Heads up, Boston: A helicopter will be flying around the city at altitudes as low as 150 feet this week, but officials say there’s no cause for concern.
The National Nuclear Security Administration announced in a statement that from Tuesday through Friday, a low-flying helicopter will be measuring “naturally occurring background radiation” over an area covering 13 square miles.
The helicopter, equipped with radiation-sensing technology, will fly in a grid pattern at about 80 miles per hour. The flights will only happen during daylight hours.
“The measurement of naturally occurring radiation to establish baseline levels is a normal part of security and emergency preparedness,” the statement read.
