Warning to school kids on wi-fi Schools are introducing wi-fi into classrooms despite questions over the long-term safety of the wireless technology. AUSTRALIAN schools are introducing wi-fi into classrooms despite questions over the long-term safety of the wireless technology. The influential American Academy of Pediatrics has called for a review of radiation emissions from mobile phones and wi-fi, warning that existing safety limits are "not an accurate predictor of actual exposure." France has legislated to discourage wi-fi in schools until it is "safe for human consumption," Germany has recommended its schools use cabled computers and the Council of Europe has called for a ban on wi-fi in classrooms. In Israel, the Ministry of Education has told schools to use wired computers in classrooms, and requires teachers to turn off wi-fi routers when not in use. A group of concerned Australians Wi-fi in Schools is circulating a "non-consent" letter for parents to give to school principals if they do not want their children exposed to wi-fi in classrooms for six hours a day. "In order to minimise exposure to wireless radiation, we favour wired communications as a safer option until there is conclusive evidence that there are no harmful effects from long-term use," the group said. The federal government regulator, the Australian Radiation Protection and Nuclear Safety Agency, insisted wi-fi was safe in schools. But a member of the agency's Radiation Health and Safety Advisory Council, emeritus professor Ian Lowe, said he would ask the council to investigate wi-fi and mobile-phone emission standards for children. "You should not deploy technology, be it wi-fi in schools or diagnostic technologies, until you can be sure it is safe and cost-effective," he told The Sunday Times. Prof Lowe said the level of electromagnetic radiation from wi-fi was "very low." He said children would absorb more radiation from an electric blanket than from wi-fi. The American Academy of Pediatrics has told the US Federal Communications Commission that "children are not little adults and are disproportionately impacted by all environmental exposures, including cell-phone radiation." Tasmania's Education Department deputy secretary, Andrew Finch, said wi-fi in schools met Australian Communications and Media Authority standards and was "deemed to be safe."
