A comparison of the number of chromatid aberrations with dose, estimated from the frequency of dicentrics, in the cytogenetic study of lymphocytes in subjects involved in the accident at the Chernobyl Nuclear Power Station

A study was made of the frequency of chromatid aberrations in lymphocyte culture of subjects affected by the Chernobyl accident as a function of dose estimated by the incidence of dicentrics. The average number of chromatid aberrations was nearly the same within the dose range from 0 to 5 Gy exhibiting a tendency towards growth with dose. A high individual variability of the chromatid aberration frequency was observed.
