Basic Radon Information
- Radon is a colorless, odorless radioactive gas. Radon Information Sheet (PDF)
- According to the EPA, radon is the number one cause of lung cancer among non-smokers.
- The only way to know if your home has high radon is to test.
Understanding Your Test Results
If your first radon test result is at or above the Environmental Protection Agency's (EPA) action level of 4 picocuries of radon per liter of air (pCi/L), then your next step is to retest:
- For results between 4 and 8 pCi/L, retest with a long term test kit.
- For results above 8 pCi/L, retest in the same location with another short term test kit or kits.
- The City of Aspen has both short and long term radon test kits available to Aspen residents.
- Over 1/2 of the homes tested in Aspen have levels in excess of the EPA recommended action level of 4 pCi/L.
- High levels of radon (4 pCi/L or above) can be reduced through mitigation.
If your test results are greater than 4 pCi/L, the EPA recommends mitigation.
- Lowering high radon levels requires technical knowledge and special skills.
- The City recommends that you use a certified radon mitigation contractor to ensure that the the correct system is installed for your building.
- Mitigation costs can vary depending on the construction and type of home but generally costs range from approximately $1,500 to $2,500 for a medium size home.
- The City can provide assistance for Aspen residents to ensure that successful mitigation is done.
- A list of local certified radon mitigators is provided for your reference though the City does not specifically endorse individual companies.
