Radon Concentration Statistics for the State of Ohio
The following statistics have been calculated for radon measurements in all zip code areas and counties. Click on any statistical parameter in the table below to get information on how it is computed.
|Geometric Mean||First Quartile|
In computing these statistics, every radon measurement in a county or zip code area was used without regard for building, room or detector type, or season.

Tip: For comparing radon concentrations in various geographical areas, the geometric mean is the most appropriate value. In addition, note that the maximum concentration is greater than 4 pCi/l in most areas, thus confirming the need to test all homes and schools
