Description

Stationary phase cells of the diploid yeast strain 211 were X-irradiated in stirred aqueous or D2O suspensions, in air or in nitrogen. The addition of sodium azide (0.05 M) which quenches singlet oxygen had no effect on survival after exposure of aqueous suspensions in air or in nitrogen. Oxic sensitivity was not changed for cells irradiated in D2O, although D2O enhances the life-time of singlet oxygen. There was significantly less survival after irradiation in D2O and nitrogen. The results indicate that singlet oxygen does not contribute to the radiobiological oxygen effect. (U.K.)
