Radon

About Radon

Radon is an odorless, colorless gas that is found naturally in the environment. Radon can enter homes through cracks in the walls and floors, construction joints, and gaps around pipes and in floor joints. 

Long-term exposure to radon is known to increase risk for lung cancer, so it is vital to screen for radon exposure in the home. If radon is found at high levels, mitigation can decrease your exposure and your risk for lung cancer.

Where to get a Test Kit

Annual Radon Testing Program 

The Middletown Health Department and CT Department of Public Health distribute radon test kit yearly to Middletown homeowners for testing. A limited number of test kits are available each winter. To inquire about the radon testing program, call the Middletown Community Health Educator at (860) 638-4962. 

Interpreting Results

Radon levels are measured in pCi/L. Radon levels below 2 pCi/L do not require any action, though re-testing after renovations is recommended. 

If testing reveals radon levels over 2.0 pCi/L, CT Department of Public Health recommends re-testing within a month of the first test. After the second test result returns, the homeowner should take the average of the two results. 

If the average result is over 4 pCi/L, radon levels are considered "high," and mitigation is recommended. If the average result is less than 4 pCi/L, regular testing is recommended. Mitigation may also be considered at this level.
