RADON ASSESSMENT AT NAVAL SUPPORT ACTIVITY ANNAPOLIS
A previous radon survey occurred at NSA Annapolis in 2017 with additional radon retesting occurring periodically afterwards. Starting June 2025, a one-year radon assessment will be conducted to determine indoor radon gas levels at selected locations within NSA Annapolis. This survey is being conducted as a routine task here at NSAA as well as other Naval Installations service wide and at other facilities of the Armed Forces.
The assessment is not being conducted because of a known concern, but rather as a proactive step to ensure our service members and employees live and work in a healthy environment.
If elevated levels of radon are found, steps will be taken to formulate a plan for corrective action.
We ask for cooperation from everyone in making sure the test devices are not disturbed throughout the required full year they will be in place.

NSAA Radon Fact Sheet
What is Radon?
Radon is a naturally occurring gas that comes from the breakdown of minerals found in certain geologies. It is not because of any man-made pollution, such as landfills or illegal dumping, but rather natural occurring radon.
What does Radon do to me?
Exposure to elevated levels of radon over extended periods of time can increase the potential for lung cancer. This is why the U.S. Navy is taking steps to identify potential concerns.
Where is Radon a Concern?
Radon can be present in any structure that is constructed over radon producing soils or rocks. Your personal residence can be of particular concern, especially with the amount of time that you and your family members spend there. That is why the U.S. EPA as well as many state agencies recommends that all homeowners and schools test for radon.
EPA Map of Radon Zones (Maryland)
The map below was developed by the U.S. Geological Survey and the U.S. EPA, and depicts counties with high radon potential in red (≥4 pCi/L), moderate radon potential in orange (>2 - <4 pCi/L), and low radon potential in yellow (<2 pCi/L). However, these are only predicted averages based on available historic radon testing data primarily from home testing and soil/geology data. Homes with elevated levels of radon have been found in all three zones. For this reason, it is highly recommended that in addition to this survey, you test your own home for radon.

Key Things to Remember about the Survey:
- The devices will be attached to walls, bookcases.
- They will be in place for one year.
- Because radon comes from the ground, only lower portions of a selected building will be tested.
- They pose no health risk and do not contain electronic recording instrumentation of any kind.
- Please do not disturb the devices.
