[Estimation of absorbed dose based on the results of cytogenetic studies of lymphocyte cultures from subjects exposed in the accident at the Chernobyl Atomic Power Station].

Cytogenetic analysis of peripheral blood and bone marrow lymphocyte cultures was performed in 158 persons who had suffered in the accident at the Chernobyl Atomic Power Station. According to these data, in spite of severe local injuries in some cases, hemopoietic tissue of a majority of the patients was exposed to relatively homogeneous irradiation. Doses, estimated by the frequency of dicentrics (per 100 cells), in 7 patients varied within the ranges 10.1-13.7 Gy, in 12--6.1-9.5 Gy, in 16--4-5.8 Gy, in 33--2-3.9 Gy, in 19--1-1.9 Gy, in 42--0.1-0.9 Gy. Dicentrics in 29 patients were undetectable.
