Calculated LET for proton of 200 MeV and carbon of 1 GeV propagating in water as a function of penetration from SRIM code (Wishart and Rao 2010; Ziegler et al. 2010). Plots exhibit peaks of LET, namely Bragg peak, corresponding to the last slowdown of the particle in liquid water. These plots do not account for nuclear processes like fragmentation
