Abstract: A cellular survival model and the cross section calculation with low and high LET for ion irradiation were presented. Based on our formula of surviving fraction calculation, the survival data of Chinese hamster cell (V-79 ) for ion irradiation including He, Li, B, C, O, Ne and Ar were calculated; the cross sections for ion irradiation including He, Ni, C, Ar, Kr, Xe and U were shown. The calculated results show that the presented model is a good description of radiation effects of V-79 cell for different ion irradiation. In this model splitting energy between ion-kill mode and gamma-kill model is avoided, the calculated results of cross section needn’t be multiplied by a factor to fit the experimental data.
