OER as a function of LET up to 3,850 MeV/cm. OER = 1.00 at 19,400 MeV/cm (5.2 MeV/amu Ar ions). In the context of risk cross-section it is found that the increased cell killing cross section is increased by O 2, in a diminishing fashion, up to about 2200 MeV/cm (Figure 4). Also the cross ................
