What are closed-house conditions?
Closed-house conditions mean keeping all windows and outside doors closed except for normal entry and exit. Do not operate fans or machines that bring in outside air during the test. You should operate your home's heating and cooling systems normally. For tests under one week, only use air-conditioning units that recirculate interior air. Brief periods of open windows can affect short-term test results, so avoid them entirely.
Where should the test kit go?
Place the radon test device in the lowest level of the home that is regularly used. This is often where radon levels are highest. Do not place the kit in a kitchen or bathroom. These areas have humidity and airflow patterns that can skew the results. Ensuring proper placement helps get a valid reading for your specific living space.
How long does the test take?
The EPA recommends a minimum test duration of 48 hours for short-term radon tests. Some devices may require longer exposure times, so check the specific kit instructions. You must close windows and outside doors at least 12 hours before beginning the test. Maintaining these conditions for the entire period is crucial for an accurate measurement of radon gas levels.
Who is qualified to test?
EPA recommends using a state-certified or nationally certified radon measurement professional for home testing. Kentucky-certified contractors with NRPP or NRSB credentials are qualified to perform these tests. You can verify certification through the state program list. Hiring a pro ensures the test is placed correctly and interpreted accurately. They can also advise on mitigation if levels are high.
What affects radon risk in KY?
Radon risk varies by county, and all 120 Kentucky counties are mapped into EPA radon zones. The Department for Public Health’s Radon Program handles state information. Even if your neighbor's home is low, yours could be high. Testing is the only way to know your specific home's radon level. Do not rely on general zone maps for your specific address.
