Zusammenfassung:First biological models of radiation action were based on the average energy deposited in the cell nucleus. Later theories have stressed the importance of the energy deposition at the nanometer level. Clusters of ionizations generated by K-electron removal seem to be a highly efficient mechanism for the induction of cell inactivation by heavy ions. Calculations and experimental results reported here support this hypothesis.
