Press Release
Apr 16, 2014

BOSTON – The National Nuclear Security Administration (NNSA) will measure naturally occurring background radiation over areas west of downtown Boston, Mass., April 17-20, 2014. A helicopter may be seen flying at low altitudes while the radiation assessment is conducted and will cover approximately 10 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 areas 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.

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.
