Abstract: Using C# development language, VisualStudio 2010 and ArcGIS Engineering 10.2 as the development environment, Oracle 11G as the data repository, ArcSDE 10.2 for spatial data exchange, we constructed a data management information system for geological environment radiation monitoring in Guangdong Province, through system integration, with terrestrial Gamma radiation dose rate, in-place gamma energy spectrum, as well as water body, mud, soil, rock and other sample sub-banks included. It has the advantages of complete function, strong universality, stable system, high operating efficiency, intelligent drawing, friendly and beautiful interface, etc., which provides a reliable technical support for radiation environment supervision and management in the region.

Key words: Geological environment radiation , Terrestrial gamma radiation, Database, GIS
