Continuous spectra of beta particles and gamma rays emitted in the decay of short-lived fission products have been measured. These spectra, which cover the complete energy range available, can be used for checking results of detailed spectroscopic work on the decay of the nuclides studied. Another application of basic nature is the use of the beta spectra to evaluate the antineutrino spectrum in the vicinity of a nuclear reactor. There are also many applications of these spectra in nuclear technology, for instance the evaluation of the shape of the gamma-ray spectrum in a nuclear reactor and in nuclear waste. Accurate average beta and gamma energies, obtained from the spectra, are essential input data for summation calculations of the heat developed in nuclear fuel elements by the decaying fission products.
