  2. Radon: Is Your Home Putting Your Health at Risk?

  3. Educational Goals • Increase knowledge of the hazards of radon among Loudoun County residents in Northern Virginia • Increase the number of homes with radon detectors in Loudoun County • Increase the number of homes tested for radon in Loudoun County

  4. What is Radon? Radon is a colorless, tasteless, odorless and radioactive gas produced from the decay of uranium in soil, rock and water (Environmental Protection Agency, 2009). Soil Rock Water

  5. Health Risk • As radon decay it gives off radioactive particles. These particles can damage the cells that line the lungs (National Cancer Institute, 2004). • Long-term exposure and the inhalation of high levels of radon can increase the risk of developing lung cancer (NCI, 2004). • Radon is the second leading cause of lung cancer in the United States (EPA, 2009).

  6. Health Risk Radon is the number one cause of lung cancer among non-smokers (EPA, 2008).

  7. Radon in Homes • The greatest risk of exposure is most likely to occur in the home, particularly in the basement and on the first floor (NCI, 2004). • Radon seeps up through the ground and diffuses into the air (NCI, 2004). • Radon can enter homes through cracks in floors, walls, or foundations, and accumulates indoors (EPA, 2009). • Radon can also enter the home through water providing it is present in well water and building materials such as granite and some concrete products (EPA, 2008).

  8. Radon in Homes • Nearly 1 out of every 15 homes in the United States have elevated radon levels (EPA, 2009). • The quantity of radon is measured in “picocuries per liter of air” or “pCi/L” (EPA, 2009). • The national average indoor radon level is about 1.3 pCi/L (Loudoun County Radon Information, n.d.). • The average indoor radon level in Loudoun County, is 4.7 pCi/L (LCRI, n.d.).

  9. Radon Levels for Loudoun County Homes

  10. The United States Surgeon General Health Advisory The United States Surgeon General issued a Health Advisory warning Americans about the health risk from exposure to radon in indoor air. He urged Americans to test their homes to find out how much radon they are exposed to. He stressed the need to mitigate the problem immediately should the radon level reach 4 pCi/L (EPA, 2008).

  11. National Safety Council The National Safety Council offers short-term and long-term radon test kits that can be purchased over the phone by calling 1-800-557-2366. $15 short-term radon detection coupon $25 long-term radon detection coupon www.downloads.nsc.org/pdf/Coupon2008.pdf

  12. Short-term Testing Short-term tests remain in the home for two to 90 days. The tests commonly used for short-term testing include: • Charcoal canisters • Alpha track • Electret ion chamber • Continuous monitors • Charcoal liquid scintillation

  13. Long-term Testing Long-term testing remain in the home for more than 90 days. The tests commonly used for long-term testing include: • Alpha track • Electret detectors

  14. Recommendations • EPA and CDC recommend taking actions to reduce radon in homes when levels reach 4 pCi/L (EPA, 2009). • EPA also recommend taking actions to reduce exposure when levels are between 2 pCi/L and 4 pCi/L (EPA, 2009). • EPA recommends hiring a qualified radon mitigation contractor to fix your home because reducing radon levels requires technical knowledge and special skills (EPA, 2009).

  15. Radon Reduction Methods • Sealing cracks and openings in the foundation helps to limit the flow of radon into the homes (EPA, 2008). • House/room pressurization creates pressure at the lowest level in the home to prevent radon from entering the rest of the home (EPA, 2008). • Heat recovery ventilator increase ventilation which helps reduce the radon levels in the home (EPA, 2008).

  16. Radon Reduction Methods continued • Natural ventilation temporarily reduce levels by opening windows, doors and vents (EPA, 2008). • Soil suction prevents radon from entering the home by using a pipe or pipes to drawing radon from below the house to the air above the house where it is quickly diluted (EPA, 2008).

  17. Conclusion • Radon levels in Loudoun County homes exceed the national radon indoor level. • Residents of Loudoun County are encouraged to utilize radon detectors and test radon levels in their homes. • Some radon reduction systems and methods can reduce radon in the home by up to 99%. • Reducing radon exposure is especially important for smokers as they have a high risk of developing lung cancer.
