Radon Detector Beeping: What the Alarm Means and What to Do

Sun, 09 Aug 2026 00:00:00 +0000

There’s a beeping device in your basement. It’s not the smoke detector, not the CO detector, and not the water leak sensor. It’s your radon detector — and it’s trying to tell you something about an invisible, odorless gas that you can’t see, smell, or taste.

Radon is the second leading cause of lung cancer after smoking, responsible for about 21,000 lung cancer deaths per year in the United States according to the EPA. It seeps into homes from the ground through foundation cracks, and the only way to know it’s there is to test for it.
