Contour statistics, topological self-similarity and conception of representative selection for the analysis of site contamination

The article raises the issue of determination of minimized selection that maintains the morphology of global radionuclide field. The article attempts to find approach to the task. At present the nature of problems, basic statistics and outliers in one-dimensional representation and their generalization in three-dimensional representation. The article introduces a concept of topological self-similarity, gives examples pertaining to the test site 'Irtysh'. (author)
