How widespread is the problem? Radon Gas has been found in homes in all 50 states. Certain areas are more susceptible than others (http://www.epa.gov/radon/zonemap.html), but no location is immune. Concentrations of radon causing materials in the soil can be either natural or manmade. Homes built near historic mining operations may be at higher risk. The only way to tell for sure is to have a home tested. We have done thousands of Radon Tests in Sandy and surrounding counties for years. We find Radon Gas all the time. Testing for radon comes in two forms: active and passive. Active Devises (which is what we utilize) constantly measure the levels of Radon Gas in a portion of the home and display those results. Passive devices collect samples over a period of time and then are taken away and analyzed. Either method can help you determine your level of risk. Do-it-yourself kits are available from a number of outlets, normally with passive devices. Over a period of days, the device is left in the lowest level of the home which is normally occupied. This eliminates crawl spaces under the house, but includes finished or unfinished basements. Then the results are analyzed by a professional. The other option is to engage a qualified professional to conduct the tests properly.
If high concentrations of radon are found in your home, installation of a Radon Gas Mitigation system is likely. These systems generally start at 2,500 dollars. It was worth it for me to have a Radon Gas Mitigation system installed in my own home for the safety of my family. My own house had already had a long term passive test performed, prior to me purchasing the home, which indicated that the levels were within a safe range. AFter retesting my home, the levels were consistently higher. I had a Radon Mitigation system installed.
