Q. How often should I check my home for radon?
A. Radon levels vary throughout the year so it’s advisable to test at least once annually. It is best to test in the winter or summer months when your home is closed up and heating or cooling systems are in operation. Test results most accurately measure radon levels in a closed home environment.
For that reason, the Environmental Protection Agency designates January as National Radon Action Month. Also, the state of Colorado has declared January Radon Action Month, and encourages everyone to test their home radon levels.
Even if you have a mitigation system continually operating in your home, you should test every two years to ensure the system is running effectively and performing up to safety standards.
The EPA recommends that you take action to fix your home if your radon level is 4pCi/L (picocuries per liter) or higher. A radon mitigation system operates around the clock. If you have a mitigation system, check your fan monthly to ensure it is still operating. It is likely in the lifetime of the mitigation system that the fan will need to be replaced once or twice.
Radon most commonly enters homes through the basement. You should test for radon in the lowest level room or rooms you are occupying, particularly if you exercise in one of those rooms.
You should not test in rooms containing chemical cleaners, since they will affect test results. If your home test records a high level of radon, a second test will confirm if action is necessary to prevent health consequences.
Radon test kits can be purchased at local hardware stores as well as from Source at 6400 Arapahoe Road, Boulder.
