Radon is an invisible radioactive gas that comes from the ground and is in every home in Canada. It’s the #1 cause of lung cancer in non-smokers. You can't smell, taste or see radon. But it's easy to test for and easy to reduce to safe levels.
When you test your home for radon, you’re planning to avoid the entirely preventable lung cancer that’s caused by radon exposure.
