Radon may now be the leading cause of lung cancer in the United States; outing smoking in the last couple years. Radon comes from the natural breakdown of uranium in soil and is always in the air we breathe. It can be found all over the U.S. and can become concentrated in any building. The EPA recommends regular testing of all buildings including homes, churches, and schools. However, you are most likely to get your greatest exposure at home where you spend most of your time.
Typically a short-term, 48 hour, measurement is taken but longer measurements are available. Immediate results are available and if the test shows a higher than acceptable limit, guidelines set forth by the EPA are available .
