Radon is a radioactive gas found naturally in the environment. It is produced by the decay of uranium found in soil, rock or water. Radon is invisible, odorless and tasteless and emits ionizing radiation. As a gas, radon can move freely through the soil enabling it to escape to the atmosphere or seep into buildings. When radon escapes from the bedrock into the outdoor air, it is diluted to such low concentrations that it poses a negligible threat to health. However, if a building is built over bedrock or soil that contains uranium, radon gas can be released into the building through cracks in foundation walls and floors, or gaps around pipes and cables.


Radon gas causes lung cancer. On average 16% of all lung cancer deaths in Canada are caused by Radon gas, that is about 3,000 people per year. If you are a smoker your chances of lung cancer increase to 30% if you live in a house with elevated radon levels. Radon is the second leading cause of lung cancer, after smoking.


It's everywhere. It's not a question of whether or not you have Radon in your home. You do. It's in my house, it's outside, it’s all around us. The question is: How much? And the higher the level, the higher the risk. The risk from radon is long-term, it's not immediate. It's long term exposure; years and decades of exposure. The higher the level and the longer you're exposed to it, the higher the risk of developing lung cancer.


Health Canada recommends that all Canadian houses be tested. You test for a minimum of three months. The levels vary quite a bit over time, so you want an accurate representation of what you're breathing in, what you're being exposed to in your home over a long period of time.

There are simple ways of testing radon in your home. You should hire a certified radon professional to do the test for you.
