3. Where Does Radon Come From? The natural radioactive decay of Uranium and other heavy elements (such as Vanadium) in the soil Radon is found everywhere in the United States You get exposed to radon daily, but in concentrations that are well below dangerous (but not risk free) levels – except at home, work, or in any building

4. How does radon get in? Through cracks in the foundation Around plumbing and electrical lines Through water when wells contain high levels of radon gas US EPA http://en.wikipedia.org/wiki/Basement

5. What level of radon is safe? Radon is measured in picoCurries per liter of air (pCi/L) The level or radon in outside air is 0.4 pCi/L on average The average indoor level is 1.3 pCiL Mitigation should occur when levels exceed 2 pCi/L and MUST occur when over 4 pCi/L THERE IS NO “SAFE” LEVEL in the home or workplace.

6. How do I measure radon levels? There are a two test types, short term and long term Short term tests are less definitive and run from a few days to a few months. Long term tests are more definitive and take 6 months or more Since any level of radon be dangerous, either test is effective. Wikimedia Foundation

9. What should I know about radon? Mitigation should occur when levels exceed 2 pCi/L THERE IS NO “SAFE” LEVEL in the home or workplace. Smoking plus radon levels over 2 pCi/L magnify your risk of cancer several fold (4 times greater than dying from poison) + = Ottone, 2008 Wikimedia Foundation
