Photo: Is radon on your radar?

Radon is a radioactive gas produced by the natural decay of uranium in soils... and the leading cause of lung cancer among non-smokers.

Canadians are exposed to radon when it escapes from the ground into the air. Concentrations outdoors are low, but radon can become trapped and accumulate in buildings, reaching high levels. You can't see, smell or taste radon. The only way to determine whether radon levels are high in your house is to run a test.

The David Suzuki Foundation encourages governments and individuals to take action on radon. Read more about our policy recommendations in the 2015 report, Revisiting Canada's Radon Guideline, and test your home for radon.
