Unoccupied aerial vehicles, better known as drones, have rapidly advanced from a quirky, high-flying novelty to a versatile workhorse.
They are tools for search and rescue, traffic monitoring, weather monitoring, and perhaps even package hauling.
One day, they may work with humans to augment the task of conducting surveys to detect low levels of radiation—information that could contribute to the decommissioning of sites no longer needed for nuclear-related energy production or research.
