Radon is an odorless, colorless, radioactive gas that has been shown to cause lung cancer in humans. Radon gas exists naturally in soil – it is created as various elements of earth decompose. Therefore, it is often found in the basements of homes, entering through fissures, and it can also be present in upper floors. According to the federal Environmental Protection Agency (EPA), exposure to radon gas ranks second to cigarette smoking as a cause for lung cancer.
Increasing number of home-buyers are asking that a home be tested for radon before they agree to purchase. Most sale contracts have a contingency for radon testing. If you are selling your home you may want to have your house tested before you put it on the market. If you have no radon problem, you can provide certification of this to potential buyers. If there is a problem, you can take steps to resolve it, make adjust into pricing and marketing your home. There are professional companies that can inspect your home for the presence of radon. If the gas is found in amounts that exceed guidelines established by the EPA for acceptable levels of radon, there are also companies that can recommend ways to reduce the interior radon concentrations to levels within the EPA’s guidelines.
Radon levels are measured in picocuries, a unit of measurement for radioactive gases. Under EPA guidelines, 4 picocuries of radon per liter of indoor air is the “action level,” meaning something should be done to reduce the presence of radon at the affected location. If you get an initial reading of more than 4 picocuries per liter you should consider having another test done. Experts say radon tests can be inaccurate, so you may want to double-check the levels before you undertake installation of a radon-abatement system.
Mitigating the levels of radon in your home usually involves installing a fan- type apparatus that will suction the gas from under your home’s foundation or elsewhere and carry it outdoors where it can dissipate. Other systems involve forcing fresh air under your house so that the radon will be channeled out, or installing a filtration devices throughout the house.
