[A comparative study of the frequency of stable and unstable chromosome aberrations in the gamma irradiation of human lymphocytes in vitro].

Comparative studies of the yield of stable and unstable chromosome aberrations have been carried out in human lymphocytes gamma irradiated in vitro within the doze range 0.1--1.0 Gy. It was observed that the yield of unstable chromosome aberrations (dicentrics and centric rings) is satisfactorily described for discovered dose range with linear-quadratic approximation. For stable chromosome aberrations in G-banded chromosome the dose response dependence was less expressed. The studies revealed non-random involvement of different chromosomes in translocations, and the most frequently involved are 1 and 13 chromosomes.
