The instrument can be used in operation by NPP personnel and radiation monitoring services, Emergency control ministry, health, environment protection authorities, agricultural producers, builders, customs and other organizations, which are working, as a rule, under the normal conditions, but engaged in detection of local radiation sources or single objects, contaminated with radioactive nuclides.
