Simulation based on diffusion kinetic model has been carried out to investigate on "initial" track structure at 10 s formed by heavy-ion irradiation and to compare with reported values such as primary yields in pure water and (Fe) in the Fricke solution. Several dose distributions proposed in literatures were taken into the simulation. Spatial distributions of "initial" products at 10 s calculated with Monte-Carlo simulation were compared with the dose distributions reported in the literature.
