Radiation emissions within territories that accommodate nuclear power facilities are monitored by stationary gamma radiation measuring systems. Any facilities that may contemplate the hazard of radioactive emissions must meet the safety requirements both in terms of normal conditions of their operation and in case of accidents. Thus, radioactive materials now in use must comply with strict rules.
The account for and control of radioactive materials, their proper application, compliance with the rules and security measures minimize their impact on the environment. However, the loss of professional control over the above materials (various emergencies, losses in the course of transportation, plunders) may involve serious consequences.
One of the most effective ways of reconnaissance of territories exposed to radioactive contamination to assure the search for the sources of radionuclides represents remote measurement of surface gamma radiation performed by radiation meters installed on unmanned airborne vehicles (UMAV). The main advantage of UMAV is that it may be used as the carrier of radiation meters. In addition to the gamma radiation meter, the system can take a video of different sources of hazards.
The article demonstrates the results of tests of the unmanned radiation meter designated for remote sensing of the surface gamma radiation. The option of assessment of the intensity of the radiation and the concentrations of radionuclide fields is considered. It is noteworthy that the technology of remote scanning of the area can also be used for environmental surveying, technical inspection of structures and buildings, fire detection, photography of high-voltage lines and other facilities located in remote areas.
