The regularities of the spatial distribution of ¹³⁷Cs in forest soil at the microlandscape level in semiromophic and hydromorphic conditions in the Bryansk region at different measurement steps with the KORAD radiometer (10, 2 and 0,5 m) are investigated. The variability of the ¹³⁷Cs stock obtained by two devices differing in the size of the sampling area (RPO) is compared: 1) CORAD radiometer 2) sampler D=14 cm. The ratio of the variability of the ¹³⁷Cs distribution obtained by field radiometry to the sampling data (CVcorad/CV sample) for the entire site is 0,63; for the hydromorphic part, B1-1 is 0,87. For the entire site (size 50x80 m), a weak spatial correlation was revealed (the effect of a "chessboard"), for a local hydromorphic site, a strong correlation with a rank of 1,4 m.
