Wisconsin Data on Radon Presented in On-line Mapping Tool

by Margaret Henderson

The Wisconsin Department of Health Services provides radon information at https://www.dhs.wisconsin.gov/radon/index.htm. Data on radon tests are presented on-line so that residents can find out where radon test results have been the highest. An interactive map, “Wisconsin Indoor Radon Levels,” features test results give in average radon levels and the percentage of test results greater than or equal to 4 pCi/L, the recommended USEPA action level. http://wi-dhs.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=a0f619747b5e4e72bce960619e6663e8

The clickable map allows the user to identify areas by color-coding. Test results are given for at particular area. The results show for Mosinee indicate that out of 942 homes tested, 62.5% exceeded 4 pCi/L. The average result was 13.94 pCi/L and the maximum was 351.30 pCi/L. A contact is given along with the results so that the user may seek further information. In Wisconsin, the average radon level (lowest lived-in floor) is around 1.8 pCi/L. In basements, about 25% of the homes have radon levels > 4pCi/L and in some areas of the state, more than half of the home basements have radon concentrations > 4pCi/L.
