There are scarce data on the content of lanthanides in the soils of Russia, which is explained by the difficulties in their identification. The improvement of X-ray radiometric analysis permitted us to analyze a significant group of lanthanides in soils, i.e., La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, and Dy. Methods of diagnostics are developed for different groups of lanthanides. The new procedure permitted achieving high accuracy in the measurement; the limit of the lanthanide identification in soils is equal to 2–5 mg/kg. The new procedure allows revealing the particularities of heavy lanthanides’ distribution depending on the lithogenic and anthropogenic factors. The procedure is applicable for revealing the technogenic anomalies of heavy lanthanides and determining their content in soils within positive and weakly negative anomalies.
