The nature of the radionuclide contamination resulting from Chernobyl disaster is in its spatial and aggregate heterogeneity determined by the interaction of systematic and incidental factors. To study the radionuclide migration in the soil-plant system, an independent statistical index of contamination heterogeneity H = RAsAp is proposed which is calculated as a Brave-Pirsens coefficient of linear correlation between radioactivity of soil and dry biomass of plants grown on it and which allows to determine relative range of contamination that appears in the form of "hot particles". An adequacy of this index is substantiated, and it is used to analyze the experimental results on radionuclide migration.
切尔诺贝利灾难造成的放射性核素污染的性质，在空间和总体上具有异质性，这是由系统因素和偶然因素的相互作用所决定的。为了研究放射性核素在土壤 - 植物系统中的迁移，提出了一个污染异质性的独立统计指标H = RAsAp，它是作为土壤放射性与生长其上的植物干生物量之间的线性相关的布雷斯 - 皮尔森系数来计算的，并且可以确定以“热点粒子”形式出现的污染的相对范围。该指标的充分性得到了证实，并用于分析放射性核素迁移的实验结果。
