Understand your number and your next step
A radon result of 4.0 pCi/L or higher can be alarming, but it's common in the Omaha area and very fixable.
Put your number in context
- The EPA action level is 4.0 pCi/L; the EPA also suggests considering mitigation between 2 and 4.
- The World Health Organization suggests a reference level of about 2.7 pCi/L.
- Results vary by season and weather. A single short-term test is a snapshot.
Should you retest?
If your first short-term test was between 4 and roughly 8 pCi/L, a second short-term test or a long-term test can confirm. If it's well above that, the EPA suggests moving forward with mitigation after a confirming test. In real estate, one professional test is often used to decide.
What happens next
A licensed contractor visits, evaluates the foundation, quotes a system, and installs it, often in a single day. A follow-up test confirms the reduction.
