LANDSCAPE-GEOCHEMICAL AND RADIOECOLOGICAL MAPPINGS OF THE AREAS CONTAMINATED WITH RADIONUCLIDES

A technique has been developed to construct radioecological maps of th e territories polluted after Chernobyl accident. It assumes constructi on of a series of maps in one and the same scale to perform structure division of factors of radionuclides migration in the environment. Com bination of these maps and a global radioecological data included into a geoinformation system allows one to perform a valid spatial extrapo lation of radioecological models as well as to recommend correct land tenure, making decisions, and risk estimating. A series of maps of a B ryansk region with 1:200 000 scale was choosen to demonstrate the desc ribed technique.
