Who Can Test?
The Environmental Protection Agency (EPA) encourages all homeowners to test their residences for radon gas concentrations. The National Radon Program Services at Kansas State University (K-state) has radon test kits available for purchase by homeowners for personal use.
Testing is the only way to know if you and your family are at risk from radon. Testing for radon is simple and takes only a few minutes of your time. Radon test kits are placed in the lowest lived-in level of the home and left for a specified period of time. After that time, the kit is sent to the laboratory for analysis.
If you decide to hire a qualified company to do a radon test or a qualified contractor to fix your home, you can find a list with the AARST - National Radon Proficiency Program (AARST-NRPP) and with the National Radon Safety Board (NRSB), or contact your state radon office or public health official. To make sure you are getting a fair price, get estimates from at least two contractors, compare the things they promise to do, as well as the prices, and call their past customers to see if they were satisfied with the work. After work is completed, either buy another do-it-yourself test kit or have a different company test the home to see if radon levels are below 4 pCi/L.
