January is National Radon Action Month. Radon is an odorless, colorless and tasteless radioactive gas that naturally gets released when uranium decays, and is found in rock, soil and water. It is the second-leading cause of lung cancer after smoking. There are an estimated 21,000 radon-related deaths each year in the U.S. The EPA recommends that homes with levels at or above 4 pCi/L be mitigated. Frederick County has some of the highest levels in the state. I have seen levels as high as 500 pCi/L in Mount Airy, New Market/Linganore 250 pCi/L, Monrovia 250 pCi/L, Spring Ridge 100 pCi/L, Urbana 200 pCi/L, Adamstown 200 pCi/L, Middletown 50–100 pCi/L and Thurmont 100-150 pCi/L. Even with a passive system, homeowners should test. Test kits can be purchased at Lowe’s for less than $20. This simple test could save your life.
