Earlier this month, school administrators in Ontario’s Simcoe County decided not to turn off wireless internet in classrooms despite complaints from parents who suspect their children are being made ill by the Wi-Fi.
There’s a debate in the scientific community about whether radiation from wireless communications could pose health risks. Some studies suggest Wi-Fi may cause neurological and cardiac symptoms, but other researchers insist the concerns are unfounded.
Dan Krewski, director of the McLaughlin Centre for Population Health Risk Assessment at the University of Ottawa, told CBC Radio’s Metro Morning that so far, the medical evidence is reassuring. There have been thousands of research papers on the potential health effects of the type of radiation emitted by Wi-Fi and cellphones, he said, and overall, they show no cause for concern.
A day earlier, British physicist Barrie Trower had shared an opposite view with Metro Morning. Trower, who advised the British Secret Service on the use of microwave weapons during the Cold War, thinks parents are right to worry.
