THE OXYGEN ENHANCEMENT RATIO DEPENDENCE ON THE ABSORBED DOSE AND RADIOBIOLOGICAL CHARACTERISTICS OF IRRADIATED CELLS
The paper presents the analytical method for calculating the oxygen enhancement ratio (OER) in the study of oxygen effect mechanisms. The analytical expressions for OER based on multitarget and lin- ear-quadratic models of cell survival were obtained. The relationship between OER and radiation dose was assessed for cells with specific radiobiological parameters. A satisfactory agreement between cal- culated results and experimental data was obtained.
