Virginia Indoor Radon Program

Exposure to indoor radon, a colorless, odorless radioactive gas, is thought to be the second leading cause of lung cancer, and the leading cause of lung cancer among people who have never smoked.  Exposure to radon may contribute to 21,000 cases of lung cancer each year in the United States, including almost 700 cases per year in Virginia.

The Environmental Protection Agency (EPA) classifies radon risk areas as Zones 1, 2, or 3.  Virginia has 46 counties and 15 cities that are classified as Zone 1 (high risk), and 24 counties and 8 cities classified as Zone 2 (moderate risk).  Click here for a VA risk map.  Testing your home, workplace or other normally occupied area is the only way to know for sure if an indoor radon problem exists.  For more details about radon testing and mitigation, see this page:  Radon Testing & Mitigation Radon informational brochures and documents are available here: Radon Publications.

VDH is making a limited supply of short-term, do-it-yourself radon test kits available for only a $3 shipping fee.  NOTE: This offer is only available between the dates of September 1 and May 31. To order your $3 test kit click on this link.

Five Things to Remember When Interpreting Epidemiologic Data

We know that the number of cases we have on record is an underrepresentation of the true burden for several reasons. Some underrepresentation is because testing for SARS-CoV-2 might not be available for the infected person… Another factor is that not everyone will need to see a doctor for COVID-19. The World Health Organization (WHO) published a very detailed report about the outbreak of COVID-19 in China and found that 80% of cases were mild or moderate. Since then, there have been studies that have identified infections in people who never develop symptoms. If someone gets infected and recovers on their own, then public health may never find out about the case.
