Enhancement by fractionation of biological peak-to-plateau relative biological effectiveness ratios for heavy ions. [Recovery of rat jejunal crypt cells after partial- or whole-body irradiation]

Journal Article · · Int. J. Radiat. Oncol., Biol. Phys.; (United States)
Recovery from sublethal damage of jejunal crypt cells was measured after fractionated irradiation with /sup 137/Cs, or accelerated helium ions, carbon ions, and neon ions. Cells irradiated with the accelerated particles showed less recovery than cells irradiated with /sup 137/Cs. For each accelerated heavy ion, cells irradiated in the peak region of the beam showed less recovery than cells irradiated in the plateau region. This resulted in an enhanced peak-to-plateau relative biological effectiveness (RBE) ratio which augments the already favorable physical depth-dose distribution for these beams.
