Furthermore, this edition presents a comprehensive treatment of the Coulomb scattering on screened nuclear potentials resulting from electrons, protons, light- and heavy-ions ranging from (very) low up to ultra-relativistic kinetic energies and allowing one to derive the corresponding NIEL (non-ionizing energy-loss) doses deposited in any material.
