Modeling the spatial distribution of the volumic radiant energy and absorbed dose of radiation in the DNA structure under accelerated heavy ions

Model approaches are developed to the description of the mechanism of the formation of different types of atomic-level DNA lesions under accelerated heavy ions. The radial distribution of volumic radiant energy and the absorbed dose are calculated in accelerated 4He, 12C, and 40Ar ion tracks in the energy range of 3-20 MeV/nucleon. The spatial location of the atoms of an adenine-thymine nucleotide pair is compared with the calculated radial dose and volumic radiant energy distribution
