What is Radon?

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rocks and water. Air pressure inside your home is lower than pressure in the soil around your home’s foundation. Because of this difference in pressure, your home acts like a vacuum, drawing radon in through foundation cracks and other openings Radon may also be present in well water and can be released into the air in your home when water is used for showering and other household uses.


Radon is a Cancer-Causing, Radioactive Gas

 You cannot see, smell or taste radon but it may be a problem in your home. There are no immediate symptoms that will alert you. It typically takes years of exposure before any health problems surface. Testing is the only way to know your home’s radon levels. Radon is estimated to cause many thousands of lung cancer deaths each year. In fact, the EPA and the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.


What do your Radon Test Results mean?

 Any radon exposure has some risks of causing cancer. The lower the radon level in your home, the lower your families risk of lung cancer.

The radon testing results is important information about your home's radon level. NJDEP requires radon measurement technicians to follow a specific testing protocol. 

The amount of radon in the air is measured in “picocuries of radon per liter of air”, or “pCi/L.” Sometimes test results are expressed in Working Levels, “WL”. A level of 0.02 is equal to 4 pCi/L, in a typical home. The EPA recommends fixing your home if the tests results show radon levels of 4 pCi/L or Higher.

If you do the test yourself, you should carefully follow the testing protocol for your area or EPA's Radon Testing Checklist.


How can I fix my home’s High Radon Levels?

If you find that you have high radon levels, there are ways to fix it through radon mitigation. Even very high levels can be reduced to acceptable levels. The EPA recommends that you have a state licensed radon mitigation contractor fix your home because lowering high levels requires specific technical knowledge and special skills. A list of NJDEP licensed mitigation contractor's can be found on their website.
