and the morpheme “ware”. Malware references the intent of the creator, rather than any particular features. It includes computer viruses, worms, Trojan horses, spyware, adware, and other malicious and unwanted software. In law, malware is sometimes known as a computer contaminant, for instance in the legal codes of California, West Virginia, and several other U.S. states.Malware should not be confused with defective software, that is, software which has a legitimate purpose but contains harmful bugs.
Whereas older telephones simply used a pair of bells for the ringer, modern ringtones have become extremely diverse, leading to phone personalization and customization.
Newer mobile phones allow the users to associate different ringtones for different phonebook entries. Many also allow users to create their own music tones, either with a “melody composer” or a sample/loop arranger…. Often these are native formats only available to one particular phone model or brand. However, other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ringtone. Commercial ringtones take advantage of this functionality, which has led to the success of the mobile music industry.
