Indiana Requires Certification of Radon Testers and Mitigators

by Margaret Henderson

The Indiana Radon Program has the responsibility of licensing radon testers and mitigators in the State of Indiana, and providing the public of Indiana information about radon and its effects. http://www.in.gov/isdh/24346.htm

Indiana counties are designed as either Zone 1 or 2 (USPEA radon zones). Zone 1 counties are predicted to have average indoor radon screening levels greater than 4 pCi/L. Zone 2 counties are predicted to have average indoor radon screening levels from 2 to 4 pCi/L. As indicated by test results from the year 2013, in Zone 1, the percent of Indiana homes exceeding 4 pCi/L in Zone 1 was 36%. In Zone 2, 35% homes exceeded 4 pCi/L, indicating that zone designations are only predictors and actual testing is necessary to determine the radon concentrations in any home. In Indiana, the highest twelve test results in 2014 were greater than 70 pCi/L of radon. Between 2007 and 2014, the number of homes tested in Indiana was 59,451.

With test results indicating a considerable number of homes in Indiana have elevated radon levels, the importance of testing and mitigation was recognized by the Indiana legislature. Indiana statutes require establishing and operating certification programs for person who test for or abate levels of radon gas and designates authority to collect fees for certification, along with other specifications. Tester and mitigation application fees are $100 each. The Radon Program provides guidance on becoming certified and also allows the public a search feature to search and verify licensed testers and mitigators on-line http://www.in.gov/pla/3119.htm Lists of 254 testers and 51 mitigators who are certified are provided on-line, updated as of July 2017.
