AUDIO: Wi-Fi health data reassuring: risk expert

Can Wi-Fi make childrensick?

A group of parents in Ontario's Simcoe County is blaming radiation from Wi-Fi inclassrooms for causing headaches, dizziness and nausea in their children. They want it shut off before school starts.

TheSimcoe County District School Board and theElementary Teachers' Federation of Ontario have rejected the parents' request, saying there is no scientific or medical evidence to show such wireless networkscan cause those symptoms in children.

Dan Krewski, director of the McLaughlin Centre for Population Health Risk Assessment at the University of Ottawa,told CBC Radio's Metro Morning thatso far, the medical evidence is reassuring. There have been thousands of research papers on the potentialhealth effects of the type of radiationemitted byWi-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,thinksparents are right toworry. Heshared his take onthehealth risks of the radiation emitted by Wi-Fi.
