CARTOGRAPHIC APPROACHES FOR STUDY THE MIGRATION OF ARTIFICIAL RADIONUCLIDES

Abstract

Stages of creation of an information-cartographical database according to distribution of artificial radionuclides in landscapes are considered in the article. Necessity of use of geoinformation technologies is shown at ekologo-radiochemical researches. The technique of maps creation, which is based on the theory about river basins and representations about geochemical arenas, is described. The structure of geoinformation layers of an ekologo-radiochemical database is considered in detail. There are described sources for drawing up of cartographical layers, their maintenance and technology of creation. On the basis of the stated technique ekologo-radiochemical division into districts of Murmansk and Arkhangelsk areas is spent and the ekologo-radiochemical information-cartographical database of regional level is created.
