You can’t see or smell radon, so what happens if your monitor gets it wrong?
Recent recalls of some radon detectors by Health Canada have raised concerns about inaccurate readings, and what that means for people trying to protect their homes.
Radon risk comes from long-term exposure, and levels can fluctuate daily, even hour to hour. That’s why experts recommend measuring over 90 days (or longer) to understand the bigger picture.
Using a reliable, accurate monitor is an important first step. Health authorities like Health Canada, the Environmental Protection Agency, and the American Lung Association all provide guidance on choosing a safe, trusted device.
