When developing radar monitoring systems for soils and territories in radiation-dangerous urban ecosystems [1, 2], it is often necessary to model the spatial electron-ionic distributions of low-temperature air plasmoids that are formed over highly contaminated soils and territories with radionuclides. Such a model should reflect the unique spatial characteristics of the distribution of electron-ionic concentrations, through which it is possible to reliably identify strong radionuclide contamination of soils and territories. Under the strong radioactive contamination of soils and territories we understand those, in which even a short stay is deadly on human. Such contamination, for example, can occur, when nuclear reactors are destroyed. © Springer International Publishing AG, part of Springer Nature 2019.
