Radon Result Calculator FAQs
What radon level should I act on?
The EPA recommends fixing your home at 4.0 pCi/L or higher, and suggests considering mitigation between 2.0 and 3.9 pCi/L. There is no known safe level of radon, so lower is always better.
Should I trust a single short-term test?
A short-term test is a good first look, but radon moves with the seasons and the weather. If your result is near a decision point, a follow-up test or a long-term test gives you a better picture of your year-round average.
How low can a mitigation system bring my radon level?
Our systems routinely bring homes with readings above 4.0 pCi/L down below 1.0 pCi/L, with up to 98.9% reduction. A post-mitigation test confirms the result after the install.
