Radon Testing in Connecticut — FAQ
How often should I test for radon in Connecticut?
The EPA recommends testing every two years in Connecticut. Always test when moving into a new home, after renovations that affect lower levels, and after installing a mitigation system.
What is the EPA action level for radon?
The EPA recommends taking action to reduce radon if indoor levels reach 4 pCi/L or higher. Even levels between 2–4 pCi/L present risk, and mitigation is recommended where feasible.
Do I need a certified radon tester in Connecticut?
For real estate transactions, most states require a certified tester. Look for NRPP or AARST-NRPP certification. Connecticut may also have its own state program — check your state radon office for specific requirements.
