Great read from the BBC about Chernobyl mapping techniques, future plans for the area, and hopes for protocol refinement:
Fixed-wing craft are first used to make a general radiation map by flying at about 40mph (65km/h) just above the treetops, in a grid pattern.
Places of interest are then followed up with rotary-wing drones.
These can hover and use their sensors to acquire high-resolution, 3D information.
The survey conducted in April essentially confirmed the current understanding of the radiation distribution in the forest, but in far greater detail than has previously been available.
The drones also identified a few unexpected hotspots.

Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
