Abstract
Purpose: To explain the dose survival data for low energy ion irradiation in bioorganisms. Material and methods: Applying DNA target theory and considering physical processes of low energy ion radiation, a mathematical dose-survival model was derived to analyze the data of low energy ion irradiation of bioorganisms. Results: The survival fraction S of bioorganisms after a dose D of low energy ion irradiation was: [image omitted] The analysis showed that survival fraction of bioorganisms under low energy ion irradiation can be well fitted with this formula. Conclusions: It was shown that the dose-survival effects of low energy ion irradiation in bioorganisms were related to the physical processes of low energy ion irradiation and repair effects that can be explained by momentum transfer processes occurring with low energy ion irradiation.
