| Description | Journal: Physics in Medicine & Biology The purpose of this study was to generate physical data needed for microdosimetry-based models of proton RBE. Our focus was on the frequency and dose average lineal energies, $y_{F}$ and $y_{D}$. We report data for proton energies from 0.1 to 100 MeV, for spherical volumes 2 to $10^{3}$ nm in diameter. These data were calculated using Geant4-DNA Monte Carlo software. The physics implemented in Geant4-DNA has been extensively tested for this type of calculations but data on $y_{F}$ and $y_{D}$ for protons generated with this code have been very limited. An innovative aspect of our study is that we introduced a straightforward procedure for calculation of $y_{F}$ and $y_{D}$ for polyenergetic beams and presented the data in a format that simplifies these calculations. We compared our data with previous studies that used a different Monte Carlo code and with experimental data. |
