Test Your Home For Radon

The only way to tell how much radon is in your home is to test for it. By testing your home for radon, you are taking a step toward a healthier indoor environment for you and your family.


Radon is the leading cause of lung cancer among nonsmokers.

What Do My Results Mean?


If the result is less than 4pCi/L- no action is required. It is recommended to retest the house every two years or if renovations or additions are made to building. A long term test can also be done in order to better understand the average year-round radon concentration.


If the result is more than 4pCi/L but less than 8pCi/L, perform an additional Short-Term test. If the average of the two tests is less than 4pCi/L, no further action is required. Retest in 2 years or if any renovations or additions are made to the building. If the average of the 2 tests is 4pCi/L or more the home needs to be mitigated.


If the result is more than 8pCi/L it is recommended that a confirmation Short-Term test is performed.  If the second test shows radon levels equal to or greater than 8pCi/L, mitigation is strongly recommended.  If the second test shows radon levels below 8pCi/L, a Long-Term is recommended to develop a better understand of the annual average radon level in the home.


What You Should Know About Radon Gas Before You Take Drastic Measures


In November of 2007, a national television show featured a family living in a home with elevated levels of radon gas. Radon gas poses a serious health threat at certain levels, but the threat can be alleviated with proven and effective mitigation systems. The producers of the television program, however; decided to take a more dramatic approach to the problem…they detonated the house with explosives.


Unfortunately, the television show left a lasting impression on how to deal with radon gas. Even with this drastic measure, they still had to install a mitigation system in the newly reconstructed home to alleviate the radon problem.


The American Lung Association is taking the opportunity to educate the public on the principles of Radon testing and mitigation by taking humorous look at this action. Please take a look at our fun video response by clicking on the video image at the top of this page.
