Comparison of Geant4-DNA simulation of S-values with other Monte Carlo codes Universiteit Hasselt

Thierry André, Filippo MORINI, M. Karamitros, R. Delorme, C. Le Loirec, L. Campos, C. Champion, J.-E. Groetz, M. Fromm, M.-C. Bordage, et al.
Monte Carlo simulations of S-values have been carried out with the Geant4-DNA extension of the Geant4 toolkit. The S-values have been simulated for monoenergetic electrons with energies ranging from 0.1 keV up to 20 keV, in liquid water spheres (for four radii, chosen between 10 nm and 1 μm), and for electrons emitted by five isotopes of iodine (131, 132, 133, 134 and 135), in liquid water spheres of varying radius (from 15 μm up to 250 μm). The ...

Investigation of the anisotropic distribution of microdosimetric quantities in the vicinity of X-ray-irradiated gold nanoparticles Universiteit Hasselt

Jonathan DERRIEN, Nicolas Pauly, Jean-Francois Adam, Brigitte RENIERS
High-Z nanoparticles incorporated in tumors have great potential to enhance radiotherapy treatments by increasing the absorbed radiation dose in the vicinity of the nanoparticle. However, current Monte Carlo simulations estimate dose enhancement metrics in 1D, neglecting the anisotropy of the energy deposition around the nanoparticle. This could have radiobiological consequences and affect treatment accuracy. Accurate knowledge of the spatial ...
