| 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
over many years, 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.
Estimate
the fraction of houses with average occupant exposures (house
bottom to top) greater than 4 pCi/L for the radon averaged over a
year: divide the
number in the “>10 pCi/L” column by the “Total No.” (of
measurements) column. (Average between basement and
1st floor: 40%) For

The data listed for Zip
Codes crosses county borders.
