Invisible, Odor-free and Potentially Hazardous - 3/8/2015
Most people's first introduction to Radon is during the inspections of a home. It can be as much a surprise to a seller as it is a buyer. Radon is an invisible and odor-free, cancer-causing radioactive gas.
Radon can get into a home through cracks in solid floors, construction joints, cracks in walls, gaps in suspended floors, gaps around service pipes, cavities inside walls and even the water supply.
It is estimated that one out of every fifteen homes in the United States has elevated radon levels. The EPA recommends that you test your home which is the only way to find out if you and your family are at risk. If the level found is 4 picocuries per liter or higher, the EPA suggests that you make repairs or install a radon reduction system. Even lower levels can have health risks.
The EPA's interactive map is available to find state and county information but still recommends that all homes should test for radon. More information can be found from the EPA in A Citizen's Guide to Radon.
Test kits are inexpensive and can be purchased at stores like Lowe's or Home Depot if you choose to do it yourself. If levels indicate a high enough level, you can contact a qualified radon service professional for another test or to mitigate your home. You can get information on identifying these professionals at www.nrpp.info and www.nrsb.org.
