Abstract: | An estimation of dose around the trajectory of an ion has been made by use of Tabata and Ito's energy deposition algorithm for electrons which takes into account transmission coefficient. The result of the calculation, as well as Butts and Katz's dose, is successfully applied to the interpretation of inactivation cross sections of vegetative cells of E. coli Bs−1, and E. coli B/r and of B. subtilis spores for He, C and N ions. |
