metadata.value: The article presents results of an express radon survey on the territory of the Pechora-Kozhvinsky
  and Kolvinsky megswells, which are part of the Pechora-Kolvinsky aulacogen. Radon
  studies were carried out along profiles across the large structure-forming faults, identified on
  the basis of seismic data. The results show that faults in the radon field correspond to areas with
  increased values of the radon volumetric activity. In the course of radon studies, main patterns
  of the manifestation of faults in the radon field were established. The faults may correspond to
  the maxima of volume activity of radon against the background of low values or to zones with a
  minimum concentration of radon. In addition, areas with abnormal radon concentrations not
  associated with known fractures were identified. The systems faults are characterized by wider
  radon anomalies or alternation of maxima and minima of radon volumetric activity along the
  profile. The maximum radon concentration is recorded in the fault zones that are closest to the
  surface, as well as in faults along which large amplitudes of vertical displacements are noted.
  Similar levels of radon concentration are observed within the normal faults and thrust faults,
  covered by sedimentary rocks. Most of the studied faults, according to the relative indicator of
  radon activity, belong to the group of high radon activity. The concentration of radon in the soil
  air within the faults varies both in the transverse and longitudinal directions. In some areas,
  the radon volumetric activity of at the same level at different times. This proves the existence
  of a constant radon flux. The main factors affecting the formation, transport to the surface, and
  accumulation of radon in the soil are the composition and depth of the basement, the internal
  structure of fault zones, the degree of porosity and fracturing of rocks and modern geodynamics
  of the region. Thus, radon survey as an additional method to other geophysical methods can be
  used to map faults and identify various blocks that differ in fluid-geochemical features.
