Radon is the second leading cause of lung cancer

Did you know that radon is the second leading cause of lung cancer?  Long term exposure to high levels of radon can increase a person's risk, especially if they smoke.

To mark Radon Action Month, Health Canada is encouraging all Canadians to become aware of this potential health risk and take steps (if necessary) to mitigate exposure.  For information on radon, including how to obtain a test kit, visit our website

Quick facts: Radon is a radioactive gas that is found naturally in the environment and is undetectable by smell, sight, or taste.
It can seep into a home through cracks in the foundation, pipe openings, and other places where a house is open to the ground.
The only way to know if it is there is through a simple and inexpensive test.  
You may purchase a "do it yourself" kit, or hire a professional (consult the National Radon Proficiency Program to find out more).

Health Canada recommends that homes be tested for a minimum of three months, ideally between September and April when windows and doors are kept closed. If your home tests above the Canadian Radon Guideline of 200 Becquerels per cubic metre (200 Bq/m³ ), it is recommended that you take action to reduce your exposure. The risk from radon is long-term (over decades).  The higher the level and the longer a person is exposed, the higher the risk of lung cancer, especially if they smoke.
