¹²C⁶⁺-ions of different parameters irradiation level and its effect on the growth rate of D. natronolimnaea smgcc1.2736 strains cells in %. (A-D) ¹²C⁶⁺-ions were accelerated up to 30 MeV/u, and their LETs were 60, 80, 100 and 120 keV/μm, with a dose rate of 0.5-1.5Gy. (E-H) ¹²C⁶⁺-ions were accelerated up to 45 MeV/u, and their LETs were 60, 80, 100 and 120 keV/μm, with a dose rate of 0.5-1.5Gy. (I-L) ¹²C⁶⁺-ions were accelerated up to 60 MeV/u, and their LETs were 60, 80, 100 and 120 keV/μm, with a dose rate of 0.5-1.5 Gy. (M-P) ¹²C⁶⁺-ions were accelerated up to 90 MeV/u, and their LETs were 60, 80, 100 and 120 keV/μm, with a dose rate of 0.5-1.5 Gy.
