The mitigation guide explains the system DANR describes and how to find a certified installer, and the cost guide lays out DANR's own install, operating and fan figures.
What the Zone 1 rating means
DANR built its map from radon measurements taken across South Dakota since the late 1980s, compared against geology.1 The zones predict the likelihood of finding certain radon ranges on a short-term test. They don't tell you your own number. DANR says the only way to know a building's radon level is to test it.1
