National Nuclear Security Administration
NNSA to Conduct Aerial Radiation Assessment Survey over Arlington, Virginia, Area

July 21, 2017

The U.S. Department of Energy's National Nuclear Security Administration's (DOE/NNSA) will conduct a low-altitude helicopter flight over portions of the Arlington, Va., area July 22 to measure naturally occurring background radiation.

Officials from NNSA announced that the radiation assessment will cover approximately three square miles. A twin-engine Bell 412 helicopter, operated by the Remote Sensing Laboratory Aerial Measuring System from Joint Base Andrews, will be equipped with radiation sensing technology.

The helicopter will fly in a grid pattern over the area at 150 feet (or higher) above the ground surface, at a speed of approximately 80 miles per hour. Flyovers will occur only during daylight hours and are estimated to take about three hours to complete.

The measurement of naturally occurring radiation to establish baseline levels is a normal part of security and emergency preparedness. NNSA is making the public aware of the upcoming flights so that citizens who see the low-flying aircraft are not alarmed.
