As Las Vegas prepares for New Year's Eve, the National Nuclear Security Administration will conduct low-altitude helicopter flights over the Strip from December 29 to 31 as part of security preparations. These flights, using the Leonardo AW-139 helicopter equipped with advanced radiation-sensing technology, will measure background radiation levels, according to News3LV.

Residents and visitors may see the helicopters in the sky, but no disruptions or road closures are expected, as reported by 8NewsNow.  The operations are conducted by National Nuclear Security Administration’s Nuclear Emergency Support Team to ensure public safety during the celebrations.

The National Nuclear Security Administration conducts low-flying helicopter flights, including the Leonardo AW-139, before large public events like the Las Vegas celebration and the Super Bowl. These flights are part of safety measures, and the National Nuclear Security Administration says there is no need for concern.
