Radon Measurements for Waukesha County   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.   Waukesha County Measurement Summary - 2006 Numbers of Measurements versus Radon: No. of Measurements Zip Code Total No.      # 4 - 10 pCi/L* # >10 pCi/L Ave. pCi/L High pCi/L 53005 53007 53018 53027 53029 53036 53045 53046 53051 53052 53056 53058 53064 53066 53069 53072 53089 53103 53118 53119 53120 53122 53127 53149 53150 53151 53153 53156 53178 53183 53185 53186 53187 53188 53189 53196 53198   1,666 37 404 201 722 17 565 16 900 3 52 133 9 766 15 483 526 131 195 120 133 405 18 440 478 1,225 59 25 20 145 207 1,774 27 1,185 311 3 1 685 10 129 74 244 5 218 2 354 2 16 38 3 280 6 161 156 48 57 39 42 175 9 166 202 531 22 7 6 43 82 605 9 445 100 2 0   291 3 163 35 234 1 68 3 125 0 36 53 5 149 3 58 194 33 56 43 25 52 2 63 78 133 18 1 0 55 36 224 3 179 48 1 1 6.5 3.5 11.7 7.1 11.1 4.6 5.3 5.1 6.0 5.1 11.0 10.7 5.5 57.5 7.0 4.8 12.4 8.0 8.9 10.8 8.1 5.6 5.6 5.5 6.2 5.4 8.0 3.9 3.2 9.3 6.6 5.3 5.4 6.0 6.0 5.3 13.4   190.0 12.4 80.2 56.6 180.0 23.2 75.1 12.3 76.7 7.3 41.6 46.9 14.6 170.0 20.4 28.4 140.0 53.4 44.6 57.4 55.1 48.8 18.1 35.2 64.0 41.8 28.4 19.7 9.1 34.4 110.0 86.6 24.6 90.0 62.4 7.0 13.4 Zip Code      No. of Measurements      Ave. pCi/L      High pCi/L Total No.     # 4 - 10 pCi/L*     # >10 pCi/L * pCi/L: picoCuries per Liter, a measure of radon concentration 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. The data listed for Zip Codes crosses county borders. Information provided by the Wisconsin Department of Health and Family Services.
