A methodical approach used at the Analytical Center of the United Institute of Geology, Geophysics and Mineralogy SB RAS for a retrospective estimation of radioactive fallouts is described in the paper.  The method is based on sampling of soils of representative (informative) landscapes. Such landscapes are auto-morphous elementary landscapes of hilltops, water dividing surfaces, flattened slopes where the primary radio-nuclide fallouts are maximally preserved. A comparison of efficiency of this approach and its checking on a regular network is made. Advantages of checking informative landscapes for retrospective estimation of radioactive fallouts over sampling in a regular network are demonstrated.
