A study was made of the possibility of measuring radionuclide activiti
es by the method of coincidence of electrons with energies of a few eV
emitted from the valence shells of radioactive atoms with nuclear rad
iations. The low energy electrons were detected with a detector equipp
ed with microchannel plates with trochoidal focusing of an original de
sign. Photons were detected with NaI(TI) detectors. A 100 mu m thick p
lastic scintillator was used to detect beta- and alpha-particles. The
investigation shows that it is possible to use this method for accurat
e measurements of radionuclide activity.
