Where Zone 1 sits on the radon scale

Test your home

A county zone can't tell you what's in your house. Neighbors can have very different readings, so testing is the only way to know.

What to do with your result

  1. Below 2 pCi/L: retest every couple of years or after renovations.
  2. 2 to 4 pCi/L: EPA says consider fixing your home.
  3. 4 pCi/L or higher: EPA recommends fixing your home. Confirm with a second test, then contact a certified radon mitigation professional. A typical fix is a sub-slab vent fan system.
  4. On a private well? Consider testing your well water for radon too.
