[The topological method of analysis of ground contamination of former nuclear test sites]. / Topologicheskii metod analiza ploshchadnykh zagriaznenii territorii byvshikh iadernykh poligonov.

The method of topological description of former nuclear tests in demonstrated in this paper. The information about the field is extracted from the topology of 2D crossections of 3D surfaces constructed on experimental data. The complexity of izolines' system for each cross section in estimated by algebraic sum of contours bounded the areas where the field is higher then the given level. That gives a possibility to do morphological analysis of radionuclide fields using archive data and can be used for ecological diagnosis of different contaminations. The using of this method is shown on some examples.
