ANNOTATION 

The article presents the results of studies of the near-surface layer of the soil cover (up to 10 cm) of the territory of the Sughd region near the influence of anthropogenic objects. Soil cover samples were analyzed by gamma spectrometric method for the activity concentrations of isotopes (²³⁸U, ²²⁶Ra, ⁴⁰K and ¹³⁷Cs). Peculiarities of variation of radioactive isotopes in soil samples have been established. The obtained results are compared with the data of south-central Tajikistan. A conclusion is made about the influence of certain objects on the radioecological state of the soil cover of Northern Tajikistan.

KEY WORDS

radioactive isotope, specific activity, radioactive tailings, isotopic analysis, soil samples, natural radioactive isotopes, radioactive contamination ²³⁸U, ²²⁶Ra, ⁴⁰K, ¹³⁷Cs.
