Cuts (so-called production thresholds) are applied to the EM processes which have infrared divergence. In Geant4, cuts are defined in length. Thus, EM processes with infrared divergence (e.g. ionization process) generates secondaries only with ranges above the cuts. There is no way to know the number of secondaries which are not generated because of their shorter ranges, while kinetic energies of such tiny particles are accumulated as the energy loss along the step. Please note that cuts are applied only to the processes with infrared divergence. Thus, other processes can generate secondaries of full energy spectrum. If you do not want to track secondaries but just count them, follow the suggestion Vladimir wrote.
