Abstract

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Ionizing Radiation and Complex DNA Damage: Quantifying the Radiobiological Damage Using Monte Carlo Simulations

“…For instance, simulations on the effects of gold nanoparticles are mentioned with Geant4-DNA only, but these have been performed with other codes as well, cf. the recent review by Li et al Phys Med 2020 [18].…”

Monte Carlo simulation of free radical production under keV photon irradiation of gold nanoparticle aqueous solution. Part I: Global primary chemical boost

“…Thus, at short time, Monte Carlo (MC) techniques are required to calculate radiation-chemical yields as a function of time. We used the MC code MDM[54,55,56,57], which performs an event-by-event tracking of electrons and ions. Formerly known as the LQD code[54], it was originally developed to track ions and low energy electrons and products of chemical reactions down to very low energies (thermalization) in pure liquid water.…”

Corrigendum to “Intercomparison of dose enhancement ratio and secondary electron spectra for gold nanoparticles irradiated by X-rays calculated using multiple Monte Carlo simulation codes” [Phys. Med. 69 (2020) 147–163]

“…In our paper [1] we presented the dose enhancement ratios (DERs) and the electron spectra for a single gold nanoparticle (GNP) irradiated by a narrow X-ray beam calculated with multiple Monte Carlo simulation codes. During further analysis of the data for an internal EURADOS report, we identified the following inconsistencies in the simulations, which affect the results presented in the above-mentioned article [1]:…”

“…For the aforementioned reasons, Figs. 4-8 and Table 2 presented in our paper [1] were replotted and tabulated in the following.…”
