Water radiolysis with heavy ions, from helium to iron ions, of very high energies up to 28 GeV (namely several hundred MeV per nucleon) has been studied in this work. Simulations based on diffusion kinetic model were performed to examine correlation between initial track structures at the beginning of the chemical stage, 10-12 s, and primary yields as well as to estimate the validity of classical track structure model for highly energetic heavy ions.
