[Mathematical analysis of genetic effects of low doses of ionizing radiation]. / Matematicheskii analiz geneticheskikh éffektov malykh doz ioniziruiushchikh izluchenii.

The comparative study of effects of low doses of radiation on peripheral blood lymphocytes of persons occupationally exposed to radiation and non-exposed ones was carried out. The main attention was paid to radio-adaptive response forming under consistent exposure to low (0.05 Gy) and damaging (2 Gy) doses of gamma-irradiation. Noticeable heterogeneity in capacity for adaptive response forming in occupational group was revealed. The mathematical model adequate to experimental material was constructed using Kohonen neuronets.

[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.
