Photoreactivation of damage induced by ionizing radiation in yeast cells.
Experimental data on photoreactivation of damage induced by ionizing radiation in yeast cells are presented. The value of photoreactivation was found to be the highest for the following conditions predicted by us as optimum ones: large volume of irradiated suspension, hypoxia and high energy sparsely ionizing radiation. A comparison of data for yeast and bacterial cells shows that Cerenkov emission from ionizing radiation may produce photoreactivated pyrimidine dimers in both prokaryotic and eukaryotic cell systems.
