[Dependence of the radiosensitivity of yeast cells on the LET of radiations. Experiments on haploid cells].
The previously developed model was used to study the dependence of radiosensitivity (D0(-1) of Saccharomyces cerevisiae (the wild type and radiosensitive mutant) on linear energy transfer (LET) of ionizing radiation. D0(-1) (L) of haploid yeasts was shown to be associated, to a certain extent, with the capacity of radiation damages repair. As to the wild-type cells, the above function was represented by a curve showing a maximum, while a descending curve was characteristic of the radiosensitive mutant cells deficient in radiation damages repair. The influence of the repair processes on cell radiosensitivity decreased with increasing LET.
