| The
numbers of results at various radon levels, tabulated below, are from
measurements in basements, up to a week in duration, while windows are
kept closed. Because there is
less radon upstairs and less when windows are open, this table represents
neither average resident exposures nor their lung cancer risks from radon.
The data were obtained largely from
companies that sell radon detectors to the public, and are only a fraction
of all radon measurements that have been made in
Wisconsin.
For estimating the fraction of houses
with average occupant exposures greater than 4 pCi/L for the radon
averaged over a year on the main floor: divide the number in the “>10
pCi/L” column by the number in the “Total No.” (of measurements)
column. For more information
on that relationship, click
here.
The data listed for Zip
Codes crosses county borders.
