Projectile charge effect on radial dose due to the irradiation of a heavy particle

Moribayashi, Kengo

Radial dose has been employed in the treatment planning system for heavy particle cancer therapy in order to estimate the cell survival after the exposure to a heavy particle. However, there are no studies involving the detailed examination of the physical phenomena that occur near the trajectory of a heavy particle before ours. Here, we study the projectile charge () effect on radial dose. For = 3 MeV/u, we may be able to treat only = 6 for the simulation of radial dose because the mean projectile charge state () is about 5.8, where is the energy of a heavy particle. However, becomes about 5.0 at = 1 MeV/u, then, we must consider effect. We will show the radial dose of heavy particles with = 1 and 2 MeV/u using in this presentation.
