Employees of Brock University in St. Catharines, Ont., are being warned to be wary of Wi-Fi by a former member of the school's joint health and safety committee.

Prof. David Fancy, head of the drama department, took the unusual step of issuing a news release to warn staff about Wi-Fi dangers. Last year, he sat on a Brock subcommittee that looked into health issues involving electromagnetic safety, and came away with deep concerns.

"We came to the conclusion that unlike Health Canada's assertion that says that Canada's safety code protects us, we felt that there was more evidence out there to suggest that this isn't necessarily correct."

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.
