What do radon test results in Lexington show?
Kentucky's most detailed indoor radon potential map was built using over 70,000 home test kit results statewide. This map integrates geological data with these test results. However, the Kentucky Geological Survey (KGS) emphasizes that this map shows potential based on bedrock, not actual measured values in homes. Actual in-home radon levels can be higher or lower than the map suggests and may fluctuate with the seasons. Therefore, home radon testing is essential to determine the specific radon level in your Lexington or Fayette County residence.

How does the EPA view radon in Kentucky?
The EPA has found elevated radon levels in all three of its designated radon zones across Kentucky. Because of this, the EPA advises that all homes should be tested for radon, irrespective of their zone designation. The EPA's Kentucky radon zone map is not intended to dictate whether a home in a specific zone needs testing. Instead, it was created to help organizations focus resources and implement radon-resistant building codes. For a more precise understanding of radon potential in your specific Lexington area, the EPA recommends supplementing the county map with local data.
Is radon testing common in Lexington?
Only about 13 out of every 10,000 homes in Kentucky are tested for radon annually. This low testing rate means many homeowners may be unaware of potential radon risks within their homes. The Kentucky Radon Program offers free radon test kits to residents, and many local health departments in counties like Fayette also provide them. Yearlong test kits are particularly recommended for those living in areas with karst geology, which includes features like sinkholes, underground streams, and fissured rock common in parts of Kentucky.
What radon level requires mitigation?
The Environmental Protection Agency (EPA) recommends radon mitigation if a home's test results show a level of 4 picocuries per liter (pCi/L) or higher. Similarly, Kentucky Housing Corporation policy mandates radon mitigation if testing indicates levels at or above 4.0 pCi/L. Mitigation must continue until radon levels are successfully reduced to below this 4.0 pCi/L threshold. This guideline ensures that homes are made safer for occupants by reducing exposure to this radioactive gas.
