What is Radon?
Radon is a naturally occurring radioactive gas that is colorless, odorless , and tasteless. It is formed by the natural breakdown of uranium in rock, soil and water. Radon gas moves up through the soil and can be drawn into our homes by slight pressure differences. Once inside, radon can become trapped and build up to unsafe levels.
What is the Concern?
The U.S. Environmental Protection Agency (US EPA) and the Surgeon General’s Office have estimated that as many as 20,000 lung cancer deaths are caused each year by radon. Radon is the second leading cause of lung cancer after cigarette smoking and the number one cause of lung cancer in non-smokers.
What are the Levels of Radon?
The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels. While this goal is not yet technologically achievable in all cases, most homes today can be reduced to 2 pCi/L or below. The current standard or action level is 4 pCi/L. Even if your test result is below 4 pCi/L, you may want to test again sometime in the future.
