A Chernobyl ~(137)Cs contamination study as an example for the spatial structure of geochemical fields and modeling of the geochemical field structure

摘要

A proposal is presented to treat the spatial distribution of chemical elements as a continuous numerical field with a specified structure where each value depends upon the others reflecting the deterministic character of the field. ~(137)Cs contamination stemming from the Chernobyl accident has been studied to demonstrate the regular spatial structure of the geochemical field. It is shown to consist of a system of polycentric anomalies of initial and secondary origin that can be followed on different spatial levels. A regular spatial structure is shown to be reflected in the shape of a frequency histogram. Mathematical modeling of mono- and poly-centric geochemical anomalies, with the help of a digital conical projection and production of frequency histograms, are used to demonstrate the non-random character of geochemical data and the potential for further development of a non-stochastical approach in the study and prediction of spatial structures for geochemical fields that can be based on the theory of mathematical field and its numerical modeling.
