In this work cross sections for the DNA and for attached proteins are calculated and included in the Monte-Carlo modelling of radiation induced DNA strand breaks in cellular environment for the first time. Electron cross sections for the DNA are derived by the Deutsch-Märk formalism and by the binary-encounter-dipole theory, using ab-initio molecular orbital calculations, cross sections for the photons are affiliated from atomic composition. The consideration of these cross sections in the simulation predicts an increased number of single and double strand breaks for ultra soft X rays with energies between the carbon and oxygen K absorption edge, particularly, if DNA is folded and proteins are attached.
