title: Multifractal structure of the ¹³⁷Cs fallout at small spatial scales.
abstract: Regardless of the surface area of the site, the spatial distribution of radioactive contamination of soils with ¹³⁷Cs for Chernobyl fallout is described by a lognormal distribution. Moreover, the spatial pattern of the radioactive contamination of soil is random geometrical multifractal field. Due to that, any contamination spot, when studied in detail, decomposes into a multitude of small spots decomposing further into a multitude of smaller spots etc. Similar patterns are apparently characteristic for fallout of other radionuclides, the Fukushima fallout, as well as atmospheric fallout of non-radioactive dust and aerosols.
