What is Radon? Radon is a colorless, tasteless, odorless, and radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes. Because radon comes naturally from the earth, people are always exposed to it.

Radon Health Risks: Radon is the leading cause of cancer among non-smokers. Overall, radon is the second leading cause of lung cancer.

Radon Mitigation: Testing is the only way to find out if your home has elevated radon levels. The DPH Radon Program recommends that Connecticut residents throughout the state test the air in their homes for radon. If your house has elevated levels of radon, you should choose a qualified radon mitigation (reduction) contractor to take steps to reduce the levels to below 4 pCi/L, the EPA Action level for Radon. Qualified radon contractors have attended specialized courses and are registered through the CT Department of Consumer Protection. A mitigation contractor takes steps including installing ventilation systems, sealing entry routes for radon gas and installing sub-slab depressurization systems to reduce radon levels. The approximate cost of a radon mitigation system in Connecticut is $1,200. Visit the CT DPH website for a list of qualified radon mitigation professionals.
