Washington, D.C. – The U.S. Department of Energy’s National Nuclear Security Administration (DOE/NNSA) will conduct low-altitude helicopter flights over the San Francisco Bay Area on Monday, February 2, through Wednesday, February 4, ahead of the Super Bowl on February 8. 

NNSA’s Nuclear Emergency Support Team (NEST) Aerial Measuring System aircraft will measure expected background radiation as part of standard preparations to protect public health and safety during the event. 

The public may see a Leonardo AW-139 helicopter, which is equipped with radiation sensing technology. The helicopter will fly at relatively low levels. 

These aerial radiation surveys are a normal and routine part of security and emergency preparedness activities. NNSA is making the public aware of the upcoming flights so citizens who see the low-flying aircraft are not alarmed.

NEST is an element of the Nation’s nuclear or radiological emergency response capability.

The NNSA Aerial Measuring System’s Leonardo AW139 helicopter provides specialized airborne radiation detection systems for measuring contamination.
