The analysis of the efficiency of the absorbed dose depth distribution as a function of the kinetic energy spectrum of a submicrosecond electron beam showed that the use of two operating modes of a submicrosecond electron accelerator, which differ in the amplitude of the accelerating voltage pulse (200 and 300 kV), under irradiation of various materials can provide different effects determined by different depth distributions of absorbed energy. For the constructed spectra of the beam electron kinetic energies, we used a model sample that takes into account the structure and penetration of the material, which determines the conditions for the electron beam absorbed energy distribution over the depth. Based on the experimental data, the absorbed dose in the structural parts of the object was estimated using the example of a wheat seed, and conclusions were drawn about the efficiency of using irradiation modes with different kinetic energy spectra of electrons in the beam.
