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].

• EURADOS organized an inter-code intercomparison of dose enhancement of gold nanoparticles irradiated by kVp X-ray spectra. • Variations and uncertainties of dose enhancement are observed by using multiple Monte Carlo codes. • This study gives a reference range of dose enhancement in simulating gold nanoparticles irradiated by x-ray spectra. • This intercomparison improved the simulation performances by identifying differences in settings, scoring and analysis. • Further inter-code intercomparisons ensure a high quality of dose assessment for gold nanoparticle-assisted radiotherapy.
