Abstract: Remote radiation sensing technologies are essential for radiation safety and environmental security measures. The use of unmanned aerial systems equipped with gamma-ray and neutron sensors enables monitoring of ionizing radiation in hard to reach hazardous zones where the contamination is unknown. To keep personnel away from the radiation exposure by using remote measurement techniques, these sensors should be integrated into robotic platforms, and the analysis of sensorís signals should be automated and carried out onboard. Two sensors were integrated into an octocopter aerial platform to address this need: a semiconductor Cadmium Zinc Telluride gamma-ray sensor and an elpasolite Cs2LiYCl6:Ce3+ scintillator based gamma/neutron sensor. To allow easy deployment in the field, both radiation sensors were designed as plug-and-play components using the Robot Operating System for onboard processing of the sensorís data and for fusion of the processed data with the real time kinematic GPS information.
