You can't see it, taste it, or smell it. The only way to know how much radon is in your home is to test for it with a long-term radon test kit.

Radon is the second leading cause of lung cancer. Radon is a radioactive gas that comes from the natural breakdown of uranium. All homes have some level of radon. The question is, how much? You can't see, taste, or smell radon. The only way to know how much radon is in your home is to test for it.
As radon breaks down it forms radioactive particles that can get lodged into your lung tissue as you breathe. The radon particles release energy that can damage the cells in your lungs. When the cells in your lungs are damaged, there is the possibility of developing lung cancer. Radon is the second leading cause of lung cancer and Canada is a hot spot! #ProtectYourFamily
Most of the time the air pressure inside your home is lower than the pressure in the soil surrounding your home’s foundation. This difference in pressure can draw air and other gases in the soil, including radon, into the house. Gas containing radon can enter your home at any opening where the house contacts the soil. These openings can be present any home, new or old.
Testing is easy and inexpensive. We offer long-term radon test kits called alpha track detectors which are approved by Health Canada. Radon levels in a home change over time. They can increase and decrease from one day to the next. For this reason, testing over a longer period of time is most accurate. Health Canada recommends that home owners do a long-term radon test, for at least three months, during the fall or winter months. Place the detector in the lowest area of the home where you or a member your family spends on average four hours each day. Testing instructions are included in your test kit. #TestYourHome

Health Canada Radon Guidelines and the latest research recommends that in order for test results to be both accurate and reliable, it is important to use a certified long-term (minimum of 3 month) radon test kit. Some retailers sell short-term radon test kits that are not supported by evidence-based best practices and guidelines.

There is no completely safe level of radon. Home owners are encouraged to reduce radon levels to be as low as reasonably possible. The Canadian Guideline for radon in indoor air is 200 Bq/m3 (becquerels per cubic metre). #KnowYourNumber

Techniques to lower radon levels are effective and can save lives. Radon levels in most homes can be reduced by more than 80% for about the same cost as other common home repairs such as replacing the furnace or air conditioner.

If your radon levels are high, we can help connect you with a certified radon reduction expert.


The Lung Association thanks Kerri and her family for courageously sharing Kerri's radon story. We are always looking for Radon Ambassadors. We would love for you to inspire others to take action on radon and ultimately help prevent lung cancer.
