Highlights from the Connecticut Department of Health Radon Program

Contributed by Allison Perry Sullivan

In FY 2017, the Connecticut Department of Health (CTDPH) Radon Program partnered with 22 local health departments across the state. As part of the partnership more than 1800 radon test kits were distributed to state residents. The Radon Program tracked the return rates of the kits and the test results. The overall return rate of radon test kits for all health departments participating in the partnership was 53%. Return rates ranged from 4% to 97% among local health partners. A total of 112 Connecticut homes were found to be at or above the USEPA recommended action level of 4 pCi/L.

Connecticut law requires that all public schools evaluate radon as part of an indoor air quality inspection program. State health officials estimate nearly one in seven public school buildings in the state have had at least one classroom with an elevated radon level between 1991 and 2017. In 48% of school buildings where elevated radon levels were found mitigation systems have been installed by a qualified radon mitigation professional. In FY 2017, 13 initial schools were measured for radon and 273 schools were re-evaluated. A total of 1804 school classrooms were tested. Elevated radon levels were detected in 13 classrooms in 11 schools. In FY 2017, mitigation work was documented in three schools. A total of eight classrooms were mitigated at these locations.

As of October 1, 2016, the Connecticut State Building Code adopted Radon Resistant New Construction (RRNC) language in Appendix F for passive radon gas controls in one and two family homes and townhouses. On February 15, 2018, Doug Kladder of CERTI, Inc., was hired to conduct a 2.5 hour RRNC training specifically designed for an audience of approximately 30 Connecticut local building officials. A video was completed to share on our CT Train website for any local building officials not in attendance to view.
