Radon is a naturally occurring, radioactive gas that comes up from the ground and can build up inside a home to dangerous levels. It has no color, no smell, and no taste, so testing is the only way to know if it's a problem.
​
Radon testing measures the concentration of radon gas in a home over a set period, usually 48 hours, using a calibrated monitor. The EPA recommends taking action if levels come back at or above 4.0 pCi/L, though many experts consider even lower readings worth addressing.

Why Test for Radon
The EPA and the U.S. Surgeon General identify radon as the second leading cause of lung cancer in the United States, after smoking, and the leading cause among non-smokers. Radon can enter a home through cracks in the foundation, gaps around pipes, and other openings, and levels can vary significantly from one home to the next, even between neighboring properties. Testing is the only way to know what's actually in the air you're breathing.

Who Should Test
Radon testing is a smart step for homebuyers before closing, for sellers who want to address the issue before it becomes a negotiating point, and for anyone who has never had their current home tested. Radon levels can also change over time as a home settles or as renovations affect airflow, so even a home tested years ago may be worth testing again.
