[Rapid recovery in diploid yeast cells irradiated sequentially with fast electrons and alpha particles].
In the present work, fast repair after combined irradiation by fast electrons and alpha particles was studied in diploid yeast cells Saccharomyces cerevisiae of wild-type XS 800 and its radiosensitive mutant XS 1898. It was shown, that the fast repair significantly contribute to detected survival of the wild-type cells, while this repair is absent in XS 1898 mutant cells. An efficiency of the fast repair under combined irradiation (electrons + alpha particles), assessed on DMF of alpha particles, is lower, than that under irradiation by electrons and alpha particles separately.
