A second private school in Ontario has removed its Wi-Fi Internet system, citing health concerns, the latest move in a continuing public debate over the safety of wireless devices.

A group called the Safe School Committee said Tuesday that Wayside Academy in Peterborough, Ont., has done away with its wireless Internet, citing a declaration from the World Health Organization in May that microwave radiation from Wi-Fi and other wireless devices are a "possible carcinogen."

An International Agency for Research on Cancer study led to the classification in May of radio-frequency electromagnetic fields as "possibly carcinogenic" to humans, based on an increased risk of glioma, a malignant type of brain cancer, associated with wireless phone use.

The World Health Organization listed cellphones in the same "carcinogenic hazard" category as lead, engine exhaust and chloroform.
