A person exposed long-term to high radon levels has a 1 in 20 chance of developing lung cancer.

If there is also exposure to cigarette smoke, this risk increases to 1 in 3.

Radon is a naturally occurring radioactive gas that comes from uranium in the ground. It enters schools, homes and other buildings through cracks and gaps in building foundations. This colourless, odourless gas can build up to harmful levels in enclosed spaces.

Long-term exposure to high levels of radon is the second leading cause of lung cancer in Canada. It is the number one cause of lung cancer in non-smokers.

And unsafe exposure is entirely preventable.

Rule out radon.
