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.
