Abstract
An approach to the acquisition of retrospective information on the radioactive pollution of the territories in order to organize the radioecological monitoring of environment has been proposed. The approach is based on the application of the method of dendrochronoindication, allowing one to obtain the retrospective information on the delivery and accumulation of radioactive and other materials in the wood rings of the trees. Statistical processing of the massives of the multidimensional retrospective data was carried out using the geoinformation approach based on the combination of the principal components method and spatial analysis using the means of geoinformation systems. It has been shown that the approach proposed allows one to reveal the emergency emissions that took place in the past at the enterprises of nuclear industry and make a well-grounded selection of the sites for the radioecological monitoring in zones of nuclear industry impact.
