Radon is the number one cause of lung cancer among non-smokers, according to the Environmental Protection Agency (EPA). Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 20,000 lung cancer deaths every year.
Radon is a radioactive gas found in nature, and has no color, odor, or taste. It comes from the decay of uranium atoms. Buildings capture radon leaking up from the ground on which they are built. In Aspen, over 1/2 of the homes that have tested have radon levels in excess of the EPA recommended action level of 4 picocuries (pCi) of radon per liter of air.
The only way to know if your home has high radon is to test your home with a radon test kit. Winter is the best time to test for radon as your windows and doors are closed. Currently, the Aspen Environmental Health & Sustainability Department has free radon test kits available for Aspen residents. If you are outside Aspen city limits then contact your local Environmental Health Department as they might have radon test kits for their jurisdiction.
If your first radon test result is at or above the EPA action level of 4pCi/L and is considered high, then your next step is to retest. EPA recommends for radon results between 4-8 pCi/L you retest using a long term test kit. If your result is above 8 pCi/L then retest in the same location with another short term test kits. Currently, the City of Aspen has both short and long term radon test kits available to Aspen residents.
If you live outside the Roaring Fork Valley, or your jurisdiction has run out of free kits then you can purchase a
do it yourself radon test kit
with the National Safety Council.
The EPA set the recommended action level for radon at 4.0
pCi/L so that if your home is greater than 4 pCi/L, it is recommended you
take action to reduce the radon in your home. Lowering high radon levels requires
technical knowledge and special skills. The right system will depend on a
number of factors including the design of your home. An experienced radon
mitigation professional is your best resource to assess and advise you of your
The City of Aspen recommends that you only use certified
radon mitigation contractors to do the work on your building. A certified
contractor will have their NRPP certification with them as proof. The
City recommends getting more than one bid. Below are some certified
contractors that are known to regularly do work in the Roaring Fork Valley.
This list is not inclusive of all companies or individuals qualified to do
radon mitigation in single family homes. Also, if you would like to try
other certified contractors you can go to the State’s website which has an
up-to-date list of NRPP certified contractors.
Contractors on the City and Colorado lists have taken a
nationally-certified training course, passed the national certification exam,
and retain their national certification through continuing education. The cost
to mitigate radon depends on how your home was built and the extent of the
radon problem. In general, costs can range from approximately $1,500 to $2,500
for a medium size home. The City of Aspen can also provide assistance for Aspen
residents to ensure that successful mitigation is done.
Please note that the City of Aspen does not specifically endorse any of the companies on this list, but they are provided for your reference.
