Home Buyer's and Seller's Guide to Radon 

​

The EPA recommends:

​​

• If you are buying a home or selling your home, have it tested for radon. 
   

• For a new home, ask if radon-resistant construction features were used and if the home has been tested. 
   

• Fix the home if the radon level is 4 picoCuries per liter (pCi/L) or higher. 
   

• Radon levels less than 4 pCi/L still pose a risk, and in many cases, may be reduced. 
   

• Take steps to prevent device interference when conducting a radon test.

 

The EPA estimates that radon causes thousands of cancer deaths in the U.S. each year.

​

 * Radon is estimated to cause about 21,000 lung cancer deaths per year.

​

The numbers of deaths from other causes are taken from the Centers for Disease Control and Prevention's 1999-2001 National Center for Injury Prevention and Control Report and 2002 National Safety Council Reports.
