Abstract
Timedependent yields of the most important products of water radiolysis texte rm aq •OH H• H3O+ H2 OH− and H2O2 have been calculated for 60Cophotons electrons protons helium and carbonions incident onto water G values have been evaluated for the interval from 1 ps to 1 μs after initial energy deposition as a function of time as well as after 1 ns and at the end of the chemical stage as a function of linear energy transfer LET covering an interval from approximately 02 up to 750 keV/μm by means of different particle types In this work the modules of the biophysical Monte Carlo track structure code PARTRAC dealing with the simulation of prechemical and chemical stages have been improved to extend interaction data sets for heavier ions Among other newly selected parameter values the thermalisation distance between the point of generation and hydration of subexcitation electrons has been adopted from recent data in the literature As far as data from the literature are available good agreement has been found with the calculated time and LETdependent yields in this work supporting the selection of the revised parameter values
