The Missouri Department of Health and Senior Services provides radon information for the public, including data on radon testing in public schools. Most of the state’s counties are in Zone 2, the USEPA classification, where predicted average indoor radon screening levels would be from 2 to 4 pCi/L. Eleven counties are in Zone 1, where predicted average indoor radon screening levels greater than 4 pCi/L, the recommended USEPA action level.
Interactive mapping of radon testing in public schools allows filtering by county and school name in order to zoom to results or statewide data can be viewed of all counties and districts. Selections include public schools and districts tested. Map background may be chosen.https://ogi.oa.mo.gov/DHSS/EPHT_radonSchool/index.html
