A Chernobyl 137Cs contamination study as an example for the spatial structure of geochemical fields and modeling of the geochemical field structure
چکیده انگلیسی
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. 137Cs 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.
