  This paper presents method of gamma-analysis of the soil patterns sampled
soon after of nuclear accident. The method does not require of sample
preparation and intends for analysis of the soil samples with a non-homogeneous
distribution of activity at the depth. Technique of calibration of the detector
efficiency is considered, that have been used when soil blocks sampling by
means of the non-disturbance method (by rings) after Chernobyl accident were
measured.
