With news this week that full-body scanners will soon be installed in airports across Canada, many are wondering: could the scanners be a risk to my health?
The security devices are designed to keep travellers safe by helping to detect weapons strapped to the bodies of would-be terrorists. Not only can they spot knives and guns hidden under clothes, just as a metal detector can, they can also spot high-density materials, such as plastics and objects used in explosives.
What makes the scanners controversial is that they use radiation to generate their images. And that has some wondering whether they might be dangerous, particularly for children and pregnant women, especially since it's known that exposure to high levels of radiation can cause serious health problems such as cancer.
At least one expert believes there is nothing to worry about.
