“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.”

“Biological effects of extremely low-frequency electromagnetic fields (ELF-EMF) on microcirculation were investigated in vivo by monitoring arteriole diameters in conscious mice. Measurements of blood vessel diameter were monitored 33 min non-stop before during and after exposure with ELF-EMF and every 389 ms blood vessel diameter were calculated….Since vessel diameters exhibit rhythmic variation expressed by vasomotion, for estimation of microcirculatory activity….. with the aim to evaluate possible changes in mean blood vessel diameter as a result of ELF-EMF action.”
“During EMF exposure and post-exposure periods, arteriole diameters increased significantly compared with the pre-exposure period, and the changes were larger during post-exposure. In contrast to sham exposure, vasodilatation of the microvasculature was significantly greater during exposure and post-exposure to 16 Hz EMF. These findings suggest that ELF-EMF may have potential therapeutic use benefit for treating vascular disorders.”

..”the human ear is capable of detecting sound waves with a wide range of frequencies, ranging between approximately 20 Hz to 20 000 Hz. Any sound with a frequency below the audible range of hearing (i.e., less than 20 Hz) is known as an infrasound and any sound with a frequency above the audible range of hearing (i.e., more than 20 000 Hz) is known as an ultrasound. Humans are not alone in their ability to detect a wide range of frequencies. Dogs can detect frequencies as low as approximately 50 Hz and as high as 45 000 Hz. Cats can detect frequencies as low as approximately 45 Hz and as high as 85 000 Hz. Bats, who are essentially blind and must rely on sound echolocation for navigation and hunting, can detect frequencies as high as 120 000 Hz. Dolphins can detect frequencies as high as 200 000 Hz. While dogs, cats, bats, and dolphins have an unusual ability to detect ultrasound, an elephant possesses the unusual ability to detect infrasound, having an audible range from approximately 5 Hz to approximately 10 000 Hz.”
