Radon is a radioactive gas that occurs naturally in the environment. It is created by the decay of uranium in soil, rock and water. It is an odorless, colorless gas that moves freely through the soil, allowing it to be released into the atmosphere and seep into buildings. In the open air, the amount of radon is minimal and does not pose a health risk. However, a significant accumulation of this gas in your building can cause certain risks. According to Health Canada, radon is the second leading cause of lung cancer after smoking.
