Radon: The invisible threat that many Canadian households aren’t aware of
Radon is a radioactive gas that you cannot see, smell or taste, and it can get into your home undetected. It can be a health hazard when it enters enclosed spaces in your home, typically through cracks, openings in the foundation or gaps around pipes, and accumulates to a high level. Long-term exposure to radon is the leading cause of lung cancer in non-smokers.
