Table 2. RBE values obtained for the two proton radiation qualities.
mid-SOBP | plateau | |
---|---|---|
RBE30Gy± se | 1.60 ± 0.32 | 1.41 ± 0.08 |
RBE20Gy± se | 1.20 ± 0.04 | 1.13 ± 0.08 |
Dose dependent RBE values (± standard error) calculated on basis of the obtained survival rates 4 dpi with protons of the mid-SOBP and the entrance plateau relative to 6 MV photons.
