NNSA to Conduct Aerial Radiation Assessment Survey over South Florida ahead of G20 Summit, Nov. 3-5
WASHINGTON - The National Nuclear Security Administration (NNSA) will conduct low-altitude helicopter flights over Miami and surrounding areas Tuesday, Nov. 3, through Thursday, Nov. 5.
NNSA's Nuclear Emergency Support Team (NEST) Aerial Measuring System aircraft will measure expected background radiation in support of the 2026 G20 Leaders' Summit.
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 surveys are a normal 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 America's nuclear or radiological emergency response capability.
