UAV systems has developed background radiation monitoring system for Russian meteorology and ecological monitoring corporation Rosgidromet. The base of the system is serially produced scintillational wide-range intellectual x-ray and gamma emission detection module and UAV Supercam S-350 by UAV systems, LLC. Both devices were modified during development.

The new UAV is able to perform the following tasks of radiation monitoring:

+ investigate nuclear and radiation accidents areas on emergency, detect radioactive contamination sources and radioactive plume movement;

+ verify nuclear energy facilities to meet standards, leak detection;

+ monitor ground and air radioactive ecological pollution;

+ scientific research;

+ serve as an instrument for primary anticipation of radiation conditions when working with mobile radiation monitoring labs;

+ perform other tasks requiring urgent detection of x-ray and gamma emission sources.

The UAV with Supercam dosimeter allows to monitor territory by following programmed route automatically or by remote control and transmit data via digital radio channel. The data is then used to build a map of background radiation, showing real-time situation at the object investigated. UAV is able to perform investigation within 56 miles (90 km) radius.

Advantages of Supercam drone in solving radiation monitoring tasks include cost effectiveness, short system setup time and ability to perform measurements in situations which are dangerous for human life.

Rosgidromet representative commented on UAV systems, LLC. work: "Thanks to the new system we now can more quickly and effectively solve tasks, which affect directly on public safety. Its importance is difficult to overestimate. I'm glad we were able to develop such an outstanding modern instrument for radiation background monitoring. The project declared successful, implementation started."
