“Teachers have warned that not enough is known about the effects of wi-fi.”
“Alan Johnson is said to believe that no investigation is required into the effects of wi-fi.”
“The use of wireless computer networks in classrooms should be immediately suspended until an inquiry has fully investigated the health threat to millions of pupils, a teachers’ chief urged yesterday”….” children were effectively acting as guinea pigs because the risk posed by ‘wi-fi’ networks had not yet been thoroughly considered.”….Wireless technology has been linked with loss of concentration, fatigue, reduced memory and headaches. There are also claims that it could increase the long-term risk of cancer.:
“My real concern is that until there is a full inquiry based on both existing evidence and on newly commissioned research work, the nation’s children are being treated as guinea pigs in a large-scale experiment.”…demand…an inquiry follows a similar call…a review of the health effects of wi-fi networks was ‘timely’ amid fears they could pose greater dangers than previously thought.”
“Wi-fi systems use high frequency radio waves to transmit and receive data over distances of several hundred feet….They allow users to surf the internet within range of a wireless transmitter and remove the need to connect via a cable….Some 70 per cent of primary schools and 81 per cent of secondaries have already introduced wi-fi, according to official figures, and it is being fitted as standard in all new state schools, including academies.”
“A typical comprehensive has ten wi-fi transmitters spread around the premises. If a school has thick walls, there may be many more. Children are thought to be more vulnerable to electro-magnetic radiation due to their thinner skulls and still-developing nervous systems”….”a wi-fi network… comprehensive gave off three times as much radiation as a typical phone mast, though some scientists have queried the programme’s claims.”
‘Guidance circulated …on schools to dismantle wi-fi networks immediately and replace them with cables. If this is impossible, they should measure radiation levels around the school and put warning signs at hotspots.’…a classics teacher, became too ill to teach after suffering headaches, pains, flushes, pressure behind the eyes and nausea. He has since conducted a study of research into electro-magnetic radiation and believes official advice on wi-fi is “inaccurate”…..dangers of children using wi-fi-enabled laptops on their knees, when the wi-fi transmitter would be only 2cm from the child’s body”…”It is widely used in homes, offices and in public areas.”

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.

“Mobile telephones, television and radio transmitters and radar produce RF fields. These fields are used to transmit information over long distances and form the basis of telecommunications as well as radio and television broadcasting all over the world. Microwaves are RF fields at high frequencies in the GHz range. In microwaves ovens, we use them to quickly heat food.”"At radio frequencies, electric and magnetic fields are closely interrelated and we typically measure their levels as power densities in watts per square metre (W/m2).”
- The electromagnetic spectrum encompasses both natural and human-made sources of electromagnetic fields.
- Frequency and wavelength characterise an electromagnetic field. In an electromagnetic wave, these two characteristics are directly related to each other: the higher the frequency the shorter the wavelength.
- Ionizing radiation such as X-ray and gamma-rays consists of photons which carry sufficient energy to break molecular bonds. Photons of electromagnetic waves at power and radio frequencies have much lower energy that do not have this ability.
- Electric fields exist whenever charge is present and are measured in volts per metre (V/m). Magnetic fields arise from current flow. Their flux densities are measured in microtesla (µT) or millitesla (mT).
- At radio and microwave frequencies, electric and magnetic fields are considered together as the two components of an electromagnetic wave. Power density, measured in watts per square metre (W/m2), describes the intensity of these fields.
- Low frequency and high frequency electromagnetic waves affect the human body in different ways.
- Electrical power supplies and appliances are the most common sources of low frequency electric and magnetic fields in our living environment. Everyday sources of radiofrequency electromagnetic fields are telecommunications, broadcasting antennas and microwave ovens.”
