Electron track structure analysis by PHITS

A general purpose particle transport simulation code, PHITS is expected to apply dose evaluation in macroscopic systems as well as radiation interaction investigation in nanoscale for study of interaction between radiations and materials. To clear the problem, we developed track structure mode codes of the PHITS. We predicted yields of the DNA damage by the mode. We found that the mode could reproduce experimental results of the DNA damage yields by electron irradiation into the cells. The PHITS could evaluate radiation dose of cellar size. The track structure mode made the prediction of DNA damage yields possible.
