Intercomparison of micro- and nanodosimetry Monte Carlo simulations: An approach to assess the influence of different cross-sections for low-energy electrons on the dispersion of results

An intercomparison of microdosimetric and nanodosimetric quantities simulated Monte Carlo codes is in progress with the goal assessing uncertainty contribution to results due uncertainties electron interaction cross-sections used codes. In first stage intercomparison, significant discrepancies were found for as well simulations a radiation source placed at surface spherical water scoring volume. This paper reports insight gained from further analysis, including additional microdosimetry case where observed distributions could be traced back difference between track-structure condensed-history approaches. Furthermore, detailed investigations into sensitivity alterations inelastic scattering are presented which conducted lead up definition an approach second come. The suitability simulation sought contributions discussed proposed framework described.
