Gamma spectrum and gamma activity measured from unmanned aerial vehicles (UAV)

The technology for remote mapping of terrains with suspected gamma radioactive contamination using unmanned aerial vehicles (UAV) has been explored.The principles of selection of gamma detectors suitable for embedding in UAV have been discussed. Described are the approaches to creating a flight plan for a line and point model for data collection from the terrain and the techniques of gamma radioactive contamination mapping. Test data from artificially generated radioactive contamination are presented and data collection techniques are described. Finally, a particular example has been given for data processing and mapping of the supposed radioactive contamination.
