A BETA -dosimetry method is suggested based on studies of electron spectra. A scintillation spectrometer was used. It is shown that the magnitude of the dose is equal to N(dE/dx), where N is the number of BETA particles penetrating an infinitesimally small volume near the examined point: (dE/dx) is the magnitude of ionization losses averaged over the spectrum. It is found that the magnitude (dE/dx) is determined by the maximum energy of the isotope BETA spectrum. It actually does not depend on the depth of the medium and diameter of the source. Graphs are plotted for S/sup 35/, W/sup 185/, TI/sup 204/, Y/sup 91/, and Ce/sup 144/ depth doses, and criteria are suggested for selecting isotopes for optimum irradiation conditions. (tr-auth)
