Abstract：
Tumor treatment with heavy ion is characterized by the depth-dose curve of heavy ions. So,it is a key to develop physics model for calculating dose. In this paper, the media for calculation have been selected from the chemical component of biological cells,characters of radiobiology and demand of physical dose calculation. A method to calculate does-depth distribution has been developed by using the semi-empirical functions of nuclear fragmentation reaction cross section and total nuclear reaction cross section,and also considering other factors which affect the results of calculation. The results of calculation tally with experimental data and show that the theoretic calculation can be used in the tumor treatment and radiobiology effect research.
