HARRISON COUNTY, Ind. — In 2018, we sent open records requests to districts in our area. After we started asking questions the district started testing.

In 2019, we checked with the district again to see if it is doing anything differently. Superintendent Steve Morris said in an email, "last year, we tested informally with devices from the local health department.  Our highest reading was 3.7 (ironically, in my office).  None of our readings required mitigation.  We have plans to test informally again this year but haven't done so yet. Prior to last year, no, we hadn't done any testing for radon.  It is now something we have on our radar to check annually."

INFORMATION FROM THE EXPERTS:

Indiana schools are not required to test for radon but being exposed to the average levels in Harrison County (4.0 pCi/L) is equivalent to smoking a half a pack of cigarettes a day, according to the EPA. 

Approximately 21,000 Americans die annually from radon-induced lung cancer, including people who have quit smoking or never smoked.

The EPA recommended action level is at 4 pCi/L, while the World Health Organization recommends action at 2.7 pCi/L. Both organizations are clear, no level of radon exposure is safe, especially long-term. 

Changes in the building and environment could cause changes in radon exposure levels, therefore the EPA recommends retesting every building at least every other year to make sure levels do not reach dangerous levels.

The only way to know if levels of radon gas are dangerous is to test and retest.
