Double strand breaks in the DNA of Bacillus subtilis cells irradiated by heavy ions.

U Micke1, G Horneck, S Kozubek.   

Abstract

Cells of Bacillus subtilis strain TKJ 8431 in stationary phase were irradiated with X-rays (150 kV at DLR) or heavy ions (Ne, Ar, Pb with residual energies between 3 and 15 MeV/u at GSI). The action cross section for the formation of double strand breaks in the DNA of the irradiated cells follows a similar dependence on mass and energy of the ions as has been found for various biological endpoints, e.g. inactivation, mutagenesis and repair efficacy.
