A study by two University of Iowa researchers confirms a link between lung cancer and radon. The U-of-I analysis of seven different residential radon studies showed an 11 to 21 percent increase in lung cancer risk for radon concentrations that are just below the U-S E-P-A’s action level for radon. University of Iowa professor R. William Field says the study agrees with a large-scale study of radon exposure done in Europe. Radon gas can seep into the home from the decay of naturally occurring uranium in the earth’s soil. Iowa AIR Coalition co-ordinator Cindy Shubatt says the best test for radon costs $5 and needs to sit out for three to seven days. The test is available at most hardware stores or you can call the Iowa Department of Public Health at 1-800-383-5992.
