The Minnesota Department of Health, through continued data collection and analysis, found that radon levels are higher than EPA radon risk potential predicted. This information has added to the understanding of radon risk in Minnesota and is used by the public and officials in addressing excess exposure to radon.
MDH Tracking partnered with the MDH Indoor Air Quality Unit to analyze radon test results from eight private radon labs in Minnesota and develop key radon data measures to highlight differences in radon testing and radon levels across Minnesota counties. This effort resulted in additional data more amenable to analysis. The number of radon tests conducted in each county was then adjusted for population size in order to compare testing rates by county.
Results showed that:
o 72% of counties have average radon levels that exceed ≥4 pCi/L and
o 2 in 5 Minnesota buildings tested statewide have radon levels that pose a significant health risk.
The MN Data Access portal now provides county-level, seasonal data and other information. Interactive maps and charts show:
o Nine radon measures per county
o Minnesota radon levels compared to national levels
o Annual number of tests conducted
o Number of counties within the EPA radon level categories
o Radon level seasonal variation.
