Heavy ion beams, are characteristic of energy deposition effect and Bragg peak. Compared with low-LET ionizing radiation, including γ rays, X-rays and electrons, they have higher linear energy transfer (LET) and higher relative biological effectiveness (RBE). These characters made them become a novel and efficient mutagens. It has been reported that heavy ion beams could induce growth suppression, and lethality in plants after radiation.
