New Method of Environmental Assessment Based on the Methods of Self-Organization of Mathematical Models.

The method of generation of mathematical models of the observations defined on an irregular grid of observation data has been proposed. The method is based on self-organization of mathematical models and allows for the reconstruction and forecast (on a regular grid) of the observations fields of a different origin with controlling accuracy. This method could be used to any data field that is presented as a set of values in some region. A space distribution of geophysical (geochemical) parameters in a real geographic region could be considered as the data field of interest. In this study, the method has been used for the generation of the maps of the distribution of the 137Cs and 90Sr radioactive isotopes over the Zhytomir region of Ukraine (consequences of Chernobyl disaster). It is shown that this method allows to improve an accuracy when building the maps of the radioactive isotopes distribution for the cases of the fields defined on a small number of irregularly distributed points.
