Figure Lengend Snippet: FIG. 6. FLUKA simulation of radial distribution of dose per primary irradiating particle in 1 lm thick cell culture layer exposed to 0.2 cGy of 1,000 MeV/u 56Fe ions. Panel A: Radial distribution of dose of 56Fe ions, heavy ions, 1 keV threshold electrons and the total dose. Panel B: Radial distribution of dose of electrons with various d ray thresholds (1, 10, 100 keV and 1 MeV). Panels C and D illustrate radial distribution of dose from heavy ions (primary and secondary) and electrons, respectively, by superimposing the radial dose area over panel D in Fig. 5, where cells traversed by a primary 56Fe ion track were identified.

Article Snippet: Simulations with the FLUKA multi-particle transport code revealed that fragmentation products, other than electrons, in cell cultures exposed to HZE particles comprise ,1% of the absorbed dose.
