Energy deposition in small cylindrical targets by ultrasoft X-rays

Abstract
A Monte Carlo technique has been employed to calculate the energy deposition events in small cylindrical targets (<or=100 nm), including sizes which represent the DNA duplex, nucleosome and chromatin fibre, by simulated electron tracks from C (278 eV), Al (1487 eV) and Ti (4509 eV) characteristic ultrasoft X-rays in water. Detailed examples of input data tables for the generation of electron tracks produced from the X-ray photon interactions are presented. Frequencies of energy deposition events per gray for target sizes from 1 to 100 nm are given and comparisons have been made with radiations of different qualities.
