Questions about radon testing
How many radon testers are in Colorado?

What kinds of businesses test for radon in Colorado?
Of the 56 businesses listed: 42 radon companies that test and fix radon; 9 home inspectors; 3 other businesses that test for radon; 2 radon testing companies. Radon specialists often also fix high levels; home inspectors usually test during a home sale.
How do I choose a radon tester?
The EPA suggests your state radon program as the place to find qualified professionals, and says states list only providers credentialed by a state license or by one of the two national programs, the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). Ask a tester which credential they hold. Source.
What radon level needs fixing?
The EPA says to fix your home if the radon level is 4 pCi/L or more, and to consider fixing it between 2 and 4 pCi/L. Source.
Should I get a short-term or long-term radon test?
A short-term test takes a few days and is a quick way to screen a home. A long-term test runs at least 91 days and shows your average level over the year. A high short-term result is usually followed by a second test before deciding to fix. Source.
Can I test for radon myself?
Yes. The EPA notes that test kits are sold online and in home improvement stores, and that some states offer free or discounted kits. A professional test is common when buying or selling a home. Source.
