文摘Using the relation of radial dose distribution which is inverse proportion to square of radial distance, and considering angular distribution of secondary electrons, an analytical formula of mean dose deposited in extended volume around an ion is given and the inactivation cross sections of heavy ions are calculated. The results are in reasonable agreement with experimental data. Compared to the numerical integral methods, the method using analytical formulae is straightforward and simple.
