Relative Biological Effectiveness for Types of Ionizing Radiation: Parameters and Assessment Techniques
Generalized equations were suggested to estimate relative biological effectiveness (RBE) coefficients for various types of radiation relating to deterministic effects. It was demonstrated that RBE might be calculated using two techniques: as a ratio of equipotent absorbed doses from common γ-radiation and investigated x-radiation and as a ratio of equipotent effects of γ- and x-radiation. Additional (absolute) parameters of biological effectiveness were introduced for types of ionizing radiation. The findings are of radiation medicine and biology interest and may be useful for radiation protection.
