Radon and lung cancer

After smoking, radon is the leading cause of lung cancer in Canada and is responsible for as many as 16% of lung cancer deaths.


Radon is a radioactive gas that occurs when uranium in soil and rock breaks down. You can’t see it, smell it, or taste it. In enclosed spaces, such as a home, it can accumulate to dangerous levels.  The only way to know if your home has a radon problem is to test. 

To learn about radon, how and when to test for it, and how to protect yourself against radon health risks, consult our RadonAware website. A branded public education and advocacy program, RadonAware was established by the BC Lung Association and provides research, information, education and advocacy on issues related to reducing the lung cancer risk caused by radon.
