At present, the radioecological situation is characterized by the decrease of pollution densities of higher lying water catchment areas and by wash-out of radionuclides to lowlands, bottom lands and deep into the ground. On this account, increase of surface pollution density takes place in lowlands and flood lands. Comparison of the data on ground water from the weels of constant observation in the near zone shows that the content of 137Cs and 90Sr in ground water is lower than that in surface water by 2...15 and 3...90 times, respectively, in observation sites of the near zone it depends on time and place of sampling
