In this study, we investigated lethal effects and relationship between LET and RBE for different LET radiation using the freeze-dried cells of the radioresistant bacterium . The radioresistance of the cells to helium, carbon and neon ion beams were almost equal to that of -irradiated cells. Unlike other organisms, did not show the dependence of LET on RBE at a range of LET from about 0.2 to 441 keV/m. These results suggest that could repair the clustered damage effectively.
