More Information About Radon

Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible, odourless and tasteless. When radon is released from the ground into the outdoor air, it is diluted and is not a concern. However, in enclosed spaces like homes, it can accumulate to high levels. High radon levels can be a risk to the health of you and your family.

• WHAT ARE THE HEALTH EFFECTS OF RADON?

  When radon gas is inhaled into the lungs it decays into radioactive particles that release small bursts of energy. This energy is absorbed by nearby lung tissue, damaging the lung cells. When cells are damaged, they have the potential to result in cancer when they reproduce. Radon exposure is the #1 cause of lung cancer in non-smokers. Exposure to high levels of radon in indoor air results in an increased risk of developing lung cancer. The risk of cancer depends on the level of radon and how long a person is exposed to those levels. Exposure to radon and tobacco use together can significantly increase your risk of lung cancer. For example, if you are a lifelong smoker, your risk of getting lung cancer is 1 in 10. If you add long‑term exposure to a high level of radon, your risk becomes 1 in 3. As a non‑smoker, your lifetime lung cancer risk at the same high radon level is 1 in 20

• HOW CAN RADON GET INTO MY HOME?

  Radon gas moves through the ground and escapes outside or into buildings. Radon can enter a home any place it finds an opening where the house is in contact with the ground: cracks in foundation walls and in floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sumps or cavities inside walls. 

• WHAT ARE THE RADON LEVELS IN CANADA?

  All homes in Canada have radon gas in them. Concentrations differ greatly across the country, but are usually higher in areas where there is a higher amount of uranium in underlying rock and soil. Radon levels will vary from one house to another, even if they are similar designs and next door to each other. No matter the age, type of construction or where your home is located, the only way to be sure of the radon level in your home is to test.
