Frequency distributions and density functions of distances with simulated linear track structures

Track structures of high-LET particles can be simulated by various linear approaches. The distribution of distances seems to be an important parameter in understanding the type of interactions which occur and the biological effects which these excitations and ionizations will create; therefore, the distance distributions of these simulated track structures were calculated. Three presentations show that their exact appearance depends on the scaling parameter: the number of classes. In one approach the theoretical density of the distances was calculated by the techniques of convolution and by forming mixed distributions which confirm the findings of the simulation.
