Representative survival curves for cells of different radiosensitivity (A) or different oxic conditions (B) exposed to x-rays or charged particles
The relative biological effectiveness (RBE) and oxygen enhancement ratio (OER) are calculated according to their definition for the same survival level. In (A) solid lines represent radioresistant (R) cells and broken lines represent radiosensitive (S) cells. In (B) solid lines represent hypoxic (H) cells and broken lines represent normoxic (N) cells.
