Nuclear fragmentation reactions in extended media studied with Geant4 toolkit

Neutrons from fragmentation of light nuclei in tissue-like media: a study with the GEANT4 toolkit.

We study energy deposition by light nuclei in tissue-like media taking into account nuclear fragmentation reactions, in particular, production of secondary neutrons. The calculations are carried out within a Monte Carlo model for heavy-ion therapy (MCHIT) based on the GEANT4 toolkit. Experimental data on depth-dose distributions for 135-400 A MeV (12)C and (18)O beams are described very well wi...

beams: a study with the GEANT4 toolkit

We study the spatial distributions of β-activity produced by therapeutic beams of He and C ions in various tissue-like materials. The calculations were performed within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit. The contributions from positronemitting nuclei with T1/2 > 10 s, namely 10,11C, N, 14,15O, 17,18F and P, were calculated and compared with experiment...

Distributions of deposited energy and ionization clusters around ion tracks studied with Geant4 toolkit.

The Geant4-based Monte Carlo model for Heavy-Ion Therapy (MCHIT) was extended to study the patterns of energy deposition at sub-micrometer distance from individual ion tracks. Dose distributions for low-energy (1)H, (4)He, (12)C and (16)O ions measured in several experiments are well described by the model in a broad range of radial distances, from 0.5 to 3000 nm. Despite the fact that such dis...
