[Method of quantified complete estimation of soil properties for prediction of radionuclide accumulation by plants]

A method is founded on consideration of soil as three-phase system where soil solution reaction (pH), absorbing capacity (E) and content of organic matter (OM) are the main characteristics. The method of complete estimation of soil properties (CESP) for quantified analysis of radionuclide soil-to-plant TF dependence on soil properties is grounded and proposed. The area of an effective section (relative units)2 calculated as an area of the triangle with apexes lying in co-ordinates of normalised vectors pH, E and OM in three-dimensional space for complete estimation is used. It is shown that the dependence of 137Cs TF to various crops on CESP can be approximated by equation of power law.
