Development of database management for the analysis of large scale radioecological accidents

Summary form only given. Some different database management program complexes were developed for creation and work with the Central Data Bank, connected with the long term consequences of the Chernobyl accident. In this data bank, the information has been accumulated for about 10000 populated areas belonging to 15 oblasts (regions) of Russia. The total number of data types (fields) is about 600.
