Radon Gas – Think you’re not at risk? Think again!

Radon Gas – Think you’re not at risk? Think again! – Part I

There are cracks in the foundation. Nothing structural. Nothing thats going to threaten the stability of the home, but theyre 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.

radon gas property guidingRadon gas – even the name sounds ominous, evoking images of radiation and nuclear devastation is created 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 (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 man-made. Homes built near historic mining operations may be at higher risk. The only way to tell for sure is to have a home tested.

Testing for radon comes in two forms: active and passive. Active devises 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. The EPA web site (http://www.epa.gov/radon/manufact.htm) provides information on finding an appropriate resources and testing devices.
