The debate about whether wifi is dangerous or not continues.
A recent expert review of Canadian safety limits for exposure to radio waves—including waves from cellphones and wireless networks—suggests current limits are adequate, but recommends further research to potentially connect wifi with cancer and other health problems.
The Royal Society of Canada produced the report, titled “Expert Panel Report on the Review of Safety Code 6: Potential Health Risks of Radiofrequency Field.”
“If substantial cancer risks are demonstrated in a future study, then increasing the safety margin … would be warranted,” the eight-member panel concluded in a report released on Tuesday. “The current evidence is not strong enough to warrant doing so at present.”
“This potentially impacts a lot of people. That’s why we have to pay close attention to these studies as they come out,” said panel chair Paul Demers, a professor of public health at the University of Toronto and director of the Occupational Cancer Research Centre. Dr. Demers said he was confident that the panel had conducted a thorough and a balanced assessment of the available science.
Researchers at the US National Institutes of Health found in 2011 that an hour-long cellphone call increased glucose metabolism in subjects’ brains, which is a marker for increased cell activity. However, a subsequent study found the opposite effect.
