Resumen
This work presents a Monte Carlo study of energy depositions due to protons, alpha particles and carbon ions of the same linear-energy-transfer (LET) in liquid water. The corresponding track structures were generated using the Geant4-DNA toolkit, and the energy deposition spatial distributions were analyzed using an adapted version of the DBSCAN clustering algorithm. Combining the Geant4 simulations and the clustering algorithm it was possible to compare the quality of the different radiation types. The ratios of clustered and single energy depositions are shown versus particle LET and frequency-mean lineal energies. The estimated effect of these types of radiation on biological tissues is then discussed by comparing the results obtained for different particles with the same LET. 57 1 209 224 Open University in Milton Keynes in the UK French CNRS [PICS 5873] Saint Joseph University in Beirut (Lebanon) [PICS 5873] French Agence Nationale de la Recherche [ANR-09-BLAN-0135-01] European Space Agency [AO6041-22712/09/NL/AT] FAEPEX foundation at UNICAMP, Brazil French CNRS [PICS 5873] Saint Joseph University in Beirut (Lebanon) [PICS 5873] French Agence Nationale de la Recherche [ANR-09-BLAN-0135-01] European Space Agency [AO6041-22712/09/NL/AT]
