|About two in five homes have dangerous levels of radon — every home should be tested. Radon is the leading environmental cause of cancer deaths in the United States and the leading cause of lung cancer among non-smokers. More than 21,000 lung cancer deaths are attributed to radon each year in the U.S.|
To help residents get a more accurate picture of radon, the Minnesota Department of Health launched a radon data portal. The portal includes interactive maps that describe radon levels and disparities in testing and mitigation rates. Learn more about radon.
