There are cracks in the foundation. Nothing structural or that's going to threaten the stability of the Florida home, but they're there. Nooks, crannies and holes through which seeps an invisible threat. Colorless, odorless and undetectable by your average human, it is none the less the second leading cause of lung cancer in the United States.
Even the name sounds ominous, evoking images of radiation and nuclear devastation. Radon gas is created naturally when uranium in the soil decays. The gas then seeps through any access point into a home. Common entry points are cracks in the foundation, poorly sealed pipes, drainage or any other loose point. Once in the home, the gas can collect in certain areas - especially basements and other low-lying, closed areas - and build up over time to dangerous levels. The Environmental Protection Agency of the US Government has set a threshold of 4 pico curies per liter as the safe level. As humans are exposed to the gas over a period of years, it can have a significant and detrimental effect.
How Widespread Is The Problem?
Radon has been found in homes in "all" 50 states. Certain areas are more susceptible than others - Radon Zone Map, but no location is immune. Concentrations of radon-causing materials in the soil can be either natural or man-made. Homes built near historic mining operations may be at higher risk. The only way to tell for sure is to have the home tested.
Testing for radon comes in two forms: active and passive. Active devices constantly measure the levels of radon 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.
How To Remove Radon From Your Home
If high concentrations of radon are found in your Southwest Florida home, you have several options. Since radon is only a problem when it is concentrated in high volume, improving the ventilation in an area is often sufficient to solve the problem. In other cases, it may be necessary to limit the amount of radon getting into the home by sealing or otherwise obstructing the access points. Once again, a professional should be engaged to ensure that the radon is effectively blocked. Typical radon mitigation systems can cost between $3,000 and $5,000, according to the EPA.
Consider Your Options
If you're buying or selling a Southwest Florida home, radon can be a significant issue in some areas. Buyers should be made aware of the radon risk and then determine whether a radon test is desirable. If there is any doubt, the EPA always recommends testing. The cost of the test can be built into the house price. If test results already exist, make sure they are recent (within 2 to 3 years) or that the home has not been significantly renovated since the test was performed. If in doubt, get a new test done. If you're selling a home, having a recent radon test s a great idea. By being proactive, you can assure potential buyers that there is no risk and avoid the issue from the start.
So whether you have an older Southwest Florida home or a new one, radon is a reality. But it is a reality that we can live with. Proper testing and mitigation can eliminate radon as a health threat. For more information, visit the EPA web site on radon at www.epa.gov/radon.
