The paper describes developments of the physicochemical part of a comp
uter code system that estimates DNA strand break induction on plasmid
pBR322 DNA. In order to test the reliability of the model, we evaluate
d the dielectric function and the time-dependent yield of chemical spe
cies in the presence of OH radical scavenger or dissolved oxygen. Resu
lts agree with measurements on the radiolysis of liquid water. When a
hybrid model of a liquid inelastic cross-section and a vapour elastic
cross-section is used, energy deposition by vibrational excitations is
estimated to be approximately 11% of total energy deposition.
