Abstract

Currently, the threat of nuclear weapons use has increased, with their deployment in new regions, and there are risks of accidents at nuclear power plants and terrorist acts involving nuclear charges. Therefore, remote gamma monitoring is relevant. The ability of UAVs to fly at low altitudes and speeds allows to increase the reliability of gamma monitoring compared to space and manned remote sensing means and to protect UAV operators from radiation exposure compared to ground-based methods, while visualization of monitoring results provides two- or three-dimensional models of radiation distribution on the earth's surface. A review of radiation imaging systems is made: with collimated detectors, with coded aperture, with rotational modulation, Compton imaging, with moving detectors (directional systems). Due to the smallest size and weight characteristics and the ability to operate in a remote gamma field, only the last two systems are currently suitable for use on UAVs. It has been established that systems with movable detectors on UAV platforms allow gamma monitoring in full: search for radioactive sources, mapping of natural radiation background and areas contaminated with radionuclides. Currently, Compton imaging systems allow detection of radiation sources at lower altitudes and speeds, which makes them effective for searching for sources in local areas of the urban environment and indoors, but does not allow mapping of large areas of radiation contamination.
