Dose-response relationship of the yield of chromosome aberrations in a human lymphocyte culture following gamma-irradiation at high doses

A study was made of the yield of chromosome aberrations in a human lymphocyte culture at the G0 stage after 60Co-gamma-irradiation with doses of 5-12 Gy. It was shown that a linear-quadratic dependence of the aberration frequency observed with median doses became purely linear at high doses.
