[The dynamic course of the mutation process in human peripheral blood lymphocytes under conditions of exposure to low levels of ionizing radiation].

In seven groups of children living in the areas contaminated by nuclides a significant cytogenetic effect has been detected. The degree of its expression (integral and specific markers) was similar and did not correlate with the density of contamination by radionuclides.

[The detection of multiaberrant lymphocytes in the cytogenetic examination of different groups of people in contact with mutagenic factors].

Data are presented on the frequency of multi-aberrant cells in lymphocytes gained during the period from 1967 to 1992 in some groups of the USSR inhabitants, who contacted with different environment mutagenesis. It is shown that the results of the study of 1500 men give a possibility to account some groups of multi-aberrant cells not to be artifacts and to be induced by some of the mutagens studied.
