The statistical properties of spatial patterns of radionuclide deposition are reviewed, making use of data for Chernobyl deposition of radionuclides 90Sr, 137Cs, 238Pu, 239+240Pu, and 241Am on sites and soil not cultivated after the accident. Examples considered in the article demonstrate how radionuclide deposition is described by the family of lognormal distributions that, along with multifractal spatial patterns of deposition, is an essential feature of their nature. Key results and conclusions of the article are applicable to the deposition of non-radioactive contaminating substances.
