Abstract
The evidence for a decreased enhancement ratio of oxygen and an electron affinic radiosensitizer (misonidazole) at low doses is presented, and the mechanism of this effect is discussed. The factors which influence the magnitude of this effect, as well as the dose levels at which the effect will be significant, are identified. This will allow further characterization of this phenomenon in the future. An approach by which present and new hypoxic radiosensitizers could be made more effective at low doses is indicated.
