| Outline of Final Research Achievements |
In this study, we have integrated DNA damage simulations using a Monte Carlo simulation code and Bystander effects simulation models into a macroscopic dose calculation algorithm to seamlessly implement cell lethality estimation integrating DNA damage caused by direct radiation and intercellular networks. We have worked on the implementation of this method.
We compared the DNA damage obtained by DNA-level Monte Carlo simulations with experimental cellular data and presented the validity of the simulation results.
