Yeast cells incubated at 30 icient laborato C on solid media after gamma irradiation show three periods of delay in division which differ in the way they vary with dose, in reversibility, and in distribution within the irradiated population. Three types of inactivation are found: without prior division, after 1 and after 4 to 7 divisions. The distribution of these forms over the population depends on the dose. The late inactivation effect and recovery are not directly related to the ploidy and are found in haploid and diploid strains, at least if resting cells are gamma irradiated. It is supposed that the wave- like development of damage is a feature of the reaction to ionizing radiations shown by many unicellular organisms, as well as by multicellular ones. (auth)
