Radon is the #1 Cause of lung cancer after smoking, world-wide. Radon is a colorless, tasteless and odorless gas that is present at some level in almost all 48 U.S. states. It is found in higher concentrations in some areas more than others, though in Tennessee, it is nearly everywhere. Tennessee average readings are above the national average.
It is recommended that every home changing hands in a real estate transaction be tested as there is no way to know what the level of radon is in a home or building if it is not specifically tested for it.
There is a fast test, 48 to 72 hours, to help real estate transactions move along and fit into the inspection window. Should levels be found above the EPA standard for mitigation, a longer test is required to revalidate the readings as radon levels can vary day to day depending on the weather and other mechanical influences going on in the building. A longer test may produce a different average.
What happens if the home or building tests above the EPA standard for mitigation? There is a relatively straight forward method to “pull” the radon gas from under the home and moving it into the atmosphere above the home. This involves creating negative air pressure under and around the home’s foundation. It is relatively inexpensive and can be installed quickly. The home should be re-tested after a short settling in period, of the newly installed system, and then re-tested annually to ensure the system is working as intended.
So, Radon does not have to be the big scary elephant in the room. With test data, the facts, the presence of radon can be mitigated, and life can go on like it was or is not there.
