“Indoor Radon is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country. It’s important to know that this threat is completely preventable. Radon can be detected with a simple test and fixed through well-established venting techniques.”


Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. It can be found all over the U.S. and can get into any type of building—homes, offices, and schools and result in a high indoor radon level. You and your family are most likely to get your greatest exposure at home. Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels.

The amount of radon in the air is measured in “picocuries per liter of air,” or “pCi/L.” The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels; about 0.4 pCi/L of radon is normally found in the outside air. EPA recommends fixing your home if the results of one long term test or the average of two short term tests show radon levels of 4 pCi/L or higher. You also may want to consider fixing if the level is between 2 and 4 pCi/L.

Radon gas is odorless and invisible and the only way to know if your home or building has a radon problem is to test for it.


Help is available to fix a radon problem. Most homes can be fixed for about the same cost as other common home repairs. With today’s technology, radon levels in most homes can be reduced to 2 pCi/L or below. Some radon test / reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels. TES’ radon testing & mitigation specialists follow industry consensus standards, such as applicable state regulations and the American Society for Testing and Materials, ASTM, Standard Practice for Installing Radon Mitigation Systems in Existing Low-Rise Residential Buildings, E2121.
