  • What is radon? +

    A. Radon is a colorless, odorless radioactive gas that is found in varying amounts in homes all across the U.S. You can’t see it OR smell it OR taste it. It comes from the natural breakdown and deterioration of uranium deposits buried hundreds of miles below the earth’s surface in soil, rocks and water. Over billions of years these deposits gradually change into radon gas. This comes to the earth’s surface from way down in the earth’s center, and once it comes to the surface it gets into the air we breathe. This gas is free to come up out of the soil and move into the air above. It can enters the average home though cracks or other openings in a home’s foundation. Once it gets into a home, the radon can be trapped and long-term exposure of high radon levels can be hazardous to your health and cause cancer.
  • Q. Why is radon harmful? +

    A. Long Term exposure to elevated levels of Radon Gas can cause lung cancer. In fact, according to the EPA, the U.S. Surgeon General, the American Medical Association and the Kansas and Missouri Health Departments it's the leading cause of lung cancer among non smokers AND the 2nd leading cause of lung cancer in smokers (after cigarette smoking). The particles (radon decay products) created by radon gas as it continues to radioactively change can be breathed into the lungs. These products stick on the walls of the air passages leading to the lungs and on the lung tissue itself.
  • Does radon cause other health effects? +

    A. At the current time it does not appear radon causes other illnesses.
  • Q. What is the EPA’s recommended level of radon? +

    A. EPA recommends that the results of the average short term test with an electronic monitor (48-72 hours) should be less than 4.0 pCi/L. If your testing results are at OR above 4.0 pCi/L then you should mitigate your home.
  • Q. I was told I don’t need to test the home BECAUSE …………..? +

    A. Sometimes a well-meaning seller BUT untrained and naive relative, friend OR real estate agent will try to "pooh-pooh" the radon issue by telling you that only new houses have radon problems or that houses on a crawlspace or those with stone basements are so drafty that they don't have radon problems, etc, etc. These comments are a myth and just plain not true! ANY house can have a radon problem and there is no rhyme or reason to it. This includes new AND old homes alike, drafty OR well-sealed homes, homes on a slab OR on a crawlspace AND homes with or without basements. Two houses on any given block (side-by-side) in the same neighborhood can have totally different indoor radon levels. A national study by the EPA has determined that 1 out of every 15 homes in the U.S. have elevated radon levels. In the Kansas City and surrounding area, it has been established that about 1 in 5 houses have an elevated radon level, and the only way to find out for sure is by testing.
