The main factor differentiating low-linear energy transfer (LET) and high-LET therapies is the amount of ionization along the path of the beam. (A) Low-LET radiation is sparely ionizing, and multiple exposures may be used to adequately irradiation target tissues. (B) High-LET radiation causes dense ionization along the course of the beam.
