The purpose of this study is to estimate the yields and the configuration of DNA damages as well as the spatial distribution of the damages along to the tracks of heavy ions using the Monte Carlo simulation. A new Monte Carlo track structure code for any kind of ions from hydrogen to uranium has been developed and applied for simulation of the induction process of DNA damage. In our presentation, the calculated DNA damage spectrum for some selected types of ions for different energies is shown and discussed by comparison with available experimental data.
